Title:
NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY
Document Type and Number:
Japanese Patent JP2005332657
Kind Code:
A
Abstract:
To provide a non-aqueous electrolyte secondary battery in which a battery having a low voltage than the battery voltage after assembling without an initial discharge is formed and the deterioration of the battery performance brought about by heat treatment at the reflow soldering is small.
By containing a reduction metal at the positive electrode, the voltage of the battery immediately after assembling is reduced without a discharge process, and deterioration of battery characteristics due to heat treatment by a reflow soldering can be suppressed.
