Lithium–silicon battery : ウィキペディア英語版 | Lithium–silicon battery
Lithium–silicon batteries are a lithium-ion battery technology under development, utilizing a silicon anode, that could theoretically offer much higher specific capacities than currently commercially available lithium-ion batteries. The first laboratory experiments with lithium-silicon batteries took place in the late 1990s. The large volume change of silicon when lithium is inserted is the main obstacle in commercialization of the technology. Mass production of batches of batteries using a silicon-graphite composite electrode has started in 2014, but these batteries are meant as test samples. ==Specific capacity==
A silicon anode has a theoretical specific capacity of 4200 mAh/g, more than ten times that of currently used anodes such as graphite (372 mAh/g).〔 This can be explained by the fact that silicon can bind with up to 4.4 lithium atoms in its fully lithiated state , compared to the one lithium atom per 6 carbon atoms for the fully lithiated state of graphite, .
