Description

LFMP and NMC cathode active materials mixtures for Li-ion secondary batteries and preparation method therefor TECHNICAL FIELD

[0001] The present disclosure concerns cathode active materials for rechargeable batteries, and processes for manufacturing therefor. In this disclosure, the term cathode active material (also referred to as positive electrode active material) is referred to as CAM or CAM powder.

[0002] In particular, the present disclosure relates to a cathode active material (hereafter referred to as CAM) powder comprising a CAM fraction lithium (Li), nickel (Ni), manganese (Mn) and cobalt (Co). Such a CAM fraction is also referred hereunder as NMC (NiMnCo) CAM.

[0003] For instance, a NMC CAM comprises a Ni / (Ni+Mn+Co) ratio of at least 0.50 at% / at% (e.g., NMC532), or of at least 0.80 at% / at% (e.g., NMC811), or even of at least 0.90 at% / at% (e.g. NMC90.50.5). In the present disclosure, “at%” or “at.%” signifies atomic percentage. The at% or “atomic percent” of a given element means a percentage of atoms of said element among all atoms in a claimed composition. at% can be measured by inductively coupled plasma - optical emission spectrometry (hereafter referred to as ICP-OES). Equivalently at% can be equal to mol% or mol.%.

[0004] In the present disclosure, the terms “CAM” and “CAM powder” can be used interchangeably.

[0005] The term “comprising”, as used herein and in the claims, should not be interpreted as being restricted to the means listed thereafter; it does not exclude other elements or steps. It needs to be interpreted as specifying the presence of the stated features, integers, steps or components as referred to, but does not preclude the presence or addition of one or more other features, integers, steps or components, or groups thereof. Thus, the scope of the expression “a composition comprising components A and B” should not be limited to compositions consisting only of components A and B. It means that with respect to the present disclosure, the only relevant components of the composition are A and B. Accordingly, the terms “comprising” and “including” encompass the more restrictive terms “consisting essentially of” and “consisting of”.

[0006] The term “a cathode active material” as used herein and claimed is defined as a material which is electrochemically active in a positive electrode or cathode. By active material, it must be understood to be a material capable ofcapturing and releasing Li ions when subjected to a predetermined voltage change over a predetermined period of time. The NMC CAM according to the present disclosure is suitable to be used in Li-ions secondary batteries (hereafter referred to as LIBs). BACKGROUND

[0007] Along with the developments of (hybrid, in particular plug-in hybrid electric vehicles) electric vehicles (hereafter referred to as (H)EVs or PHEVs), it comes a demand for LIBs eligible for such applications and NMC CAMs are expected to be widely used materials as a component of CAM powder compositions, because of their high mass or volumetric energy density, and their higher (discharge) capacities at higher operating voltages when used in a battery.

[0008] In the framework of the disclosure, an electric vehicle may include any vehicle suitable for marine, air, aerospace and ground transportation.

[0009] Still, there is a need to further optimize electrochemical (hereafter referred to as EC) performances of CAMs.

[0010] Therefore, it is a first object of the present disclosure to provide a CAM powder composition including a NMC CAM and having improved cycle life as well as at least optimized or at best improved volumetric energy density (hereafter referred to as VED). SUMMARY OF THE DISCLOSURE CAM powders

[0011] The first object of the disclosure is achieved by providing a first cathode active material powder according to claim 1. FIRST ACTIVE MATERIAL

[0012] The first CAM of the disclosure comprises two fractions of CAM: - a first fraction of an olivine CAM that includes lithium (Li), iron (Fe), manganese (Mn), and phosphor (P). Such a CAM powder is also referred to as LFMP (LiFeMnP) CAM powder; and - a second fraction of NMC CAM that includes Li, Ni, Mn and cobalt (Co). The cobalt nickel manganese containing cathode active material of the 2ndfraction is a powder comprising particles that are standalone particles including at least one and at most twenty primary particles. This CAM powder is referred to as a semi monolithic powder or a powder having a semi monolithic morphology.

[0013] The term semi monolithic powder refer to a powder including single or secondary particles, each of the secondary particles consisting of no more than twenty primary particles. The number of primary particles constituting the secondary particles is determined based upon a scanning electron microscopy (hereafter referred to as SEM) image, for instance, in a field of view of at least 45 μm x at least 60 μm (i.e. of at least 2700 μm²), preferably of at least 30 μm x 100 μm (i.e. of at least 3000 μm²). The secondary particles in the image should be well distributed therefore avoiding overlap between secondary particles. This can be achieved by pouring a small amount of powder sample to the adhesive attached on the SEM sample holder and blowing air to remove the excess powder. In the context of the present invention primary particles are distinguished from each other in a SEM image by observing grain boundaries between the primary particles. A grain boundary is defined as the interface between two primary particles, for instance wherein the atomic planes of the two primary particles are aligned to different orientations and meet as a crystalline discontinuity.

