Scientists at Stanford and SLAC redesigned current conductors — thin metal foils that distribute current to and from electrodes — to make lithium-ion batteries lighter, safer, and more efficient.

Flashlight Battery Li-ion 18650 3.7V 3000mAh 11.1Wh has high energy density and high average output voltage.Small self-discharge, good battery, less than 2% per month (recoverable).

Lithium-ion battery refers to a general term for batteries with lithium-ion intercalation compounds as cathode materials. The charging and discharging process of lithium ion batteries is the process of intercalation and deintercalation of lithium ions.

The creation of the next generation of batteries depends on finding materials that provide greater storage capacity. One variety, known as lithium-air (Li-air) batteries, are particularly appealing to researchers because they have a significantly higher theoretical capacity than conventional lithium......

(Phys.org)—When Ovadia Lev, Professor of Environmental Chemistry and Health at The Hebrew University of Jerusalem, and his research team developed a new coating technology a few years ago, they thought it was an interesting outcome of their research in hydrogen peroxide solutions.

Scientists at the Tokyo Institute of Technology (Tokyo Tech) and the University of Tokyo (UTokyo) have developed a new three-valued memory device inspired by solid lithium-ion batteries.
