No pressure! Nuvvon 5Ah SiC NMC solid state

Author Dr. Simon Madgwick of Nuvvon Inc. Nuvvon recently showed their solid state 5Ah SiC NMC cell cycling continuously at 3C/5C for 1000 cycles full DOD to 90% SOC. Then incredible sub-zero temperature performance discharging down to -50°C with over 50% capacity and charging at -40°C. Here is the final post on these 5Ah Silicon cells – comparing … Read more

An Introduction to Solid Polymer Electrolytes

radar plot of solid polymer electrolyte properties

Among the two broad classes of solid electrolytes, inorganic ceramics currently offer the highest room-temperature conductivities (10⁻³–10⁻² S cm⁻¹) but demand high-temperature sintering, are mechanically brittle, and suffer from large interfacial impedance with composite electrode [1]. Solid polymer electrolytes (SPEs), such as polyethylene oxide (PEO)–LiTFSI, polycarbonates, and block-copolymer systems, trade some conductivity (10⁻⁵–10⁻³ S cm⁻¹ … Read more
