Do you really know the commonly used battery types?
"Common battery types"
As small as a watch, a remote control, as large as electric cars, aerospace. The application of batteries is really ubiquitous, all the time...
Since Volt invented the first battery, the battery has been continuously updated and iterated. Today's batteries have richer meanings and battery types. How much do you know about common battery types? Next, let's take a look~
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), and a dry battery is a disposable battery. Common dry batteries are zinc-manganese batteries (or carbon-zinc batteries).
In our life, dry batteries are widely used. It is not only suitable for flashlights, semiconductor radios, cameras, electronic clocks, wireless mice, children's toys, etc., but also in various fields of the national economy such as national defense, scientific research, telecommunications, navigation, aviation, medicine, etc. It is easy to use and very easy to use.
Lithium batteries are divided into lithium ion batteries, lithium metal batteries, etc.
Lithium-ion batteries generally use nickel-cobalt lithium manganate, lithium cobaltate, lithium manganate, lithium iron phosphate, etc. as the positive electrode material, graphite as the negative electrode material, and use a non-aqueous electrolyte battery. Lithium-ion batteries do not contain lithium in the metallic state and are rechargeable.
Lithium metal batteries generally use manganese dioxide as the positive electrode material, metal lithium or its alloy metal as the negative electrode material, and use a non-aqueous electrolyte solution.
Lithium metal batteries have higher energy.
The lithium-ion battery can be recharged and used repeatedly, and the cycle life of the lithium iron phosphate battery is more than 2000 times.
High rated voltage and high power tolerance.
Lithium metal batteries have low self-discharge rates and are lightweight.
High and low temperature adaptability.
Green. Regardless of production, use and scrapping, it does not contain or produce any toxic and harmful heavy metal elements and substances such as lead, mercury and cadmium.
A 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 or lead-acid battery.
Its working principle: when charging, it uses external electric energy to regenerate the internal active material, stores the electric energy as chemical energy, and converts the chemical energy into electric energy again when it needs to be discharged.
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 with certain illumination conditions, it can instantly output voltage and generate current in the presence of 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 before it can be supplied to household electricity or industrial electricity.
Regarding battery types, there are many subdivisions
