Constriction-susceptible makes fast cycling of lithium metal in solid-state batteries: Silicon as an example

摘要: Moreover, the work also inspires and provides ideas for the application of silicon in the liquid electrolyte battery (LEB) system. It is well known that as a typical alloying type anode, silicon has long been recognized as one of the most promising anode materials for lithium-ion batteries to replace graphite due to its extremely high specific capacity. However, owing to the huge volume expansion of Si during Li alloying and dealloying; the Si anode always experiences inevitable pulverization, making it very difficult to achieve rapid and stable cycling in current LEB. Therefore, it is highly expected that a function coating later with the similar concept of constriction-susceptible, could be applied in the LEB system to improve its performance.
