We call devices that can directly convert chemical energy, internal energy, light energy, atomic energy and other forms of energy into electrical energy as batteries. Batteries are widely used in life, production, scientific research and other fields. Today I will analyze it from the big classification. Hope it helps you.
A dry battery is a chemical battery that uses a paste electrolyte to generate direct current (a wet battery is a chemical battery that uses a liquid electrolyte). It can be used in many electrical appliances with the batteries made in the laboratory.
Dry batteries are not only suitable for flashlights, semiconductor radios, tape recorders, cameras, electronic clocks, toys, etc., but also for national defense, scientific research, telecommunications, navigation, aviation, medicine and other fields of the national economy, very easy to use.
Lithium battery is a kind of battery that uses lithium metal or lithium alloy as negative electrode material and uses non-aqueous electrolyte solution.
Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium-ion batteries do not contain lithium in the metallic state and are rechargeable.
- energy is relatively high.
- Long service life, the service life can reach more than 6 years.
- High rated voltage (single operating voltage is 3.7V or 3.2V).
- With high power tolerance.
- The self-discharge rate is very low.
- High and low temperature adaptability.
- Green and environmentally friendly, regardless of production, use and scrap, it does not contain or produce any toxic and harmful heavy metal elements and substances such as lead, mercury, and cadmium.
- Production basically does not consume water, which is very beneficial to my country, which is short of water.
- Lithium primary batteries have poor safety and there is a danger of explosion.
- Lithium-ion batteries of lithium cobalt oxide cannot be discharged at large currents, are expensive and have poor safety.
- Li-ion batteries need to protect the circuit to prevent the battery from being overcharged and overdischarged .
- The production requirements are high and the cost is high.
- The use conditions are limited, and the high and low temperature use is dangerous.
A storage battery is a device that directly converts chemical energy into electrical energy. It is a rechargeable battery designed to be recharged through a reversible chemical reaction, also known as a secondary battery.
Its working principle: use external electric energy to regenerate the internal active material during charging, store the electric energy as chemical energy, and convert the chemical energy into electric energy output again when it needs to be discharged, such as mobile phone batteries commonly used in life.
The battery is a chemical “power source” widely used in the world. It has the advantages of stable voltage, safety and reliability, low price, wide application range, abundant raw materials and high recycling rate. It is the largest and most widely used battery in the world. A wide range of batteries.
A solar cell, also known as “solar chip” or “photovoltaic cell”, is an optoelectronic semiconductor sheet that uses sunlight to generate electricity directly. As long as it is illuminated by light that meets certain illumination conditions, it can instantly output voltage and generate current when there is a loop. In physics, it is called solar photovoltaic, or photovoltaic for short.
Since the electricity generated by solar cells is direct current, if you need to provide power to household appliances or various electrical appliances, you need to install a direct/AC converter and replace it with alternating current, so that it can supply electricity for household or industrial use.
