A vehicle battery using “an inventive metal particulate anode” and a “bifunctional air electrode” may be recharged either by circulating the electrolyte containing the zinc particles and passing reverse current through them to recharge the battery, or the particles may be pumped out and replaced with previously recharged particles. This allows an electric vehicle to refuel at a zinc particle filling station. U.S. Patent # 5,441,820 describes this development and is available for licensing fromTechnology…

Click on the links to see these new developments. Announcement of a ‘Self-Charging’ battery The Inventions Submission Corporation (ISC), of Pittsburgh PA has announced that two Fort Wayne IN inventors have created a self-charging replacement for rechargeable batteries. The invention “recharges without the use of special equipment or electrical current and can be produced in all standard battery sizes.” Another entry to the “self-charging” field is shown in a US Patent Office Patent Application Publication…

Battery energy does not always remain quietly stored in the battery. Sometimes you must get that energy out in a hurry. Short bursts of power are required, for instance, when starting an automobile on a cold morning. Cold cranking requires high current from the battery. When you turn on the viewing screen of a digital camera, you also demand high current output from the camera’s battery. The power used comes from stored energyDuring every interval…

Our history of batteries begins with the Baghdad battery Why was a battery required 2000 years ago? In June, 1936, workers constructing a new railway near the city of Baghdad uncovered an ancient tomb. Relics in the tomb allowed archeologists to identify it as belonging to the Parthian Empire.
