Abstract

Abstract: Invited for this month's cover picture is the group of Prof. Kazuhide Ueno from Yokohama National University (Japan). The cover picture illustrates that less‐water‐soluble Ca‐based solid electrolyte interphase formed in a Li–Ca binary salt hydrate electrolyte effectively mitigates electrochemical reduction of water, leading to improvement in the cycle performance of a Li4 Ti5 O12 electrode.

Abstract : "Significant improvement in the cycle performance of a Li4 Ti5 O12 electrode was achieved using a Li–Ca binary salt hydrate (LCH) electrolyte in combination with an optimized electrochemical pretreatment process. The LCH electrolyte provided less‐water‐soluble Ca‐based SEI components, and careful pretreatment process enabled the formation of a thicker SEI layer on the Li4 Ti5 O12 electrode, leading to 95.5 % capacity retention over 50 cycles…" Learn more about the story behind the research featured on the front cover in this issue's Cover Profile.
