Abstract

The invention relates to a doped BaSO 4 Anode material for sodium ion battery and preparation method thereof, comprising the following steps: (1) one-step hydrothermal method for preparing SnO 2 Material; (2) SnO 2 The material was dissolved in deionized water, dilute sulfuric acid solution and Ba(OH) 2 solution, to achieve BaSO 4 Doped SnO 2 Composite material; (3) ZnS / C composite material prepared by carbothermal reduction method: take zinc salt and sulfur source as raw materials and dissolve them in deionized water, and obtain a ZnS material precursor after the reaction, then dissolve the precursor in deionized water, add Organic carbon source, stir until the water evaporates completely, then place in an inert atmosphere and roast; (4) BaSO 4 Doped SnO 2 The composite material and the ZnS / C composite material are mixed in proportion. The doping BaSO that the inventive method makes 4 The prepared electrode material can meet the performance requirements of the negative electrode material of the sodium ion battery, and has a high initial capacity, a good specific capacity, a high first Coulombic efficiency and ideal cycle stability, making the sodium ion battery in the energy storage system status has been elevated.

Description

A doped BaSO 4 Anode material for sodium ion battery and preparation method thereof technical field The present invention relates to battery material technical field, be specifically related to a kind of doped BaSO 4 Na-ion battery anode material and its preparation method. Background technique As an important means of energy storage and conversion, secondary battery technology is widely used in people's daily life, industrial production, military The fields of national defense and aerospace have a very wide range of applications. Therefore, secondary batteries occupy a large position in the field of new energy. vital position. At present, lithium-ion batteries, the fastest-growing and most mature technology in the secondary battery system, are widely concerned. Note. However, the lithium resources in the earth's crust are very limited, and people's consumption of lithium resources is increasing year by year. It has stimulated the continued increase in li...
