In situ engineering of the electrode-electrolyte interface for stabilized overlithiated cathodes
Here, the first-ever demonstration of stabilized Si/lithium-manganese-rich full cells, capable of retaining >90% energy over early cycling and >90% capacity over more than 750 cycles at the 1C rate (100% depth-of-discharge), is made through the utilization of a modified ionic liquid electrolyte capable of forming a favorable cathode-electrolyte interface.

All-solid-state disordered LiTiS 2 pseudocapacitor
A lithium charge storage mechanism is discovered at the interface of nano-crystallites of LiTiS 2 in the solid state. The surface titanium atoms can be reduced reversibly at higher voltages. Electrochemically, this appears as a pseudocapacitive effect boosting capacity greater than theoretical at high rate with no liquid electrolyte.
