Hot Article: Improving the electrode-electrolyte interfaces in all-solid-state rechargeable lithium batteries using liquid state electrolytes

Fabrication of electrode–electrolyte interfaces in all-solid-state rechargeable lithium batteries by using a supercooled liquid state of the glassy electrolytesIn order to reduce emissions of CO2, high-performance lithium ion batteries have received a lot of attention as new large-scale power storage systems for eco-cars. In order to improve the electrochemical performance of the all-solid-state cells, an electrochemically favourable electrode–electrolyte interface has to be fabricated. In the case of using solid electrolytes, it is considered that the contact area between active materials and solid electrolytes is smaller than the contact area between active materials and liquid electrolytes because solid electrolytes are not wettable and infiltrative like liquids.

To find a solution to this problem, Masahiro Tatsumisago and colleagues in Japan investigated the softening behavior of a 80Li2S·20P2S5 (mol%) glass electrolyte, and a favorable electrode–electrolyte interface was fabricated by sticking the supercooled liquid state of the 80Li2S·20P2S5 electrolyte on active material particles.
