In ground equipment, lithium ion batteries are mainly used in military unmanned ground vehicles, robots, hybrid electric fighting vehicles, etc. For hybrid ground fighting vehicles, the use of lithium-ion batteries as power sources can not only reduce fuel consumption, reduce logistics burden, but also improve the mobility and survivability of tactical vehicles. At present, many militaries have increased the research and development of lithium-ion battery modules for hybrid electric vehicles, unmanned ground vehicles and ground robots. However, the weak power of lithium-ion battery is the main factor restricting its further application for large ground equipment. 
it is necessary to continue to develop high specific power and low cost lithium ion batteries in the future to meet the mission requirements of ground equipment.
It has wide applicability in military application
