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