Abstract:
A method of manufacturing a hydrogen lithium titanate compound, the method comprising the steps of:bringing a lithium titanate compound into contact with an acid, the lithium titanate expressed by a general formula Li.sub.y Ti.sub.z O.sub.4 where 0.8.ltoreq.y.ltoreq.2.7 and 1.3.ltoreq.z.ltoreq.2.2; andsubstituting protons for lithium ions in said lithium titanate compound to form hydrogen lithium titanate, the hydrogen lithium titanate expressed by a general formula H.sub.x Li.sub.y-x Ti.sub.z O.sub.4, where y.gtoreq.x>0, 0.8.ltoreq.y.ltoreq.2.7 and 1.3.ltoreq.z.ltoreq.2.2.
