摘要： A non-aqueous electrolyte cell which is provided with a non-aqueous electrolyte (20), an anode plate (34) and a cathode plate (36) which are in contact with the electrolyte (20), a separator (38) which is positioned between the plates (34 and 36), a first lead wire (18a) which is connected to the anode plate (34) at one end and extended to the outside at the other end, a second lead wire (18b) which is connected to the cathode plate (36) at one end and extended to the outside at the other end, and a sealing bag (14) which seals the plates (34 and 36), electrolyte (20), separator (38), and parts of the lead wires (18a and 18b). The bag (14) is provided with a hot-fusing resin layer (24), a metallic layer (22) provided on the outside of the layer (24), and an electrolyte blocking insulating layer (26). The insulating layer (26) is composed of nylon or ethylene-vinyl alcohol copolymer and has low miscibility with the non-aqueous electrolyte (20). Therefore, the sealing property of the bag (14) is improved, because the electrolyte (20) blocking property of the heat-sealed part (12) of the bag (14) is improved.

摘要： A non-aqueous electrolyte cell (10) which is provided with a non-aqueous electrolyte (20) which is a non-aqueous electrolytic medium, an anode plate (30) and a cathode plate (32) which are in contact with the medium (20), a first lead wire (18a) one end of which is connected to the plate (30) and the other of which extends to the outside, a second lead wire (18b) one end of which is connected to the plate (32) and the other of which extends to the outside, and a sealing bag (14) in which the plates (30 and 32), electrolyte (20), and parts of the wires (18a and 18b) are sealed by heat-sealing. At least heat-sealed part (12) of the bag has a layer made of maleic-acid-modified polyolefin. Maleic-acid-modified polyolefin has a low moisture absorption and a low compatibility with the electrolyte (20). Therefore, the bag (14) has a high sealability because the non-aqueous electrolyte and steam blocking properties of the bag (14) are improved.

摘要翻译： 一种非水电解质电池（10），其具有作为非水电解质介质的非水电解质（20），与介质接触的阳极板（30）和阴极板（32） （20）;第一引线（18a），其一端连接到所述板（30），另一端延伸到外部;第二引线（18b），其一端连接到所述板（ （30,32），电解液（20）以及电线（18a，18b）的一部分通过热封而密封的密封袋（14） 。 至少袋的热封部分（12）具有由马来酸改性聚烯烃制成的层。 马来酸改性聚烯烃具有低吸湿性和与电解质（20）的低相容性。 因此，由于袋子14的非水电解质和蒸汽阻挡性能得到改善，所以袋子14具有高密封性。
