A Comparison of High Capacity xLi[sub 2]MnO[sub 3]⋅(1−x)LiMO[sub 2] (M=Ni,Co,Mn) Cathodes in Lithium-Ion Cells with Li[sub 4]Ti[sub 5]O[sub 12]- and Carbon-Encapsulated Anatase TiO[sub 2] Anodes

The electrochemical performance of high capacity cathodes was evaluated in a lithium-ion cell configuration against - and carbon-encapsulated anatase, , anodes. The electrode composition that provides a rechargeable capacity of 250 mAh/g was selected for the study. cells operate with excellent reversibility, offering a superior energy density to (spinel/spinel) cells that are being developed for powering hybrid and plug-in hybrid (10 mile) vehicles. Carbon encapsulation of anatase did not improve the stability or cycle life of electrodes for ; cells steadily lose capacity on electrochemical cycling.
