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.
XALT’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 XALT’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.
“These cells combine outstanding fast-charge performance, unparalleled cycle life, long calendar life and the ability to operate over wide temperature ranges,” says Subhash Dhar, XALT CEO. “The 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.”
