In ground equipment, lithium-ion batteries are mainly used in military unmanned ground vehicles, robots, hybrid electric vehicles and so on. For the ground combat vehicle driven by oil-electric hybrid, the use of lithium-ion battery as the power source can not only reduce fuel consumption and logistics burden, but also improve the maneuverability and survivability of tactical vehicles. At present, many armies have stepped up the research and development of lithium-ion battery modules for hybrid electric vehicles, unmanned ground vehicles and ground robots. However, for large-scale 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.
There are deficiencies in the application of large-scale equipment
