ProLogium and Elysian Aircraft Collaborate on Next-Gen Ceramic Batteries for Electric Aviation

ProLogium and Elysian Aircraft have entered an agreement to evaluate the use of lithium ceramic batteries for large-scale electric aviation, targeting flights of up to 621 miles on a single charge. The partnership aims for an energy density of 320 to 420 watt-hours per kilogram, addressing the high demands of aviation for energy efficiency, safety, and weight.

Ceramic batteries offer advantages over traditional lithium-ion designs, particularly in reducing weight and enhancing thermal stability, potentially minimizing cooling needs and fire risks. If successful, this technology could enable cleaner regional air travel, reducing noise and air pollution near airports. However, the challenge remains in achieving energy densities comparable to conventional jet fuel, which delivers about 12,000 watt-hours per kilogram.
