In lithium batteries the anode requires a rigid electrolyte to block dendrite growth, but it is difficult for a rigid electrolyte to maintain sufficient contact with the solid cathode, which creates a highly resistive cathode/electrolyte interface. To address this problem, the researchers in China designed an asymmetrical solid electrolyte, in which the side facing the anode is a rigid ceramic material that presses against the lithium anode to discourage dendrite growth, the side facing the cathode is made of a soft polymer, which allows for a strong interfacial connection with the cathode. In tests, the new electrolyte showed no morphological changes even after 3200 hours of cycling, indicating that dendrite growth was effectively eliminated… read more. TECHNICAL ARTICLEÂ
