NONAQUEOUS ORGANIC ELECTROLYTE SECONDARY CELL

Title:

NONAQUEOUS ORGANIC ELECTROLYTE SECONDARY CELL

Document Type and Number:

WIPO Patent Application WO/2014/021014

Kind Code:

A1

Abstract:

Provided is a nonaqueous organic electrolyte secondary cell in which the counter charge capacity ratio (A/C) of the positive electrode and negative electrode as represented by the formula is set at 1.10 to 1.35 inclusive. A/C = β× (negative electrode charge capacity × α)/(positive electrode charge capacity × η × τ) (In the formula, α is the electrode surface area coefficient as represented by the negative electrode surface area/positive electrode surface area, α > 1.0, β is a design coefficient, 0.85 <β < 1.15, η is the charge-discharge efficiency ratio as represented by (charge-discharge efficiency at 25ºC)/(charge-discharge efficiency at 55ºC), and τ is the temperature characteristic coefficient as represented by (charge capacity at 55ºC)/(charge capacity at 25ºC).
