What is the difference between lithium batteries and dry cells?

1. Different materials

1. Lithium battery: It uses manganese dioxide as the positive electrode material, lithium metal battery metal as the negative electrode material, and uses non-aqueous electrolyte solution battery.

2. Dry Battery: This is a voltaic battery that uses some absorbent (like sawdust or gelatin) to turn the contents into a paste that will not spread.

2. Different principles

1. Lithium battery: It adopts a spiral winding structure and uses a very thin and highly permeable polyethylene film. is spaced between the positive and negative electrodes.

2. Dry battery: the carbon rod is used as the positive electrode and the zinc cylinder is used as the negative electrode, which converts chemical energy into electrical energy and supplies it to the external circuit. In the reactionschemically, because zinc is more active than manganese, zinc loses electrons and oxidizes, while manganese gains electrons and is reduced.

3. Different uses

1. Lithium batteries: widely used in mobile phones, laptops, power tools, electric vehicles, emergency power supplies for street lights, and navigation lights, small household appliances.

2. Dry batteries: suitable for flashlights, solid-state radios, tape recorders, cameras, electronic clocks, toys, etc., and also suitable for various fields of national economy such as national defense, scientific research, telecommunications, navigation, aviation, medicine, etc.

Usage Notes

First, keeping lithium-ion batteries properly charged and discharged can extend battery life. Hold thenLithium-ion battery life between 10% and 90% is beneficial to protect the battery. This means that when charging batteries of digital products such as mobile phones and laptops, it is not necessary to reach the maximum value.

If digital products equipped with lithium-ion batteries are exposed to sunlight or stored in hot cars, it is best to keep these products turned off because if the operating temperature exceeds 60 degrees Celsius, the lithium battery -ion ​​will accelerate aging.

Lithium battery charging temperature range: 0-45 degrees Celsius, lithium battery discharge temperature range 0-60 degrees Celsius.

Second, if the cell phone battery needs to be charged every day, the reason may be that the battery is defective or it is time to "retire".

For laptop owners, it isIt's best to remove the battery if it's plugged in for a long time (the high heat generated by the computer while in use is not good for the laptop battery).

Third, under normal circumstances, 50% power is most conducive to the preservation of lithium-ion batteries.
