Abstract: The present disclosure relates to a battery incorporating a hybrid gel/solid electrolyte. In an example embodiment, a battery may include a copper anode current collector, a lithium metal anode, a lithium phosphorous oxynitride (LiPON) anode protector, an electrolyte, a lithium cobalt oxide (LiCoO2) cathode, and an aluminum cathode current collector. The electrolyte may include a gel electrolyte, a solid electrolyte, and a separator. The separator includes an insulating material layer disposed between a first gel electrolyte layer and a second gel electrolyte layer. In some embodiments, the insulating material may include polyethylene and the gel electrolyte layer may include a liquid and a polymer. Alternatively or additionally, the solid material may include a filler material, which may include silica and a polymer.

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 translation: 本公开涉及对电池充电的系统和方法。 示例实施例包括接收关于电池的初始充电状态的信息。 如果初始充电状态小于预定阈值，并且如果充电器电耦合到电池，则充电器可以被配置为根据高于默认充电速率的优选充电速率对电池充电。 基于电池的类型，初始充电状态，目标充电状态和充电速率来确定充电持续时间。 控制器可以基于以下中的至少一个来确定部分充电状况：以充电持续时间的充电速率向电池提供电流，或接收指示电池达到目标充电状态的充电状态的信息。
