The graphite based materials still occupy the mainstream of the LIB anode materials. While in recent years, the R&D of novel anode materials are concerned by the industry, Li4Ti5O12 (LTO) is a significant direction.
The electrode potential of LTO is 1.55V (vs. lithium), the theoretical capacity is 175mAh/g, the actual capacity is 150 ~ 160mAh/g. LTO’s crystal form does not change when Lithium inserting in or escaping out, the volume change is less than 1%, so called "zero-strain material”. These features make it a better cycling performance than the carbon anode.
LTO has the particular advantages comparing other anode materials. As an anode material for power lithium-ion battery, it has a huge value and potential for commercial applications.
2012 China LIB Anode Materials Conference will be held in August 23-25 in Qingdao, Shandong Province. The expert from Clariant/Sud-Chemie will deliver a presentation on the R&D updates on LTO based Anode Materials.
