Israel21C is reporting the the Department of Electrical Engineering - Systems at Tel Aviv University have come up with a "nano-battery technology for fast charge/discharge batteries" which they point out (due to recent events) "eliminates fire hazards associated with current lithium-based batteries".
comprises a substantial number of miniature batteries, about 30,000 on an area as small as one square centimeter, all connected in parallel. This architecture provides a high output of electrical power,
The basic unit is a 50 micron diameter battery - about the thickness of a strand of hair.
it's likely that safe and powerful nano-batteries will be part of the electronic device world within the next four years, estimates Nathan.
