AAA is a type of battery with a specific shape, commonly known as an AA battery. This is the smallest type of standard cylindrical battery.
Dry battery is a disposable battery, usually refers to manganese-zinc battery (also called acid battery) or manganese-iron battery (also called alkaline battery), their voltage is 1, 5V, appearance They are all cylinders with different sizes and are divided into several common standard specifications: R20 (No. 1), R16 (No. 2), AA (No. 5) and AAA (No. 7).
Lithium batteries are currently the best type of battery and can release the greatest amount of electrical energy in the same volume. The voltage of a single battery is 3.6V and it is divided into two categories: rechargeable batteries and non-rechargeable batteries. As for the appearance, it is very complicated and basically does not have a standard shape. >The differences between the two are: comdifferent chemical positions, different voltages, different energy densities, different charge and discharge lifetimes, etc.
Chemical composition: Dry batteries generally use chemicals such as manganese and zinc as positive and negative electrodes, while lithium batteries use metallic lithium or lithium ions as positive and negative electrodes.
Voltage: The voltage of dry cell batteries is typically 1.5 volts, while that of lithium batteries is typically between 3.6 volts and 3.7 volts.
Energy density: Lithium batteries have a higher energy density than dry batteries and can store more electrical energy.
Charging and discharging life: Lithium batteries have better charging and discharging life and can be recycled many times, while dry batteries are more durable.are generally single-use and cannot be refilled.
