Non-aqueous electrolyte rechargeable batteries

A non-aqueous electrolyte rechargeable battery resistant to the reflow temperature during reflow soldering, the non-aqueous electrolyte rechargeable battery comprising:

• a positive electrode having an active material comprised of an oxide of molybdenum;
• a negative electrode comprised of lithium and SiO;
• an electrolytic solution comprised of a material containing a supporting salt and resistant to the reflow soldering temperature;
• and a gasket comprised of a compound selected from the group consisting of a liquid crystal polymer, polyether ether ketone resin, polyether nitrile resin, and tetrafluoroethylene-perfluoroalkyl vinyl ether copolymer resin.
