Russian laptop batteries last 10 hours
Russian scientists have developed a laptop battery that can work up to 10 hours without recharging, according to RIA Novosti news agency.
The new battery is based on fuel cells technology. That means it is fed with substance for electrochemical reaction - usually methanol or hydrogen - from outside.
Such power units can work as long as they are fed and do not need recharging.
“This is a sci-tech and market revolution based on Russian engineering designs,” said Prof. Lev Trusov, the project developer.
Trusov believes a modern laptop battery should weigh no more than 100-150 grams, and the Russian invention of a thin multi-layer nanostructure solves the problem of high energy density per volume unit.
The developers aim to make the new batteries to a high safety standard for users.
