Army boosts Soldier battery power for greater lethality, mobility

The Army cannot rely on the commercial sector alone to meet its power demands because of Soldiers' requirements, such as the need to operate at extreme temperatures and withstand the rigors of combat conditions. For this reason, the electrochemical composition in battery components required for the military and consumer sector is different. 

"An increase in silicon content can greatly help achieve the high energy needs of the Soldier; however, a great deal of research is required to ensure a suitable product. These changes often require entirely new materials development, manufacturing processes and raw materials supply chains," Ruth said.
