E-magy's high energy density lithium ion battery cell provides a next-generation electric power solution for multirotor and hybrid VTOL drone platforms, utilising a unique silicon anode technology to provide higher capacity and faster charging times in a low-cost and compact form factor.
Thanks to a pioneering manufacturing process that utilises a nanoporous structure with high mechanical stability, the cell does not suffer from the swelling and breaking issues common to other silicon technologies. The cells are also highly environmentally friendly and cost-effective, using abundantly available metallurgical-grade silicon and a highly efficient casting process with a low carbon footprint.
The lightweight battery solution has consistently achieved over 30 minutes of drone flight time for up to 186 flight cycles. The first iteration of the technology is already in production, and an improved cell design is expected to be ready for sampling in Q3 2026.
