VANADIUM SOLID SALT BATTERY

PROBLEM TO BE SOLVED: To provide a vanadium solid salt battery which is enhanced in sealability, and reduced in internal resistance.SOLUTION: A vanadium solid salt battery comprises: a power generation unit including first and second electrode materials including vanadium, a diaphragm for partitioning the two electrode materials from each other, and an electrolytic solution; a first sheet in contact with the first electrode material; a first tabular conductive material in surface contact with the first sheet; a second sheet in contact with the second electrode material; a second tabular conductive material in surface contact with the second sheet; a pair of third sheets for covering the first and second tabular conductive materials; and a bonding portion where the pair of third sheets are bonded together at their peripheral portions so that the first tabular conductive material, the first sheet, the power generation unit, the second sheet and the second tabular conductive material are at least partially put in press-contact together with the diaphragm sandwiched between the first and second sheets. Thus, the first tabular member, the first sheet, the power generation unit, the second sheet and the second tabular member are housed inside between the pair of third sheets in the vanadium solid salt battery. 【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第３のシートと、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、第３のシートの周囲を接着した接着部を備え、第１の平板状部材、第１のシート、発電ユニット、第２のシート及び第２の平板状部材を第３のシート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
