MIT electrolyte enables ultra-high voltage Ni-rich cathodes in Li-metal batteries

Green Car Congress

V in lithium-metal batteries (LMBs). The electrolyte not only suppresses side reactions, stress-corrosion cracking, transition-metal dissolution and impedance growth on the cathode side, but also enables highly reversible Li metal stripping and plating on the lithium-metal anode (LMA), leading to a compact morphology and low pulverization.

Researchers show that layered calcium transition metal oxides can be promising cathode materials for Ca-ion batteries

Green Car Congress

Out of several candidates that could replace Li in rechargeable batteries, calcium (Ca) stands out as a promising metal. Not only is Ca 10,000 times more abundant than Li, but it can also yield—in theory—similar battery performance.

ANL team develops new class of Li- and Na- rechargeable batteries based on selenium and selenium-sulfur; greater volumetric energy densities than sulfur-based batteries

Green Car Congress

Cycling performance of Li/SeS 2 ?C, Researchers at Argonne National Laboratory have developed selenium and selenium–sulfur (Se x S y )-based cathode materials for a new class of room-temperature lithium and sodium batteries. Unlike the widely studied Li/S system, both Se and Se x S y can be cycled to high voltages (up to 4.6
