Properties of high surface area titania by sol-gel process

Abstract

Titania was synthesized in the form of microparticle by sol-gel method. The size of particles was about 4 nm. Addition of acetylene black in synthesis allowed us to obtain titania/carbon composite materials. They were tested as an electrode for lithium secondary battery. They possessed potential around 2 V (vs.Li⁺/Li) and exhibited specific capacity above 100 mAh/g even under large discharge current of 10 A/g (titania weight is used for standardization).
