Provided herein are systems, apparatuses, and methods of providing electrical energy for electric vehicles. A battery pack can be disposed in the electric vehicle to power the electric vehicle. A battery cell can be arranged in the battery pack. The battery cell can have a housing. The housing can define a cavity within the housing. The battery cell can have an electrolyte arranged within the cavity. The battery cell can have a cathode disposed within the cavity along one side of the electrolyte. The battery cell can have an anode disposed within the cavity along another side of the electrolyte. The anode can have a silicon-carbon structure. The silicon-carbon structure can be doped with lithium material prior to an initial charge cycle of the battery cell. The anode can have a negative electrode capacity 20-50% greater than a positive electrode capacity of the cathode.
本发明提出了为电动交通工具提供电能的系统、装置和方法。电池组可以放置在电动交通工具内为电动交通工具提供动力。电池单元可以设置在电池组中。电池单元可以具有壳体。壳体可以在其内限定出空腔。电池单元可以具有设置在空腔内的电解质。电池单元可以具有沿电解质一侧放置在空腔内的阴极。电池单元可以具有沿电解质另一侧放置在空腔内的阳极。阳极可以具有硅碳结构。在电池单元的初始充电循环前,硅碳结构可以掺杂锂材料。阳极的负电极容量比阴极的正电极容量大20‑50%。
