| 20110281153 | BATTERY - A battery includes at least one positive pole film, at least one negative pole film, at least one isolation membrane, a positive pole clamp, a negative pole clamp, a positive conducting pole, a negative conducting pole, a shell and an electrolyte. The positive pole film includes a positive pole material film and a bare aluminum zone, and the negative pole film includes a negative pole material film and a bare copper zone. The negative pole material film overlaps the positive pole material film, and the isolation membrane is disposed between the pole films to isolate the negative pole material film from the positive pole material film. The positive pole clamp clamps the bare aluminum zone, and the negative pole clamp clamps the bare copper zone. The positive conducting pole is welded to the positive pole clamp, and the negative conducting pole is welded to the negative pole clamp. | 11-17-2011 |
| 20110260540 | BACKUP POWER SUPPLY FOR A VEHICLE - The backup power supply of the present invention is adapted for a vehicle, which has a power system. The backup power supply includes a motor electronic appliance and a battery. The motor electronic appliance is installed in the vehicle and electrically connects to the power system of the vehicle. The battery electrically connects to the motor electronic appliance, such that the battery can receive electric power from the power system or can supply electric power to the power system. As such, the backup power supply supplies backup power to the power system during the replacement of the motor lead-acid battery. | 10-27-2011 |
| 20100003587 | FOLDING SECONDARY BATTERY - A folding secondary battery includes a folded body mounted in a housing filled with an electrolyte solution. A positive electrode, two negative electrodes and two isolation films respective sandwiched between the positive electrode and one of the negative electrodes are laminated and folded to form the folded body with a zigzag shape. Films of positive active material are spacedly arranged on opposite sides of the positive electrode in a pair manner. On one side of the negative electrode facing the positive electrode, films of negative active material are spacedly arranged corresponding to the films of positive active material. The positive electrode and negative electrode are folded at a location between two of the films of positive active material and two of the films of negative active material respectively, thereby preventing detachment of the films due to fold and a deformation phenomenon under charging. | 01-07-2010 |
