Kokam Co. Ltd., which claims to be the first company to have commercialized lithium polymer battery technology, has introduced high-energy battery solutions suited for unmanned systems, including drones.
With an energy density of 265 watt hours per kilogram (Wh/kg), the solutions enable military, commercial and industrial unmanned systems manufacturers to pack more energy into unmanned aerial vehicles (UAVs), as well as unmanned ground, surface and underwater vehicles, without increasing the weight or size of the systems’ batteries, explains Kokam. In turn, manufacturers can increase the operating time of their systems or add on other payloads.
In contrast, according to the Korea-based company, battery solutions for unmanned systems typically have energy densities of 150-200 Wh/kg. Kokam’s batteries are based on the company’s ultra-high energy nickel manganese cobalt technology.
Kokam’s new cells are available in capacities ranging from 10 ampere hours (Ah) to 240 Ah and can be purchased as individual cells or complete systems or in packs. The company says the solutions also come in a variety of sizes and weights and can be customized upon request.
