Introduce common battery types

Common battery types Lithium polymer batteries from Anhui lithium-ion battery manufacturers are small in size and large in capacity. The disadvantage is that the life is shorter than 18650 because of the use of different designs and materials, some internal liquids, and some dry or colloidal. It has higher current discharge performance than the 18650 cylindrical battery, so the large-capacity electrical equipment I want is small in size, and lithium polymer batteries are often used. The most typical performance is the performance of mobile phones, tablets and other devices. Lithium-ion battery manufacturers rechargeable batteries are rechargeable batteries with limited charging time. There are usually 5, 7, and 1 on the market. The advantages of rechargeable batteries are economy, environmental protection, and sufficient power, which are suitable for high-power, long-term electrical appliances (such as walkmans, electric toys, etc.). The voltage of rechargeable batteries is lower than that of disposable batteries of the same type. AA batteries (no. 5 charge) are 1.2 volts, while 9V rechargeable batteries are actually 8.4 volts. Now the average charging time is about 1000 times. As of February 2012, there are only five types in the world: nickel-cadmium, nickel-metal hydride, lithium ion, lead storage and lithium iron. The active material on the positive plate of the lead-acid battery is lead dioxide, the active material on the plate is pure spongy lead, the electrolyte is a certain concentration of sulfuric acid solution, and the electromotive force between the plates is about 2V. The active material on the positive plate of the nickel-cadmium battery is nickel oxide powder, and the active material on the negative plate is cadmium oxide powder. The active material is wrapped in a perforated steel strip, and after pressure forming, it becomes the positive and negative plates of the battery. The electrolyte is usually a potassium hydroxide solution. The open circuit voltage of the battery is 1.2v. The positive electrode material of the metal nickel-hydrogen battery is nickel oxide powder, the negative electrode material is hydrogen-absorbing alloy, and the electrolyte is potassium hydroxide solution. Lithium-ion batteries use LiCoO2 composite metal oxides to form anodes on aluminum plates, and lithium-carbon compounds form cathodes on copper plates. There is a submicron microporous polyolefin membrane separator between the plates. The electrolyte is an organic solvent. Lithium polymer battery is an improved version of lithium ion battery. There is no battery fluid. Instead, a polymer electrolyte is used, which is more stable than ion batteries. The open circuit voltage is 3.6v. The battery capacity indicates how much power the battery can store. The numbers we see on the battery packaging generally refer to the battery capacity label. Expressed in units of amperes or milliamperes. It is a composite unit consisting of a current unit multiplied by a time unit, which represents the ability of the battery to continuously discharge under a constant current. A fully charged battery can be discharged for 10 hours at a current of 200mA. Multiply the current by the time to get a capacity of 2000 mA. H.400mA discharge, the use time is 5 hours. Energy density of lithium-ion battery manufacturers: the amount of electricity contained in a unit volume or unit weight. Regarding the same power requirements, high-energy-density batteries are smaller and lighter. Disclaimer: Some pictures and content of the articles published on this site are from the Internet.
