Abstract
In a positive electrode of a non-aqueous electrolyte battery, at least one alkaline earth metal oxide selected from the group consisting of magnesium oxide, calcium oxide and barium oxide is dispersed between particles of an active substance for positive electrode, whereby a discharge capacity or recharge-discharge capacity of the non-aqueous electrolyte battery just after the preparation and after the storing at high temperature is improved.
