Title: Nano-Engineered Materials for Rapid Rechargeable Space Rated Advanced Li-Ion Batteries
Agency: NASA
Contract: NNJ08JA67C
Award Amount: $597,892.00


Lithium-ion (Li-ion) batteries are attractive candidates for use as power sources in aerospace applications because they have high specific energy, energy density and long cycle life. However, conventional Li-ion batteries experience loss of capacity and increased impedance and poor cycle life when they are charged/discharged at high rates over C-rate. These problems are magnified at low temperature operation. The limitations in the high rate capability of Li-ion batteries are mainly caused by slow solid-state diffusion of Li+ within the electrode materials Yardney/Lithion Inc., the world leader in cutting edge Li-ion battery technology proposes to investigate new non-toxic nano-engineered electrodes that significantly shortens the Li+ diffusion length within the electrode materials and increases the rate capability of Li-ion batteries. The goal of this Phase II project is to manufacture rapid recharge Li-ion battery for aerospace application. Yardney will manufacture 5 prototype cells capable of recharge at less than 15 min at room temperature. During the phase I we found that the nanoengineered anode showed excellent rate capabilities compared to planar electrode. Nanoarchitectured current collector provides higher safety due to large surface area contact with the active material and that acts as heat sink in high rate applications and also lower impedance.
