Abstract:
A battery card adapted to be used with an electrical apparatus to be supplied power by said battery card comprising:two first planar attaching media respectively attaching thereto a first cathode material and a first anode material; a first planar separator separating said first attaching media and communicating said two first attaching media with each other simultaneously to form a first power-supplying cell; two second planar attaching media respectively attaching thereto a second cathode material and a second anode material; a second planar separator separating said second attaching media and communicating said second attaching media with each other simultaneously to form a second power-supplying cell electrically connected to said first power-supplying cell; a housing containing therein said first and said second power-supplying cells to form said battery card having a weight energy density larger than 40 watt-hours/kilograms and a volume energy density larger than 100 watt-hours/liter; two contacts mounted in an access of said housing and respectively electrically connected to said first and said second power-supplying cells for supplying power to said electrical apparatus through said two contacts; and a shutter moveably disposed on the peripheral edge of said housing to cover said access so as to shield said two contacts from exposure until said battery card is inserted into said electrical apparatus.
