Latest Patents

Wang's latest patents include innovative technologies such as lithium-containing coatings for cathode materials. This invention features a positive electrode that includes a plurality of electroactive particles defining an electroactive layer. A first lithium-containing coating is applied to the electroactive layer, covering between about 30% and about 50% of its total exposed surface area. Additionally, a second lithium-containing coating encompasses at least one electroactive particle, covering between about 95% and about 100% of that particle. Both coatings have a thickness ranging from about 0.2 nm to about 5 nm. Furthermore, the positive electrode incorporates an electrolyte additive that facilitates the formation of passivation layers on the coatings.

Another notable patent is a method for manufacturing an interfacial lithium fluoride layer for an electrochemical cell that cycles lithium ions. This method involves positioning a substrate in a reaction chamber and introducing a lithium fluoride precursor that reacts with functional groups on the substrate. An oxidant is then introduced to form a single molecular layer of lithium fluoride at controlled temperatures.
