SolidEnergy Systems, or SES, has developed an “anode-free” lithium metal battery that improves overall life. According to MIT, material advances in SES’s batteries make them twice as energy dense while maintaining safety comparable to the lithium-ion batteries used in today’s smartphones, EVs, wearables, drones and other devices. With less weight and more space from a smaller battery pack, vehicles could become more lightweight or have more room for additional technology.

These batteries are touted to reduce production costs, be lighter, be scalable, charge faster and be more energy dense. We will see what comes of this, but it looks promising.
