Embodiment 1

[0027] In order to achieve the above purpose, the preparation steps of specific amorphous O-doped BN nanosheets are:

[0028] 50 mg of amorphous graphene-like CuB 23 The nanosheets were added to 50 mL of [BMIM]Cl solution to form a suspension.

[0029] 1) Add 2 mmol of Na 2 TiO 3 and 2 mmol EuCl 3 Add to 80mL of 0.2 M sodium tartrate solution, and form a homogeneous suspension under ultrasonic conditions.

[0030] 2) Transfer the suspension to a 100 mL Teflon-lined reactor and keep it at 160 °C for 12 h.

[0031] 3) Use a centrifuge to separate the product sea urchin-like NaEuTiO 4 Nanowires.

[0032] 4) The obtained product was washed three times with deionized water and dried in an oven.

[0033] Urchin-shaped NaEuTiO of the present invention 4 Properties of nanowires:

[0034] We will elucidate the synthesis mechanism of this material, from figure 1 a It can be seen that amorphous NaEuTiO was obtained after 0.5h 4 , and the sample consisted of many small irregula...

Abstract

The invention discloses a preparation method of a sea urchin-like NaEuTiO4 nanowire. The preparation method is characterized in that a hydrothermal method is adopted, and Na2TiO3 powder and EuCl3 powder are added into a sodium tartrate solution for carrying out high-pressure hydrothermal reaction: Eu<3+>-Tart<+>+H2O+Na<+>+TiO3<2-> is equal to NaEuTiO4+H2Tart; the sea urchin-like NaEuTiO4 nanowireis successfully synthesized under the conditions of high temperature and high pressure and can be used as a precursor for synthesizing LiEuTiO4. The material has a unique structure and ion exchange capacity, and can completely and rapidly exchange lithium ions or hydrogen ions. The material has a wide application prospect in the field of lithium battery and especially in NaEuTiO4 lithium battery materials.

Description

technical field [0001] The present invention relates to NaEuTiO 4 In the field of nanomaterial technology, especially related to sea urchin-like NaEuTiO 4 Methods of preparing nanowires. Background technique [0002] Rechargeable lithium-ion batteries (LIBs) are widely used in portable electronic devices. However, the application of lithium batteries to electric vehicles (EVs) or hybrid electric vehicles (HEVs) requires high safety in addition to improved performance and long service life. Unfortunately, since the Li-ion potential is 0.1V (vs. Li + / Li), current commercial graphite anodes have difficulty meeting these requirements, which can lead to electroplating and thus safety concerns. [0003] Multiple alternative anode materials with operating potentials around 1 V have been developed in an attempt to alleviate this problem, with the goal of avoiding lithium plating while maintaining cell voltage. Among them, the materials with excellent performance are LiEuTiO 4...
