Patent ID: 8192871

Claim:
A nonaqueous lithium battery comprising: a positive electrode active material comprising a lithium-containing oxide capable of inserting and detaching lithium ions; a negative electrode active material comprising a carbon material capable of inserting and detaching lithium ions; a negative electrode conductive material; and a nonaqueous electrolytic solution containing lithium ions, wherein a coating of a compound derived from vinylene carbonate is formed on a surface of the negative electrode active material after initializing charging, wherein a battery capacity of the lithium battery is not greater than 10 Ah, and wherein an amount of the negative electrode active material is A, an amount of the negative electrode conductive material is B, a specific surface area of the negative electrode active material is X (m 2 /g), a specific surface area of the negative electrode conductive material is Y (m 2 /g), and an additive amount C (g/m 2 ) of vinylene carbonate is in a range calculated from an equation: 0.0058 ≦ C ⁡ ( g ) ( A · X + B · Y ) ⁢ ( m 2 ) ≦ 0.0115 .
