INTEGRATED FIBROUS SEPARATOR

An electrode including an integrated fibrous separator may include an active material layer layered onto a current collector substrate, and an integrated separator layer comprising a mixture of ceramic particles and fibers layered onto the active material layer. The fibers may be oriented substantially horizontally, and may be configured to increase a lateral strength of the electrode. In some examples, the electrode includes two or more active material layers disposed between the integrated separator layer and the current collector substrate. In some examples, the electrode includes an interlocking region disposed between the active material layer and the integrated separator layer.
