18 August 2009 - 13:41High Specific Power & High Rate Capability for HEV & PHEV Using Nano Electrodes

Nano-Li4Ti5O12 Based Lithium Ion Battery for HEV and PHEV Application

Dr. Veselin Manev, Director of R&D at Altairnano Inc., will discuss the performance of high specific power and high rate capability cells with nano-Li4Ti5O12 negative electrodes developed in particular for HEV and PHEV application at Lithium Mobile Power 2009. Data for capacity retention during continuous discharge at up to 80C rate corresponding to 45 second cell’s full discharge duration will be displayed. Cycle life in excess of 25,000 cycles, at 8C charge/discharge rate and 100% depth of discharge will be presented.  Particular attention will be paid to the excellent calendar life performance with data revealed from accelerated calendar life testing suggesting capacity fade below 1% after 25 years at room temperature.  In conclusion, results from safety tests performed on these cells showing no safety events will be presented.
