The Problem We Solve

EVs carry battery weight in two ways

Conventional EVs bear two separate mass burdens: energy storage and the load-bearing chassis. A 600kg battery pack supplies energy but adds nothing to the vehicle's structural integrity.

Sasung Power cells are designed to carry charge and compressive load together. Their carbon-fiber reinforced polymer laminate is the cell housing, floor panel, side sill, and structural member that preserves rigidity in a side-impact event.

Applications

Structural batteries across three sectors

Removing the battery pack creates compounding benefits across three sectors.

Electric Vehicles

Floor panels, side sills, and door structures serve as the battery system. Cut mass 12-18% versus pack-based architectures at equivalent energy capacity.

EV integration guide

Industrial Robotics

Manipulator arm segments and mobile platform chassis provide their own energy storage. Extend runtime without a payload penalty in collaborative robot applications.

Robotics architecture

Urban Air Mobility

eVTOL fuselage panels and rotor booms carry aerodynamic loads and energy storage, creating range margins beyond conventional pack placement.

UAM applications

Sasung's structural cell measured 8.1 GPa elastic modulus and showed full electrochemical cycle retention after 200 impact simulation events. We did not expect that combination from a team at this stage.
