Putting the new cells together would produce as much electricity as conventional liquid electrolyte batteries, it said. Conventional liquid electrolyte batteries pose risks of catching fire due to chemical reactions inside, while solid electrolyte batteries are free from such risks, the team said.
The new technology would be able to downsize batteries and trim weight without taking any special safety measures. The team said it has been successful in test-producing 5,000- to 6,000-nanometer-thick batteries. A nanometer is one-1 billionth.
With the new technology, a suitcase-size lithium-ion battery for a vehicle could be made sharply smaller, the team said. Lithium-ion batteries are widely used for electric cars and hybrid motor vehicles, personal computers and mobile electronic devices.
