Cuberg lithium metal battery powered quadcopter achieves 70% increase in flight time

Cuberg demonstrated the world's first vertical take-off and landing (VTOL) drone powered by a safe lithium metal battery. In a face-off test, a quadrocopter powered by Cuberg's lithium metal battery technology showed a 70% longer flight time than the same drone powered by lithium-ion technology.

"Our high-performance electrolyte chemistry has been ready for real-world testing for several months, but until we built our first commercial-quality cells, we could only estimate its flight performance based on lab data. We’re very pleased to report our first flight tests outside the lab outperformed our highest expectations,” says Cuberg co-founder and CEO Richard Wang. “We ran the flight comparison test several times and observed consistently excellent results.”
