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.

New class of high-capacity cation-disordered oxides for Li-ion battery cathodes; up to 250 mAh/g

Green Car Congress

Gerbrand Ceder (now at UC Berkeley/Lawrence Berkeley Lab as of 1 July, formerly at MIT) have developed a new class of high capacity cation-disordered oxides—lithium-excess nickel titanium molybdenum oxides (Li-Ni-Ti-Mo, or LNTMO)—for Li-ion cathode materials which deliver capacities up to 250 mAh/g.

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.
