"faster charging and better performance and comparatively high battery capacity at low temperatures all the way down to -80 degrees C... fluoroacetonitrile small molecule organic solvent electrolyte... the molecules tend to surround the lithium ions, forming a shell. As the shells touch, they form a sort of tunnel, allowing the ions to move more quickly through the electrolyte... ionic conductivity 40.3 millisiemens/ cm under ambient conditions, 4X that of standard batteries... sodium, potassium energy-storage"
