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

Green Car Congress

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. —Jeremiah Johnson.

batteries using the same process of ion insertion and removal as in Li-ion batteries—have been discussed in the literature for some time. For cathode materials, the reversible, stable capacity of bulk Na + intercalation is usually limited to levels far below what can be obtained in Li-ion electrode materials. Earlier post.)
