Abstract
Provided are electrodes for use in electrochemical cells and active material components used to form these electrodes. Also provided are methods of forming these active material components as well as methods of forming these electrodes. An electrode comprises a current collector and an active layer, comprising active material structures and an inorganic conductive layer. The inorganic conductive layer coats and binds together these active material structures. Furthermore, the inorganic conductive layer also provides adhesion of the active layer to the current collector. The inorganic conductive layer has an electronic conductivity of at least 10S/m and provides an electronic path among the active material structures and, in some examples, between the active material structures and the current collector. In some embodiments, the same inorganic conductive layer shared by multiple active material structures.
