Nanophosphate® Lithium Iron Phosphate Battery Technology

A123’s high-performance Nanophosphate® lithium iron phosphate (LiFePO4) battery technology delivers high power and energy density combined with excellent safety performance and extensive cycle life in a lighter weight, more compact package. Our products have low capacity loss and impedance growth over time, allowing our systems to meet end-of-life power and energy requirements with minimal pack oversizing.

Nanophosphate in action

Powered by over two megawatts of A123's lithium ion batteries, the all-electric Venturi Buckeye Bullet sets a new land-speed record with an average top speed of 341 miles per hour. This shatters their previous world record that was also powered by A123.

The Nanophosphate Advantage

Power: High charge and discharge rates

Better performance and efficiency are achieved through high charge and discharge rates. Nanophosphate is a positive electrode material of remarkable rate capability, critical to high power systems. Our high power products are able to pulse at discharge rates as high as 100C and deliver superior power by weight or volume in a cost effective solution. With their low impedance and thermally conductive design, A123 high power cells can be continuously discharged at a 35C rate, a marked improvement over other rechargeable battery alternatives, and have consistent power over wide state of charge (SOC) range.

Safety: Superior abuse tolerance

Safety begins with chemistry. A123’s 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.

Life: Long battery life for both deep & shallow cycling

A123’s ltihium iron phosphate technology delivers exceptional calendar and cycle life. At low rates our cells can deliver thousands of cycles at 100% depth of discharge (DOD), a feat unmatched by most commercial lithium ion cells. Even when cycled at 10C discharge rates, our cells deliver in excess of 1,000 full DOD cycles. Not only does A123’s technology retain its energy, it also retains its power capability.
