[0002] Most of the existing AA batteries are nickel-metal hydride rechargeable batteries, nickel-cadmium rechargeable batteries, alkaline zinc-manganese batteries (referred to as "alkaline batteries"), and ordinary acidic zinc-manganese batteries (referred to as "ordinary batteries"), and there are no products that convert sodium batteries to dry batteries.

[0003] Modern dry cell batteries primarily rely on internal chemical reactions to generate current. Moreover, most of these chemical reactions are irreversible, resulting in the batteries being non-rechargeable and having limited capacity. Furthermore, the chemical substances inside dry cell batteries continue to react slowly even when not in use, leading to a high self-discharge rate. Additionally, the electrode materials, electrolytes, and contact interfaces within dry cell batteries introduce resistance, limiting the ability to conduct large currents and thus limiting output power.
