Recent Progress on Carbon Coated Lithium Titanate

Abstract

Being inherently safe and chemically compatible with the electrolyte, lithium titanate is considered alternatives to carbonaceous anodes in Li-ion batteries. Given the commercial success of the spinel lithium titanate, carbon coated lithium titanate, particularly in nano structured forms, have been fabricated and investigated for the applications. Nano structuring leads to increased reaction areas, shortened Li+ diffusion and potentially enhanced solubility/capacity. This paper reviews structural characteristics and electrochemical reactivity, along with synthetic approaches of carbon coated nanostructures and nano-composites based on lithium titanate, recently.
