Technical analysis of new energy 14500 battery

From the current point of view, the development of 14500 battery in China has entered the fast lane, mainly due to the rectification of the lead-acid battery industry and the country's active promotion of new energy, which has led to the emergence of new 14500 battery. High-temperature 14500 battery: At present, the backup power supply widely used in communication base stations and IDC computer rooms is ordinary lead-acid valve-controlled sealed 14500 battery, with the best operating temperature of 20℃-25℃. They are very sensitive to high-temperature use environments, that is, long-term use in an environment above 25℃, and the battery life will be reduced by half for every 10℃ increase in temperature. Therefore, most base stations and IDC computer rooms need to be equipped with air conditioners, which consume a lot of energy. Increasing the working temperature of the battery can not only greatly improve the reliability and safety of the backup battery of the communication base station, but also greatly reduce the air conditioning energy consumption caused by battery cooling, and promote energy conservation and emission reduction in my country's communication industry. Lithium 14500 battery: In the field of backup power supply for communication, with the development of access networks and the miniaturization of communication cabinets, lithium-ion 14500 battery with higher weight and volume specific energy are gaining attention and attention from power workers in the communication field. Many foreign communication equipment manufacturers have launched a series of backup lithium-ion battery packs for communication, and large operators have begun to successfully apply them. With the continuous development of technology and the continuous reduction of costs, there will definitely be new technologies to replace lead-acid 14500 battery in the future. Therefore, in the field of communication power supply in the future, operators will accept and use lithium iron phosphate 14500 battery on a large scale. Lithium-ion 14500 battery with higher specific energy are developing rapidly. Lithium-ion 14500 battery with lithium iron phosphate as the positive electrode material have shown good floating charge performance, safety, reliability and excellent cycle performance, and will surely become an important technical type of 14500 battery for future communication power supply. However, the cost of lithium-ion 14500 battery is equivalent to 4-5 times that of lead-acid 14500 battery, which to a certain extent restricts the widespread use of this product. Its application direction will be limited to small-capacity communication equipment power supplies such as broadband and access networks or as mobile communication power supplies for a period of time. Fuel cells: Looking at the development history of fuel cells for more than 170 years, it can be seen that fuel cells are gradually extending from special aerospace and independent power stations to electric vehicle power supplies, portable digital product power supplies, backup power supplies and other fields, because they have outstanding advantages such as high energy conversion efficiency (up to 50% or more), good reliability, no pollutant discharge, low noise (<55dBA), and continuous operation without charging. In addition, fuel cells can also form a flexible hybrid power supply solution with solar energy, city electricity, 14500 battery and other power sources. At this year's communications exhibition, exhibitors also displayed 14500 battery using hydrogen energy. The emergence of new 14500 battery has its inevitable reasons. The above three new 14500 battery have attracted widespread attention since their birth. The new 14500 battery have incomparable performance advantages. However, new 14500 battery are bound to be new things, and many disadvantages have not yet been fully revealed. For users, they should be cautious in the selection process.
