Description

Technical Field

[0001] This invention relates to a battery, and more particularly to a battery with an improved positive electrode material. Background Technology

[0002] Generally, most modern batteries suffer from excessive expansion of the positive electrode after multiple charge-discharge cycles, which can shorten battery life or even cause short circuits. For example, when graphite is used as the positive electrode material, active materials in the battery intercalate between the graphite layers to generate electricity. However, after sufficient intercalation of active materials, the positive electrode is prone to expansion. This expansion puts stress on the separator, making it susceptible to conduction with dendrites formed on the negative electrode plating, thus shortening battery life or even causing short circuits. Therefore, improving the expansion problem to increase battery life and avoid short circuits remains a challenge. Summary of the Invention

[0003] This invention provides a battery that can improve battery capacity while reducing swelling, increasing battery life, and preventing short circuits.

[0004] The present invention discloses a battery comprising an electrolyte and a positive electrode. The electrolyte is configured to generate live organisms. The battery generates electricity by the live organisms being intercalated into the crystal structure of the positive electrode.

[0005] In one embodiment of the present invention, the battery described above is formed by inserting living material into the lattice structure of the positive electrode to form an alloy state.

[0006] In one embodiment of the present invention, the material of the positive electrode is aluminum titanate (ATO).

[0007] In one embodiment of the present invention, the aluminum titanate accounts for at least 50% of the positive electrode.

[0008] In one embodiment of the present invention, the above-mentioned crystal structure is a titanium dioxide plate titanium (TiO2) ore crystal lattice.

[0009] In one embodiment of the present invention, the battery lifespan is at least greater than 50 cycles.

[0010] In one embodiment of the present invention, the expansion thickness of the above-mentioned positive electrode is at least less than or equal to 100 micrometers.

[0011] In one embodiment of the present invention, the coefficient of thermal expansion of the above-mentioned positive electrode material is at least less than 1 x 10⁻⁶. -6 / ℃.

[0012] In one embodiment of the present invention, the battery is an aluminum battery.

[0013] In one embodiment of the present invention, the aforementioned active substance is aluminum ions (Al).3+ ).

[0014] Based on the above, the present invention selects a positive electrode material and uses a positive electrode with a lattice structure to reduce the expansion phenomenon after the intercalation of living organisms and to store ions to generate electricity. Therefore, it can improve the expansion problem, increase battery life and avoid short circuits while increasing battery capacity.

[0015] To make the above features and advantages of the present invention more apparent and understandable, specific embodiments are described below in conjunction with the accompanying drawings. Attached Figure Description

[0016] Figure 1 This is a schematic diagram of the material structure of the positive electrode of a battery according to an embodiment of the present invention. Detailed Implementation

[0017] Reference will now be made in detail to exemplary embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same element references are used in the drawings and description to denote the same or similar parts.

[0018] To facilitate a better understanding of the invention, specific embodiments are provided below as examples of how the invention can indeed be practiced. For clarity, numerous practical details will be described in the following description. However, it should be understood that these practical details are not intended to limit the invention. That is, in some embodiments of the invention, these practical details are not essential.

[0019] Unless otherwise defined, all terms used herein (including technical and scientific terms) have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0020] Figure 1 This is a schematic diagram of the material structure of the positive electrode of a battery according to an embodiment of the present invention. Please refer to... Figure 1 The battery of this embodiment includes an electrolyte and a positive electrode. The electrolyte is configured to generate live organisms. The battery generates electricity by intercalating the live organisms into the lattice structure 100 of the positive electrode. Accordingly, by selecting a positive electrode material and using a positive electrode having the lattice structure 100, this embodiment reduces the expansion phenomenon after live organism intercalation and can store ions to generate electricity. Therefore, it can improve the expansion problem, increase battery life, and avoid short circuits while increasing battery capacity. Furthermore, the battery can generate electricity by intercalating the live organisms into the lattice structure of the positive electrode to form an alloy state. In other words, the battery of this embodiment does not generate electricity by intercalating the live organisms into the graphite layer spacing.

[0021] In some embodiments, the positive electrode material is aluminum titanate (CAS: 12004-39-6), and its crystal structure is a titanium dioxide diatomite lattice. Since the titanium dioxide diatomite lattice in aluminum titanate can effectively provide power during battery charging and discharging, and no significant expansion occurs on the positive electrode, aluminum titanate as the positive electrode material has the ability to improve positive electrode expansion and increase power output. For example, when the positive electrode material is aluminum titanate, the battery life is at least greater than 50 cycles. For instance, when the positive electrode material is graphite, the lifespan is less than 50 cycles, while when aluminum titanate is used as the positive electrode material, the lifespan can be increased to 100 cycles, thus improving it by approximately 100%. Furthermore, the expansion thickness of the positive electrode is at least less than or equal to 100 micrometers. For example, when the positive electrode material is graphite, the expansion thickness is approximately 375 micrometers, while when aluminum titanate is used as the positive electrode material, the expansion thickness is approximately 100 micrometers. On the other hand, when the positive electrode material is changed from graphite to aluminum titanate, the battery capacity can be increased from 48 milliampere-hours (mAh) to 51 milliampere-hours. Therefore, the battery expansion, lifespan and capacity are indeed improved. However, the present invention is not limited to this. The battery lifespan and the thickness of the positive electrode depend on the choice of positive electrode material. As long as the battery generates battery capacity by inserting living material into the lattice structure of the positive electrode, it is within the protection scope of the present invention.

[0022] In some embodiments, the coefficient of thermal expansion of the positive electrode material is at least less than 1 x 10⁻⁶. -6 / ℃, which means that the material of the positive electrode can be a material with a low coefficient of thermal expansion. When it reacts with anions, its structure does not actually expand or contract, that is, its shape is not easily changed. Therefore, while storing ions to generate electricity, the positive electrode will not expand, thus extending the battery cell life. However, the present invention is not limited to this.

[0023] In some embodiments, aluminum titanate accounts for at least 50% of the positive electrode (in a mixed form) to obtain a better intercalation effect, but the present invention is not limited thereto.

[0024] In some embodiments, the battery is an aluminum battery, therefore the active organism is aluminum ions (Al). 3+ The battery generates electricity by forming an alloy state between aluminum ions and aluminum titanate lattice. However, the present invention does not limit the type of battery. As long as the positive electrode material of the battery has the same mechanism as the present invention, it is within the scope of protection of the present invention.

[0025] It should be noted that other unspecified components in the battery (such as the negative electrode, separator, and electrolyte) and specifications should be obtained by a person skilled in the art based on any content that covers the spirit and scope of the appended claims.

[0026] In summary, by selecting a positive electrode material and using a positive electrode with a lattice structure, this invention reduces the expansion phenomenon after the intercalation of living organisms and can store ions to generate electricity. Therefore, it can improve the expansion problem, increase battery life and avoid short circuits while increasing battery capacity.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
