Study on sodium ion battery with high first coulombic efficiency and cycle stability
Sodium-ion batteries have the advantages of high safety and low cost, which are expected to be applied to large-scale energy storage in smart grids. As the anode material of sodium ion battery, SnS2 has a high theoretical specific capacity, but its first coulombic efficiency is low, which seriously hinders its practical application.

The selection and preparation of anode materials is the ceiling that limits the application of lithium-ion batteries, and the more popular graphite anodes and ternary lithium-ion power batteries at this stage can not meet the urgent needs of emerging electronic products for high energy density batteries. As an active anode material for advanced lithium-ion batteries, silicon has attracted much attention because of its high theoretical capacity. However, the rapid capacity fading of silicon-based anode materials still hinders the reversible utilization of silicon-based anode materials due to the huge volume changes of silicon during cycling.
Graphite-like silicon nanospheres (Si @ C) have a high specific capacity, but in the process of lithiation, the internal mechanical stress of the silicon ball will cause the silicon ball to expand rapidly and destroy the external network coating, so it has not been widely used. Recently, PicoFemto®Helping Professor Wang Xi of Beijing Jiaotong University and researcher Chen Shimou of the Institute of Process of Chinese Academy of Sciences to make new discoveries in the research of Si @ NG-based lithium ion battery anode materials. The relevant research results are published in the international journal Nano Energy (IF = 15.46) under the title of "Stress-relieving defects enable ultra-stable silicon anode for Li-ion storage.
