In ground equipment, lithium ion batteries are mainly used in military unmanned ground vehicles, robots, hybrid electric combat vehicles, etc. For ground combat vehicles that use hybrid electric power, using lithium ion batteries as a power source can not only reduce fuel consumption, Reducing the logistics burden can also improve the motive power and survivability of tactical vehicles. At present, the multinational army has increased the research and development of lithium-ion battery modules for hybrid electric-driven chariots, unmanned ground vehicles, and ground robots. However, for large-scale For ground equipment, the weak power of lithium-ion batteries is the main factor restricting its further application. Therefore, it is necessary to continue to develop high specific power, low-cost lithium-ion batteries to meet the mission requirements of ground equipment. According to this text, lithium-ion batteries:. ['There are deficiencies in the application of large equipment.', 'Broad applicability in military applications.', 'vigorously developed as a new type of battery by various countries.', 'Is the development direction of future battlefield power sources.']
