Abstract
Batteries with particularly high energy capacity and low internal impedance have been described herein. The batteries can exhibit extraordinary long cycling with acceptable low amounts of fade. Pouch batteries using high specific capacity lithium rich metal oxide as positive electrode material combined with graphitic carbon anode can reach an energy density of at least about 180 Wh/kg at a rate of C/3 from 4.35V to 2V at room temperature while having a room temperature areas specific DC resistance of no more than about 75 ohms-cmat 20% SOC based on a full charge to 4.35V. High specific capacity lithium rich metal oxide with specific stoichiometry ranges used in these batteries are disclosed.
