A thin rechargeable lithium battery having a battery main body enclosed between sealing members (a) and (b), at least sealing member (a) having a concave portion that extends to either side from a central position so as to have a peripheral collar portion (a-i) which surrounds the concave portion, sealing member (b) having a peripheral collar portion (b-i) corresponding to the collar portion (a-i) of sealing member (a) and the two sealing members (a) and (b) being opposingly arranged such that the face of said concave portion of sealing member (a) faces sealing member (b) through the battery main body, wherein collar portions (a-i) and (b-i) are mutually welded, and either sealing member (a) or (b) is provided with a power output terminal having electrical continuity with the battery main body and an insulating portion for insulating said terminal.
A rechargeable lithium battery which comprises a pair of a sealing member (a) and a sealing member (b) and only a single battery main body which comprises a cathode, an anode, and an ion conductor, wherein said single battery main body is enclosed between said pair of said sealing member (a) and said sealing member (b), at least said sealing member (a) having a concave portion such that said concave portion is extended to either side of said sealing member (a) from a central position of said sealing member (a) so as to have a peripheral portion which surrounds said concave portion, and said sealing member (a) and said sealing member (b) being arranged to oppose to each other such that the face of said concave portion is faced to said sealing member (b) through said single battery main body, characterized in that said sealing member (a) has a peripheral collar portion (a-i) at said peripheral portion and said sealing member (b) has a peripheral collar portion (b-i) at a region thereof corresponding to said peripheral portion, and wherein said peripheral collar portion (a-i) and said peripheral collar portion (b-i) are mutually welded, and said sealing member (a) is provided with a power output terminal having electrical continuity with said cathode, a power output terminal having electrical continuity with said anode, and an insulating portion for insulating said power output terminals.