[0014] Single particles are grain free and each of them consists of solely one standalone particle.

The term “precursor (of a CAM) or (CAM) precursor” as used herein and claimed is defined as a material suitable for manufacturing of a cathode material.

DETAILED DESCRIPTION OF THE DISCLOSURE EXPERIMENTAL ANALYSIS USED IN THE EXAMPLES

[0158] The following analysis methods are used in the Examples: A) Inductively Coupled Plasma Optical Emission Spectrometry (ICP- OES) measurements

[0159] The amount of Li, Ni, Co, Mn, Fe, P, D1, D4, D4’, and D4”, or for instance of: Li, Ni, Co, Mn, Al, Zr, B, Fe, P, Y, Nb, Sr, Ca, Mg, Si, and Ti in the positive electrode active material powder is measured with the ICP-OES method by using an Agilent ICP 720-ES (Agilent Technologies).

[0160] For the ICP analysis of bimodal and trimodal mixtures comprising CAM F1, CAM F2, CAM F3, and CAM F4, 0.5 grams of powder sample is dissolved in a mixture of 15 mL of high purity ammonium hydroxide solution (NH4OH ; at least 20 wt.% of NH4OH with respect to the total weight of solution) + 15 mL of high purity hydrochloric acid solution (at least 35 wt.% of HCl with respect to the total weight of solution) in an Erlenmeyer flask.

[0161] For the ICP analysis of CAM A (CAM F1, CAM F2, CAM F3, and CAM F4as well as CEX1.3, CEX1.4, CEX2.1, CEX2.2, CEX2.3 and CEX2.4), 2 grams of powder sample is dissolved into 10 mL of high purity hydrochloric acid solution (at least 35 wt.% of HCl with respect to the total weight of solution) in an Erlenmeyer flask.

[0162] The flask is covered by a glass and heated on a hot plate at 380 °C until complete dissolution of the precursor. After being cooled to room temperature, the solution of the Erlenmeyer flask is poured into a 250 mL volumetric flask. Optionally, the solution is filtered to remove residues and afterwards, the volumetric flask is filled with deionized water up to the 250 mL mark, followed by complete homogenization.

[0163] ICP-OES provides wt.% (or % w / w, or even wt%) of each element included in a material whose composition is determined by this technique.

[0164] Conversion from wt.% to at% or mol% is as follows: at% of a first element E1(Eat1) in a material can be converted from a given wt.% of said first element E1(Ewt1) in said material by applying the following formula,wherein Eaw1is a standard atomic weight (or molecular weight) of the first element E1, Ewtiis wt% of an ithelement Ei, Eawiis a standard atomic weight (molecular weight) of said ithelement Ei, and n is an integer which represents the number of types of all elements included in the material. B) Particle Size Distribution (PSD)

[0165] The particle size distribution (PSD) of a powder is measured by laser diffraction particle size analysis using a Malvern Mastersizer 3000 with a Hydro SV (for CAM F1as well as CEX1.3 and CEX2.1) or MV (for the other CAMs or mixtures) wet dispersion accessory after having dispersed each of the powder samples in a solvent. In order to improve the dispersion of the powder, sufficient ultrasonic irradiation and stirring is applied (unless explicitly indicated otherwise), and a surfactant is introduced. The sodium hexametaphosphate (10 %, 3 ml) solution was used as the surfactant. The solvent used to disperse each powder sample are: - isopropyl alcohol (99.5 % purity) for CAM F1(as well as CEX1.3 and CEX2.1) without ultrasonic irradiation; - deionized water for CAMs F2, F3, and F4(CEX2.1, 2.2, 2.3, 2.4) with ultrasonic irradiation; and - deionized water for EX1.1, 1.2, and 1.3, as well as EX2.1, 2.2, 2.3, 2.4, and 2.5, with ultrasonic irradiation and without using the surfactant.

