Enhanced Rate Performance of Li4Ti5O12 Anode for Advanced Lithium Batteries

With the increasing development of energy storage, searching a suitable anode comes to be one of the hottest issues in lithium ion batteries. Li4Ti5O12 owns the advantages of long discharge plateau, superior safety and so on, but suffering the low electron conductivity. In this work, a facile method with NF3 for the fluorination of Li4Ti5O12 is applied. Via this method, the enhanced rate performance and larger specific capacity of the fluorination Li4Ti5O12 are obtained. All these results will provide an applicable modification of Li4Ti5O12 materials, which can contribute a lot to the development of lithium ion batteries.
