What are the battery types? What types of batteries can be divided into?
Batteries have long become an indispensable part of our lives. In order to meet the needs of different products, many different types of batteries have been developed, but many people do not know what types of batteries are there. Let me tell you:
The first type of chemical battery: a device that converts chemical energy into electrical energy through a chemical reaction;
What kind of batteries are included in chemical batteries:
1. Primary batteries, which are commonly used disposable batteries (No. 5, No. 7, disposable button batteries and other disposable batteries);
2. Secondary batteries, which are commonly used rechargeable batteries (lead-acid batteries, nickel-hydrogen rechargeable batteries, lithium-ion batteries, etc.);
3. Fuel cells, such as the hydrogen fuel cell promoted by Japan;
The second type of physical battery: a device that converts electrical energy through physical reactions;
1. Physical batteries, such as solar power and solar cells, which are the main promotion of our country;
2. Thermal battery, also called molten salt battery, thermally activated reserve battery, mainly used for power supply of missiles, rockets and emergency electronic instruments;
3. Double-layer electrical capacitors, also known as super capacitors, have no material changes involved in the charging and discharging process;
The third type of biological battery: is a device that directly converts biomass energy into electrical energy;
Enzymolysis battery/microbial battery, as a representative of bio-battery, has not many applications.
