NONAQUEOUS ELECTROLYTIC CELL AND ITS MANUFACTURING METHOD, AND POSITIVE ELECTRODE ACTIVE MATERIAL AND ITS MANUFACTURING METHOD

摘要

The present invention relates to a nonaqueous electrolyte battery comprising: a cathode including a positive active material; an negative including a negative active material and a nonaqueous electrolyte, wherein assuming that the first charging capacity of the positive active material per gram is Cc ÄmAh/gÜ, the weight of the positive active material is Cw ÄgÜ, the first charging capacity of the negative active material per gram is Ac ÄmAh/gÜ, the first discharging capacity is Ad ÄmAh/gÜ and the weight of the negative active material is Aw ÄgÜ, the value of X Ä%Ü represented by a formula 16 is located within a range expressed by 20 ≤ X ≤ 50. (Ac - Ad) x Aw DIVIDED Cc x Cwx 100 = X Thus, the deterioration of a capacity due to charging and discharging cycles is suppressed.
