NONAQUEOUS SECONDARY BATTERY, BATTERY PACK, POWER SUPPLY SYSTEM, AND ELECTRICAL DEVICE
First Claim
1. A nonaqueous secondary battery, comprising:
- a negative electrode containing at least one of a material capable of reversely inserting and extracting lithium and metal lithium as a negative electrode active material;
a positive electrode containing lithium as a positive electrode active material;
an electrolyte; and
a heat resistant member provided between the negative electrode and the positive electrode and permeable to lithium ions while having heat resistance,wherein in a case where a set voltage preset to a voltage lower than a voltage at which the electrolyte starts to decompose is applied between the negative electrode and the positive electrode, deposited metal is bridged between the negative electrode and the positive electrode according to the set voltage.

Abstract
A nonaqueous secondary battery includes a negative electrode plate 303 containing a negative electrode active material 324 capable of reversely inserting and extracting lithium, a positive electrode plate 301 containing lithium as a positive electrode active material 322, an electrolyte, a porous protective membrane 325 provided between the negative electrode plate 303 and the positive electrode plate 301 and permeable to lithium ions while having heat resistance, and a concave portion 352 in which growth of deposited metal, which is formed according to a set voltage Vs, is controlled in such a manner that the deposited metal is bridged between the negative electrode plate 303 and the positive electrode plate 301 when the set voltage Vs is applied between the negative electrode plate 303 and the positive electrode plate 301.
