Patent ID: 10276868

Abstract:
A non-aqueous rechargeable battery has a non-aqueous electrolyte and positive and negative electrodes capable of intercalating and deintercalating lithium ions. The positive electrode contains a lithium transition metal oxide expressed by Li2-xNiαM1βM2y O4-ε,where 0.50<α<=1.33, 0<=β<0.67, 0<=γ<=1.33, 0<=ε<=1.00, M1 is at least one of Co, Al and Ga, and M2 is at least one of Mn, Ge, Sn and Sb, and x reversibly varies within a range of 0<=x<=2 by intercalating and deintercalating lithium ions. A resistance of the positive electrode when SOC is 0% is not less than twice of that when SOC is not less than a predetermined SOC. A capacity of the negative electrode is not less than 1.1 times of that of the positive electrode.
