高温固相法一步合成碳包覆钛酸锂
One step synthesis of carbon coated lithium titanate by high temperature solid state method
摘要
Abstract
The Li4Ti5O12/C material was synthesized by high temperature solid state with Li2CO3,TiO2 and sucrose (C12H22O11) as raw material,with deionized water as mixed solvent,with argon as protective gas.The crystalline structure,morphology and electrochemical performances of the sample were investigated by X-ray diffraction,scanning electron microscope and charge discharge test.The results show,compared with lithium titanate synthesized by traditional high temperature solid state,the particle size of carbon coating lithium titanate is obviously smaller.The average particle size of the primary particle is only 82 nm.The discharge specific capacity of carbon coating lithium titanate is obviously higher,and the discharge specific capacity are 171.3,162.3,157.8 mAh/g by the charge-discharge rate of 0.1 C,1 C,5 C respectively,and the capacity retention rate is 100％ after 20 cycles.关键词
