Abstract
A prelithiated anode may include a current collector may include a metal oxide layer. Prelithiated anodes may in addition include a lithiated storage layer overlaying the metal oxide layer. The lithiated storage layer may be formed by incorporating lithium into a continuous porous lithium storage layer may include at least 80 atomic % silicon. The lithiated storage layer may include less than 1% by weight of carbon-based binders. The lithiated storage layer may further include lithium in a range of 1% to 90% of a theoretical lithium storage capacity of the continuous porous lithium storage layer. Batteries may include the prelithiated anode.
