New alternative oxides used as cathodes in Batteries

Using cheap and environment benign alternative oxides as cathodes in batteries is the current trend to give cheap, environmently benign and high energeytic cathode material instead of the commerecial one of high excepensive, toxic and unstable LiCoO2 used in lithium ion batteries. Using alpha-manganese dioxides of the tunnel structure with their modifications by using Sn and Co as dopants as cathodes in alkaline batteries.
