An electrolyte design strategy for making divalent metal batteries

Phys.org  October 8, 2021 Rechargeable magnesium and calcium metal batteries (RMBs and RCBs) are promising alternatives to lithium-ion batteries because of the high crustal abundance and capacity of magnesium and calcium. But they are plagued by sluggish kinetics and parasitic reactions. A team of researchers in the US (USA – University of Maryland, US Army, China) found a family of methoxyethyl-amine chelants that greatly promote interfacial charge transfer kinetics and suppress side reactions on both the cathode and metal anode through solvation sheath reorganization, thus enabling stable and highly reversible cycling of the RMB and RCB full cells with energy […]
