Altair Nanotechnologies, Inc. is an American company specializing in the development, manufacturing, and sale of advanced energy storage systems, primarily utilizing proprietary nanotechnology. Headquartered in Reno, Nevada, the company???s core business centers on its unique nano-structured lithium titanate oxide (nLTO) materials and the resulting high-power battery and energy storage solutions. The company's operations are divided into two main business segments: the Power and Energy Group (PEG), which is the primary focus for corporate development, and an All Others group, which historically encompassed former life sciences and performance materials interests. Altair Nanotechnologies functions as a manufacturer and retailer of its nano-structured batteries and related systems, serving critical sectors where high-performance, rapid-charging, and extended life are paramount.
Core Technology and Operations
The foundational technology of Altair Nanotechnologies is its nano lithium titanate (nLTO) material, which is processed using nanoscale techniques. This material is utilized as the anode in its advanced lithium-ion batteries, a key differentiator from conventional lithium-ion batteries that typically use graphite anodes. The nLTO material forms a spinel structure, which imparts superior characteristics to the resulting battery systems.
The advantages of Altair???s nLTO battery systems are fundamental to the company???s market positioning:
* Safety and Thermal Stability: The technology significantly improves safety, as the nLTO electrodes do not experience thermal runaway until temperatures below 250°C, a marked improvement over conventional lithium-ion batteries, which can fail catastrophically above 130°C.
* Ultra-Rapid Charging and Discharging: The nano-structured material enables a high rate of power density, allowing for extremely fast charge and discharge cycles.
* Extended Cycle Life: The nLTO system offers a significantly longer cycle life compared to traditional lithium-ion batteries.
* Wide Operating Temperature Range: The batteries maintain performance and can be recharged in extreme temperatures, such as retaining 90 percent of room temperature charge retention at minus 30°C, a capability often unachievable with conventional lithium batteries.
The company leverages these attributes to target applications that require high power, long life, and performance at temperature extremes, such as in the electric grid, transportation (especially medium- to heavy-duty commercial vehicles), and industrial applications.
