XALT Energy, a manufacturer of prismatic, large-format battery cells and packs, has launched a new Lithium Titanium Oxide (LTO) cell that it says has achieved better cycle life performance over a wider range of operating conditions than any lithium-ion cell ever built.
XALTâ€™s Li-ion LTO cell offers specific energy greater than 76 wh/kg, and specific power greater than 1,400 w/kg. Cycle life (to 80% of rated capacity) can be as much as 110,000 cycles, depending on the depth of discharge.
The new cells are produced in XALTâ€™s manufacturing facility in Midland, Michigan, which is so highly automated that human hands touch the product only during a final inspection before packaging. They are currently being used in electric buses, where they are charged multiple times daily at high rates.
â€œThese cells combine outstanding fast-charge performance, unparalleled cycle life, long calendar life and the ability to operate over wide temperature ranges,â€ says Subhash Dhar, XALT CEO. â€œThe cells exhibit low, stable impedance, which minimizes heat generation in aggressive high-rate applications with fast charging capability. It easily fits applications requiring extremely high power-to-energy ratios and where safety is critical.â€
