POWER STORAGE ELEMENT AND POWER SUPPLY MODULE

摘要

PROBLEM TO BE SOLVED: To secure the safety against overcharge and the like.SOLUTION: A nonaqueous electrolyte secondary battery 1 comprises: a power generation element 11; a housing container constituted of a container main body 10 housing the power generation element 11, and a lid part 20; electrode members 50 of a positive electrode and a negative electrode connected to the power generation element 11; and a short-circuit mechanism including conductive metal films 31 short-circuiting the electrode members 50 of the positive electrode and the negative electrode. The nonaqueous electrolyte secondary battery 1 has a resistor provided on a short-circuit path between the electrode member 50 of the positive electrode and the electrode member 50 of the negative electrode, and constituted of a resistive element 33 suppressing current flowing between terminals and a contacted plate 32.
