SES

ses.ai

Every once in a while, a new battery technology comes along showing promise in one area, but is objectively worse in almost everything else compared to Li-ion. Maybe it’s low energy density, or short cycle life, or poor power density, or expensive, or just never built a real cell. SES, formerly known as SolidEnergy, used to pursue solid state Li-Metal technology but pivoted away from it, due to the low energy density, high temperature requirement, and fundamentally expensive and difficult-to-scale manufacturing process. Instead, SES developed a more practical and complete Hybrid Li-Metal system including safe and high efficiency electrolyte, anode protective coating, cell engineering and manufacturing capabilities, and AI-powered algorithm for health monitoring and fast charging.
