Moreover, the work also inspires and provides ideas for the application of silicon in the 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 anticipated that a function coating layer with similar concept of susceptible constriction could be applied in the LEB system to improve its performance.
