When soldiers depart on long patrols, the gear they carry weighs up to 100lbs. Deployable communication devices such as radios, GPS and night-vision goggles require the use of batteries in order to function. Batteries, along with water, contribute to 60-90 percent of the weight a soldier carries.  Because of this, the Department of Defense (DoD) has a particular interest in lightweight, long lasting batteries. Developing lightweight battery technology can result in lessening the burden of soldiers by lightening the load or allowing them to carry additional items.
