U.S. ARMY MANTECH»Click to View/ Print Brochure

OBJECTIVE / SOLUTION

The objective of this program scale up ARL research success in 5 V Li-ion to produce high energy density safe Li-ion batteries by developing the manufacturing process for the 5 V materials & prototyping Li-ion batteries that are tolerant to abuse and of higher energy density than currently available.

Achievements

• Forged a partnership between ARL scientists and industry to drive this revolutionary battery technology toward maturity

Benefits

• 40% greater energy density than safe LiFePO4 Li-ion battery chemistry with uncompromised safety
• 30% greater energy density unsafe LiCoO2 Li-ion battery chemistry
• Reduction in materials cost of cathode material by up to 50%
• Availability of high energy and safe Li-ion cell chemistry to be used across multiple Army platforms including combat vehicles, soldier power, aircraft, communications and other electronic devices
• Improved performance across all platforms where Li-ion is used upon transition to Li-ion cell manufacturers. Including combat vehicles, soldier power, aircraft.

Transition and Weapon System / Secondary Items Impacted

• Joint Light Tactical Vehicle (JLTV) Targeted Transition
• Potential future transitions to multiple DoD platforms using Li-ion batteries
