Title: Nonaqueous electrolyte secondary battery
Inventor: SASAKI JO
IPC: H01M4/13
Filed: 1998-11-17
Abstract: PROBLEM TO BE SOLVED: To restrain the decomposition reaction of cobalt oxide and a successive heat generation reaction to prevent the occurrence of thermorunaway even if a charger breaks down and causes overcharge by setting the specific surface area of a depolarizing mixture layer containing a positive electrode host substance in a certain range. SOLUTION: Whereas it is effective to reduce the specific surface area of a depolarizing mixture layer in order to prevent the thermorunaway of a positive electrode active material in an overcharge by reducing the contact area between the positive electrode active material and an electrolyte, because the reaction area of a positive electrode decreases as the contact area between the positive electrode active material and the electrolyte decreases, so that the current density of the positive electrode increases and overvoltage rises, the specific surface area of the depolarizing mixture layer needs to be set to a certain value or more in view of a charge-discharge characteristic.  Then, it is preferable that the specific surface area of the depolarizing mixture layer is adjusted in the range of 0.5-2 m2/g in order to satisfy two conditions such as the charge-discharge characteristic and safety. This nonaqueous electrolyte secondary battery that has large discharge capacity and improved in safety can be provided.
