XALT Energy introduces high-performance lithium titanate cell technology; electric bus applications
10 September 2016
XALT Energy has introduced a high-performance 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 pairs the LTO anode with an NMC cathode in a prismatic, stacked parallel plate electrode design offering greater reliability, safety, life and fast charge capability. The 60 Ah, 2.2 V cell features high power capability (5C/10C), a wide operating range (-40 °C to +55 °C), low impedance and heat generation, and is capable of a less than 10-minute fast charge.
These cells combine outstanding fast-charge performance, unparalleled cycle life, long calendar life and the ability to operate over wide temperature ranges. The cells exhibit low, stable impedance which minimize heat generation in aggressive high-rate applications with fast charging capability. They easily fit applications requiring extremely high power-to-energy ratios and where safety is critical.—Subhash Dhar, XALT CEO
One of the applications for XALT’s LTO chemistry is in the commercial transportation market, specifically in electric buses. XALT’s LTO cell offers the benefit of being able to fast charge without significantly impacting cycle life.
The Li-Ion LTO cells are produced in XALT’s state-of-the-art manufacturing facility in Midland, Michigan. XALT’s flexible manufacturing facility offers a highly automated process where human hands only touch the product during final inspection before packaging. The new cells are currently used in pure electric buses for multiple high rate charges on a daily basis.
