Weird Reality

Researchers from Tokyo Metropolitan University have developed a new quasi-solid-state cathode for solid-state lithium metal batteries, with significantly reduced interfacial resistance between the cathode and a solid electrolyte. By adding an ionic liquid, their modified cathode could maintain excellent contact with the electrolyte. Their prototype battery also showed good retention of capacity. Though finding the best ionic liquid remains challenging, the idea promises new directions in solid lithium...
