NANOPHOSPHATE

Technology

Safety begins with chemistry. A123 Systems’ Nanophosphate® is stable chemically, which provides the foundation for safe systems while meeting the most demanding customer requirements. Multiple layers of protection are employed at the chemistry, cell and system level to achieve an energy storage solution with superior safety and abuse tolerance compared to metal oxide lithium-ion chemistries.

The Nanophosphate® Advantage

Superior power by weight or volume in a cost effective solution	Nanophosphate® is stable chemically, providing the foundation for safe systems	Excellent calendar and cycle life with consistent performance over extended use	Higher useable energy means greater battery utilization and lower cost
Fast charge capable Enables smaller, lighter battery pack Consistent power over wide state of charge (SOC) range for greater pack utilization	Superior safety and abuse tolerance compared to metal oxide lithium ion chemistries Independently validated by National Labs and multiple customers Multiple layers of protection at the chemistry, cell and system level mitigates risk	Nanophosphate® technology retains performance enabling less pack oversizing At low rates our cells can deliver thousands of cycles at 100% depth of discharge Energy and power capability retained over extended life High rate and deep cycling capabilities mean greater battery utilization	Deeper cycling and a wider usable SOC range means higher usable energy; more of the battery’s energy can actually be utilized in the application. High usable energy enables less pack oversizing for superior price-performance
