Detailed explanation of the application of iron-lithium ion batteries in the aerospace and military fields

Application of Lithium-Ion Batteries in Aerospace As the performance of Lithium-Ion batteries has greatly improved, the scope of application has also expanded from the field of civil consumption to the field of aerospace. Lithium-ion batteries were first used in business jets in the field of civil aviation, but their use time was short and their application range was not wide. With the Boeing 787 using lithium-ion batteries in operation in 2011 as a sign, the application of lithium-ion batteries in the aviation field had the first climax, but subsequent accidents brought the application of iron-lithium-ion batteries to a halt. Boeing is a leader in the use of advanced large-capacity and high-power lithium-ion batteries. Its Boeing 787 installed lithium-ion batteries as the main battery and auxiliary power unit batteries in 2011, becoming the world's first aircraft to be used in key aircraft systems. Civil airliner with lithium-ion battery technology. Relevant experience in the use of large-capacity and high-power lithium-ion batteries in the civil aviation field shows that the energy density, number of recharges, cycle life, safety and cost of lithium-ion batteries are important indicators of the battery, of which energy density is particularly critical. At present, many companies try to use chemical methods to increase the energy density of batteries. In the future, lithium-ion batteries must develop in the direction of lithium metal batteries to meet the requirements of a variety of aircraft. With the maturity of iron-lithium-ion battery technology and the improvement of performance, high-performance and large-capacity lithium-ion batteries will further meet the power requirements of a new generation of multi-electric civil aircraft, reduce the weight of aircraft, and encourage civil aircraft manufacturers to gradually use them for Aircraft emergency lighting, cockpit voice recorder, flight data recorder, recorder independent power supply, backup or emergency power supply, main power supply and auxiliary power unit power supply and other airborne systems. Application of Lithium Iron Battery in the Military Field In military equipment, lithium iron phosphate batteries are mainly used as power starting power source, wireless communication radio power source, power source of micro unmanned reconnaissance aircraft, etc., in addition, such as laser sight, night vision Nowadays, lithium iron phosphate batteries are commonly used in power supplies for aircraft and pilot life-saving radio stations. A few days ago, South Korea claimed that its lithium-ion battery submarine was superior to the previous Japanese-made world’s first lithium-ion battery submarine, the Phoenix Dragon. According to previous Japanese media reports, the Phoenix Dragon may be exported to the Philippines for military applications. In addition to lithium-ion battery submarines, South Korea is also developing a seawater battery in recent years and is expected to use it for commercialization. It is reported that the Ru0026D team is working to improve the technology of seawater batteries in order to bring them to the market in the future. Related sources said that seawater batteries will also be used in militarized unmanned submarines and unmanned surface craft. Two American scientists have developed an iron-lithium ion battery that can be pulled at will to restore its shape and its performance is not affected. It can supply power for innovative electronic equipment, and truly realize the miniaturization and extended integration of electronic devices and power sources. . Some critics believe that this kind of battery can be effective in areas where ordinary batteries cannot work, and its military application prospects are very promising. The special function of lithium-ion battery in some military equipment cannot be replaced by other batteries. The primary lithium-ion battery has great potential in some electrical properties and needs to be developed; the research and development of the secondary lithium-ion battery with lithium metal as the negative electrode is not wrong. Therefore, we should continue to strengthen the research and development of lithium-ion batteries. Military applications require lithium-ion batteries with excellent performance, and the price is not a decisive factor.
