VANADIUM SOLID SALT BATTERY

PROBLEM TO BE SOLVED: To provide a vanadium solid salt battery that can enhance sealing performance and reduce the internal resistance.SOLUTION: A vanadium solid salt battery includes a first electrode material and a second electrode material which contain vanadium, a power generation unit containing a diaphragm for partitioning the two electrode materials and electrolytic solution, a first sheet which is in contact with the first electrode member, a first flat-plate type conductive material that is in surface contact with the first sheet, a second sheet which is in contact with the second electrode, a second flat-plate type conductive material that is in surface contact with the second sheet, a resin material covering the first flat-plate type conductive material and the second flat-plate type conductive material, and an adhesive portion which sticks the periphery of the resin material so as to pressure-weld the first flat-plate type conductive material, the first sheet, the power generation unit, the second sheet and at least a part of the second flat-plate type conductive material while the diaphragm is sandwiched between the first sheet and the second sheet. The first flat-plate type conductive material, the first sheet, the power generation unit, the second sheet and the second flat plate type conductive material are housed in the resin material.SELECTED DRAWING: Figure 1 【課題】封止性を向上するとともに、内部抵抗を低減したバナジウム固体塩電池を提供する。【解決手段】バナジウムを含有する第１の電極材及び第２の電極材と、２つの電極材を区画する隔膜と、電解液とを含む発電ユニットと、第１の電極材と接触する第１のシートと、第１のシートと面接触する第１の平板状導電材と、第２の電極材と接触する第２のシートと、第２のシートと面接触する第２の平板状導電材と、第１の平板状導電材及び第２の平板状導電材を覆う樹脂材と、第１のシートと第２のシートの間に隔膜を挟んで、第１の平板状導電材、第１のシート、発電ユニット、第２のシート及び第２の平板状導電材の少なくとも一部を圧接するように、樹脂材の周囲を接着した接着部を備え、第１の平板状導電材、第１のシート、発電ユニット、第２のシート及び第２の平板状導電材を樹脂材の内部に収容したバナジウム固体塩電池に関する。【選択図】図１
