Battery pack and charge and discharge method of battery pack

摘要: PROBLEM TO BE SOLVED: To provide a battery pack and charge discharge method of the long life excellent energy density, capable temperature control batteries by discharge, hardly affected surrounding environments. SOLUTION: The 30 with plurality flat secondary 10 stacked is provided heat exchanger plates 7 each having principal surface in contact so as to exchange forming battery/heat exchanging plate assembly combination battery, at least one thermoelectric conversion element 31 fitted side face assemblies assemblies, an outer package member 38 insulating layer element. has anode active material cathode area which entropy variation ΔS total reaction under normal atmospheric pressure becomes endothermic.
