SolidEnergy technology can potentially deliver energy densities of up to 800 Wh/kg—twice the energy density of state-of-the-art batteries and four times the energy density compared to conventional lithium-ion batteries.
The SolidEnergy prototype battery combines a Li(NiMnCo)O2 (NMC) cathode; the novel electrolyte; and a solid-polymer-coated lithium metal anode. The electrolyte combines ionic liquid and liquid polymer to provide both the safety and wide temperature capability required for advanced batteries, while the solid-polymer-coated lithium anode significantly boosts energy density and cycle life.
