Redefining Li-ion Manufacturing


The Energy vs. Power Tradeoff

All batteries face the inherent tradeoff between energy and power, the difference between storing enough energy and delivering it fast enough. Until now, industries have faced this challenge by designing around these constraints. However, today's Li-ion technology is still far from delivering the energy and power required for several market segments, and a drastic push in the entire performance envelope is desperately needed.
Energy vs. power tradeoff


We have developed a breakthrough manufacturing process for making key components in the Li-ion battery. This allows us to push the energy and power performance envelope like never before. With our scaled-up, low-cost manufacturing process, we are taking a fundamentally different approach to engineer batteries with unparalleled performance.