[0166] D50 is defined as the particle size at 50 % of the cumulative volume% distributions, and a span (or SPAN) may be represented by D99 / D50 or span=(D90- D10) / D50, where D10, D50, D90 and D99 are defined as the particle size at 10 %, 50 %, 90 % and 99 % of the cumulative volume% distributions, respectively, obtained from the Malvern Mastersizer 3000 with Hydro SV or MV measurements. C) Pellet Density (PD)

[0167] The pressed density is measured as follows: 1.0~3.0 grams of powder is filled into a pellet die having an inner diameter "d" of 1.30 cm. A uniaxial load pressure of 207 MPa is applied to the powder in pellet die during 3 minutes and 30 seconds. After relaxing the load, the thickness "t (cm)" of the pressed powder is measured.

[0168] The pellet density (PD expressed in g / cm³) is then calculated as follows:D) Porosity

[0169] The porosity of a mixture of three CAMs, A, B, and C, are calculated by using the below equation: 100

[0170] The porosity is calculated with the above equation and by following the below steps: 1. A 1ststep of defining Ad(g / cc), Bd(g / cc), and Cd(g / cc), each representing a theoretical density of CAM A, B, and C, respectively, where each of the CAMs may be one of CAMs F1to F4. The theoretical densities were obtained from Published Crystal Structure Data (ICSD), for example, the theoretical density of CAM F1is 3.47 g / cc and of CAM F2, F3, and F4is 4.67 g / cc. 2. A 2ndstep of defining Aw(wt%) , Bw(wt%), and Cw(wt%), each representing a mass or weight fraction of each of CAM A, B, and C, respectively relative to the total amount of mixture. 3. In a 3rdstep, a specific volume of each CAM (in cc / g) is calculated by using the below equation:^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ ^^^^^^^^^^^^^^^^^^^^^^^^ ^^^^^^^^ ^^^^^^^^^^^^ ^^^^ =^^^^^^^^(^^^^^^^^%) ^^^^^^^^ (^^^^⁄ ^^^^^^^^ )4. In a 4st step, by summing these specific volumes, a total specific volume (cc / g) of the mixture is obtained. The reciprocal of the total specific volume (cc / g) gives the theoretical density (g / cc) of the CAM mixture. 5. In a 5thstep, the porosity is then calculated by using the below equation: wherein

[0171] The porosity value indicates how densely the CAM is packed. Pellet density measurement are provided in Section C) above.

[0172] For the porosity of a mixture of CAMs A and B, the theoretical density of the mixture is calculated with an equation:

[0173] For the porosity of a (standalone) of CAM A, the theoretical density of the material is calculated with an equation:, wherein, Aw= 100 wt%. E) Coin cell testing E-1) Coin cell preparation

[0174] For the preparation of a positive electrode, a homogeneous slurry that contains a mixture of : i) a positive electrode active material powder, ii) a conductive material such as carbon black (Li-435, Denka), iii) a binder (S5140, Solvay) – with a formulation of 92.7:3.3:4.0 by weight, and iv) with C5H9NO (N-Methyl-2-pyrrolidone) as solvent (NMP, Ashland) is prepared by mixing the above-mentioned i) to iv) components in a high-speed Thinky mixer. An electrode composite is prepared by spreading on one side of an aluminum foil or carbon-coated aluminum foil using a doctor blade coater followed by drying at 120˚C for 1 hour.

[0175] The loading level of the electrode is determined based on the electrode composite. For example, the loading level of the electrode composite comprising CAM A is calculated by using the below equation on a target areal capacity of 3 mAh / cm2:1000WA: weight fraction of CAM A which is 1 X (mAh / g) : 1C based theoretical discharge capacity in 4.3-2.5 V

[0176] For example of bimodal mixture, the loading level of the electrode composite comprising two CAMs, A, and B, is calculated by using the below equation on a target areal capacity of 3 mAh / cm2: 1000WA: weight fraction of CAM A in the total cathode active material in the mixture WB: weight fraction of CAM B in the total cathode active material in the mixture X (mAh / g): 1C based theoretical discharge capacity in 4.3-2.5 V Y (mAh / g): 1C based theoretical discharge capacity in 4.3-2.5 V

[0177] For example of trimodal mixture, the loading level of the electrode composite comprising three CAMs, A, B, and C, is calculated by using the below equation on a target areal capacity of 3 mAh / cm2: 1000WA: weight fraction of CAM A in the total cathode active material in the mixture WB: weight fraction of CAM B in the total cathode active material in the mixture WC: weight fraction of CAM C in the total cathode active material in the mixture X (mAh / g): 1C based theoretical discharge capacity in 4.3-2.5 V Y (mAh / g): 1C based theoretical discharge capacity in 4.3-2.5 V Z (mAh / g): 1C based theoretical discharge capacity in 4.3-2.5 V

[0178] For the theoretical capacity of CAM F1is 148 mAh / g, CAM F2is 220 mAh / g, and CAM F3and F4is 230 mAh / g.

