High capacity and high rate batteries

Abstract From the Canadian patent

Improved batteries described herein generally comprise an electrolyte having lithium ions and a cathode comprising submicron metal vanadium oxide particles. In some embodiments, the battery demonstrate an accessible current capacity of a least about 220 mAh/g when pulsed in groups of four constant energy pulses at a current density of 30 mA/cm2 to deliver 50 Joules per pulse. The four pulses of a pulse train are separated by 15 seconds of rest between each pulse, and there are 6 days between pulse groups upon discharge , down to a pulse discharge voltage of 2 V. In further embodiments the , batteries have an average internal electrical resistance of no more than 0.2 Ohms at a current …
