These have high cathode potentials and push the electrolyte and anode SEI layer towards breakdown. The cost of these cells are also pushed to high volume at moderate quality. HEV's and PHEV's require high power density cells and new nano iron-phosphate and other stabile chemistries are being persued. Also cost and quality will be of key concern. Safety is #1.
