Title:
BATTERY
Document Type and Number:
Japanese Patent JP2006228601
Kind Code:
A
Abstract:

To provide a battery capable of suppressing drop in discharge capacity.

A polymer containing tertiary amine such as 4-vinyl pyridine/styrene copolymer and at least one kind of compound having the characteristic of tertiary amine is contained in the battery. Even if a free acid is generated in an electrolyte, the free acid is effectively removed with the unpaired electron of nitrogen contained in the polymer, and drop in discharge capacity is suppressed. By using a cyclic carbonate ester derivative having a halogen atom in the electrolyte, drop in the discharge capacity is more suppressed.
