3M’s Silicon Anodes Could Boost Gadget Battery Life by 40 Percent
Graphite is a uncouth choice for anodes in Li - Ion battery systems but does n’t put in much charge for its bulk . However , 3 M ’s newly - devised electrode could hike up battery life sentence and substitute the soft - carbon material for dear . 3 metre ’s fresh anodes are made of silicon - atomic number 3 metal that predict a 20 - percent increment in Department of Energy compactness when used with formal cathode ....
