Altairnano’s innovative approach centers on replacing conventional graphite anodes with nanostructured lithium-titanate in lithium-ion batteries. This proprietary technology, introduced in 2005, offers several significant advantages. The batteries demonstrate exceptional charging and discharging capabilities, achieving specific power ratings of up to 4000 W/kg and power density exceeding 7,500 W/litre. The company’s LTO-based batteries maintain stable performance through more than 16,000 charge-discharge cycles while retaining 80% of their initial capacity, far surpassing the typical 1,000-cycle lifespan of standard lithium-ion batteries. The technology features superior thermal stability, eliminating thermal runaway risks below 250°C, and operates effectively across wide temperature ranges, making them suitable for demanding applications such as electric vehicles, industrial equipment, grid storage, and military use.
Altairnano’s key product is the nano lithium titanate (nLTO) battery cell, which is designed for high-power applications. These batteries provide exceptional charge/discharge rates, long lifecycle durability, high power density, and enhanced safety features compared to traditional lithium-ion batteries.
Altairnano is engaged in ongoing projects to expand its battery technology applications, including collaborations for electric vehicle powertrains and grid energy storage solutions. These initiatives aim to enhance renewable energy integration and reduce carbon emissions by improving energy storage efficiency and durability.
Altairnano secured $40M in venture funding in 2007 led by J.P. Morgan Securities Inc., plus an additional $7M from undisclosed investors. The company currently operates as a subsidiary of Energy Storage Technology (China) Group Limited.
