Non-aqueous electrolyte battery and method of manufacturing same

摘要

A non-aqueous electrolyte battery comprising a positive electrode plate and a negative electrode plate of a light metal spirally wound with a separator in between and an electrolyte, wherein said separator is a microporous membrane or a non-woven cloth provided with a non-ion-permeable insulating band on at least one side and in a direction along the length of, and in the middle of the width of said separator, or said positive electrode plate comprises manganese dioxide as the cathodic active material and is provided with a band of a manganese lower oxide thereon at the middle and in a direction along the length of the electrode plate, having not only superior high-rate discharge performance but also high capacity and reliability without affecting prior art manufacturing processes used to produce the battery.
