Inferior lithium iron phosphate battery safety risk analysis

Source: 2020 - 04 - 14 20:08 hits: lithium iron phosphate battery in communication industry application and advantage of communication base station is vital for the whole city of wireless communication, everywhere, it makes the network base stations, to stop working, there is no signal, such as mobile phone no network, the remote will be cut off, such as the failure of the Internet age will no doubt bring inconvenience to the life, so it is very important to the operation stability of the base station. Due to the high reliability of communication, perfect communication power supply solutions require switching power supply system with high reliability, high security of the battery. But lead-acid battery life is shorter, frequent maintenance, extremely in the greenhouse environment is far less than that of lithium iron phosphate battery performance is stable, although the price is expensive, but for the importance of the communication industry, the charge is totally worth it, we look forward to the future of lithium iron phosphate batteries will become the main equipment, auxiliary equipment, and many other types of main power supply configuration. Lithium iron phosphate battery has the following application: (in the communications industry a) Outdoor base station; ( b) No air conditioning in the base station, such as the village. ( c) Limited space of indoor large radio; ( d) Indoor covered/distribution of dc power station; ( e) When there is no power lines or three or four set up photovoltaic power line stations; ( f) For the use of dc power supply plan of the wireless LAN site, etc. Connected to the ac power supply system, UPS UPS ac power system is mainly used for ac main circuit of power supply and distribution system. UPS ac power system applied in the communications industry scenario is as follows: ( a) Indoor ac power cover/distribution station; ( b) Communication microcells station; ( c) Built-in data of UPS power supply room; ( d) For ac power plans to use the wireless LAN site, etc. 240 v / 336 v high voltage dc power system ( HVDC) Inferior battery safety risk a lot of industry business in order to save the cost of production, production of inferior lithium-ion batteries, or a lot of businesses, products from manufacturers to buy B cells, also known as' shanzhai cell, while consumers covet is cheap to buy counterfeit batteries. Battery safety problem is not limited to the phone. At present, all kinds of battery has become the basic equipment of modern life, mobile phones, laptops, all kinds of portable devices cannot leave the battery, if use improper use or bad batteries, these batteries have the possibility of explosion. In the fierce market competition, most battery manufacturers in pursuit of high profits, using low cost or even inferior material, this is the main reason for the cell phone battery explosion. Because of the lithium ion battery energy density is high, in the condition of charge and discharge, battery temperature, excess energy, produce gas, electrolyte decomposition battery pressure rise sharply, the risk of spontaneous combustion or explosion. More and more manufacturers to pursue output rather than quality. In the fierce market competition and driven by the interests, most companies use cost is low, the safety risk is relatively high liquid lithium battery. Ignore the interests of consumers, even some small retailers use inferior battery and protective plate, lead to battery explosion accident!
