Abstract: This disclosure relates to systems and methods for charging a battery. An example embodiment includes receiving information about an initial state of charge of a battery. If an initial state of charge is less than a predetermined threshold and if a charger is electrically coupled to the battery, a charger may be configured to charge the battery according to a preferred charge rate higher than a default charge rate. A charging duration is determined based on a type of the battery, the initial state of charge, a target state of charge, and the charge rate. A controller may determine a partial charge condition based on at least one of: providing electrical current to the battery at the charge rate for the charging duration or receiving information indicative of a state of charge of the battery reaching the target state of charge.

Abstract: This disclosure relates to a battery and a method for its manufacture. An example method includes forming a substrate having a first surface, the first surface having a plurality of pores. The pores may be configured to house lithium metal. The method includes incorporating lithium metal into at least a portion of the plurality of pores. The lithium metal may be incorporated into the pores via a pre-lithiation process, which may include electroplating of lithium metal into the porous substrate. The method also includes forming an electrolyte disposed between the first surface of the substrate and a cathode. The electrolyte is configured to reversibly transport lithium ions via diffusion between the substrate and the cathode. The method also includes forming the cathode. Some embodiments may provide the substrate to jointly serve as an anode and electrically-conductive current collector.
