Abstract
This chapter reports that Li4Ti5O12 can offer a significant safety advantage over a graphite anode. Many researchers are attempting to develop high power, long life, and extremely safe lithium-ion chemistries with Li4Ti5O12 anodes for hybrid electric vehicles (HEVs) applications. The chapter focuses on the synthesis route to prepare nanostructured Li4Ti5O12. Bulk Li4Ti5O12 with micrometer-sized particles has low specific capacity and poor rate capability, due to the difficulty of lithium migration from the 8a to 16c sites in bulk materials. This issue can be resolved by taking advantage of the boundary effect of nanostructured materials. It has been consistently reported that lithium-ion batteries using nanostructured Li4Ti5O12 as the anode had extremely long cycle and calendar lives, high power capability, and unmatched safety characteristics. The data clearly show that this exemplary lithium-ion chemistry has already exceeded all the technical requirements needed.
