The Sandia utility PSOC cycle-life testing has identified a number of battery technologies with good Utility PSOC cycle-life, such as: UltraBattery (carbon enhanced VRLA with supercap) - up to 4C rate，East Penn (carbon enhanced large format VRLA) - up to 1C rate，Li-ion (Li-FePOJ - up to 4C rate，C&O CPV (Sb+Selenium large format vented) - up to 0.5C rate，The new carbon enhanced negative electrodes in VRLA batteries have dramatically improved utility PSOC cycle-life up to a factor of 10. The new Li-ion (Li-FePO_4) battery technology proposed for hybrid electric vehicles is comparable in utility PSOC cycle-life to the new carbon enhanced VRLA batteries. Future work will include completion of testing and may include an energy storage system implementation - such as the wind system at Condon BPA wind farm and/or other demonstrations.
