Related knowledge of backup battery

When the spare battery is first purchased, charge it once before using it, and then do not fully charge the lithium battery during the following use, let alone run out of power. When conditions permit, try to keep the battery's capacity close to half full, and the range of charging and discharging is as small as possible. Generally, the charging time of lithium batteries is 2-5 hours. After charging, you should be able to unplug the socket in time. Do not use the lithium battery for a long time with external power supply. Full charge for a long time is equivalent to the death of a lithium battery. Don't wait for your power bank to crash without knowing the reason. The mobile charging power supply itself has two aspects, one is plugged into the USB port of the computer, the other is plugged into the home power, plugged into the home power supply, because the length of the mobile power cord is limited, so please don't plug it into the wall socket , Hanging charges will cause damage to the mobile power supply. It is recommended that the mobile power plane be plugged into the multi-function clamp circuit socket to charge. The power bank is usually a standard USB interface. When charging mobile power, choose a reliable charger. The USB charger is of poor quality and has no overcurrent protection. *The power bank may be damaged during charging. The quality of the backup battery depends on the battery and the protection board. The battery is the basis of the life of mobile power. The life span of ordinary lithium polymer batteries is higher than that of 18650 cylindrical lithium batteries. The conversion rate of a good protection board can reach more than 90%, generally 80~85%, and the poor is only about 70%. If the conversion rate is less than 80%, it means the loss of the mobile power line, and the thermal battery itself is also very large. The conductive paint can effectively improve the adhesion of the electrode, reduce the use of binders, and improve the electrical performance of the battery. The products of large foreign companies will not be introduced. Products with independent intellectual property rights will be developed and processed by Dongguan Yunfan Electronic Technology Co., Ltd. to introduce domestic products and promote them in the market. The results show that in the case of the same multiplier, the contact resistance is reduced by 40%, the amount of adhesive is reduced by 50%, the battery voltage platform is increased by 20%, and the adhesion between the material and the collection fluid is increased by 30%. After a long period, there will be no stratification. Conductive coating is also called paint. The lithium battery industry usually refers to the coating on the positive electrode current collector, a conductive coating on the surface of aluminum foil, and the conductive coating aluminum foil is called pre-coated aluminum foil. Aluminum foil or coating was first used in experimental batteries. Dating back to the 1970s, with the development of the new energy industry, especially the development and popularization of lithium iron phosphate batteries, it has become the most popular new technology or new material. The carbon anode materials of large-capacity lithium batteries are basically carbon materials, such as artificial graphite, natural graphite, mesophase carbon microspheres, petroleum coke, carbon fiber, and pyrolytic resin carbon. Tin-based anode materials can be divided into tin-based oxides and tin-based composite oxides. Oxide refers to the oxide of tin, a metal of various valences, and there is no commercial product. Nitride, there is no commercial product. Alloys, including tin-based alloys, silicon-based alloys, germanium-based alloys, aluminum-based alloys, antimony-based alloys, magnesium-based alloys and other alloys, carbon nanotubes, and nano-alloy materials.