[0179] After the loading level of the electrode is determined, the electrode composite is dried in an oven at 80~90 °C overnight. The dried electrode composite is then pressed using a calendaring tool to obtain a pressed electrode followed by punching using a 14 pi puncher, thereby obtaining a coin cell electrode. Then, the coin cell electrode is dried in a vacuum oven in order to completely remove the remaining solvent present in the positive electrode film.

[0180] A coin cell is assembled in an argon-filled glovebox. A 20 μm tri-layer Microporous Membrane (PP / PE / PP, polypropylene / Polyethylene / polypropylene) with pore size of 0.027 μm, 39 % porosity separator (Celgard 2320) is located between the positive electrode film and a piece of lithium foil used as a negative electrode. A mixture of LiPF6in EC / EMC (ethylene carbonate / ethyl methyl carbonate) 3:7 + 2 % LiBF4+ 5 % FEC (fluoroethylene carbonate) is used as electrolyte and is dropped between the separator and the electrodes. Then, the coin cell is completely sealed to prevent leakage of the electrolyte. Herein, the coin cell electrode is a foil coated with the slurry (i.e. a mixture constituted of the CAM powder, the conductive material, the binder, and the solvent) whereas the coin cell is constituted of the coated foil as positive electrode, the separator, and the lithium foil (anode). E-2) Coin cell testing Method

[0181] The testing method is a conventional “constant cut-off voltage” test. The conventional coin cell test in the present disclosure follows the schedule shown in Table 1. Each cell is cycled at 25 °C using a Toscat-3100 computer-controlled galvanostatic cycling station (from Toyo).

[0182] The prepared coin cell is charged with the current of 0.1C until 100 % of its theoretical capacity to measure the initial capacity. The coin cell is charged with a current of 0.1C up to 4.3 V and CC / CV mode (constant current-constant voltage) until a cut-off current of 0.05C is reached. The coin cell is discharged with a current of 0.1C in CC mode (constant current) down to 2.5 V. This step is done in 25 °C.

[0183] The discharge capacity after the 9th cycle (DQ9), and discharge capacity after the 36th cycle (DQ36) are measured in constant current mode (CC) at C rate of 0.1C in voltage range from 4.3 V to 2.5 V. The schedule uses a 1C current definition of 148 mAh / g in the 4.3 V to 2.5 V vs. Li / Li+ range. The first cycle is evaluated at 0.1C.

[0184] The capacity fading rate (QF01C) is obtained according to the following equation below:^^^^^^^^01^^^^(% / ^^^^^^^^^^^^^^^^^^^^) = 100100 27

[0185] The discharge capacity after the 10th cycle (DQ10), and discharge capacity after the 37th cycle (DQ37) are measured in constant current mode (CC) at C rate of 0.1C in voltage range from 4.3 V to 2.5 V. The schedule uses a 1C current definition of 148 mA / g in the 4.3 V to 2.5 V vs. Li / Li+ range. The first cycle is evaluated at 0.1C.

[0186] The capacity fading rate (QF1C) is obtained according to the following equation below: ^^^^^^^^1^^^^(%) = 100 ×�1 −^^^^^^^^37100 ^^^^^^^^� ×10Table 1.

[0187] Volumetric Energy Density is calculated by using the below equation, wherein DQ1 is discharge capacity of the 1st cycle and DV1 is averaged voltage of the 1st cycle from the coin cell testing: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ ^^^^^^^^^^^^^^^^^^^^^^^^ ^^^^^^^^^^^^^^^^^^^^^^^^^^^^ (^^^^ℎ⁄ ^^^^ )= ^^^^^^^^1 (^^^^^^^^^^^^^^^^ℎ^^^^^^^^^^^^^^^^ ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ ^^^^^^^^ 1^^^^^^^^ ^^^^^^^^^^^^^^^^^^^^,^^^^^^^^ℎ⁄ ^^^^ )× ^^^^^^^^1 ( ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ ^^^^^^^^^^^^^^^^^^^^^^^^^^^^ ^^^^^^^^ 1^^^^^^^^ ^^^^^^^^^^^^^^^^^^^^,^^^^)× ^^^^^^^^^^^^^^^^^^^^^^^^ ^^^^^^^^^^^^^^^^^^^^^^^^^^^^ (^^^^⁄ ^^^^^^^^ )RESULTS The present disclosure is further illustrated in the following examples and comparative examples.
