TLDR:

  • A research team has enhanced the performance of all-solid-state batteries through bottom electrodeposition.
  • They developed an anode protection layer that promotes stable electrodeposition of lithium from the bottom.

A recent breakthrough in all-solid-state battery technology has been achieved by a research team focusing on enhancing the performance and durability of these batteries. The team implemented a novel approach called bottom electrodeposition to address issues related to the indiscriminate electrodeposition of lithium in all-solid-state batteries. This breakthrough is crucial in improving the safety and efficiency of secondary batteries used in various applications such as electric vehicles and energy storage systems. The research, published in Small, highlights the development of an anode protection layer made of a functional binder that facilitates stable lithium transfer, preventing random electrodeposition. This layer promotes a process known as ‘bottom electrodeposition,’ ensuring that lithium is uniformly deposited from the bottom of the anode surface. The team’s all-solid-state batteries demonstrated stable electrochemical performance over extended periods, even with ultra-thin lithium metal anodes. The findings pave the way for further advancements in battery technology and potential commercialization of lithium metal anodes.
