AbstractThis proposal describes a superior high-energy density and high-rate, rechargeable, 18650-size cell for Army applications based on a novel, ultrasafe, high-energy, low cost nano-cathode material that is capable of fast recharges and high-rate discharging. The cell also incorporates a new nano-anode material to increase the energy density for both high rates discharging and charging. The unique combination of nano-cathode and nano-anode materials provides exceptionally high-rate capability (>95% of rated capacity at 10 A continuous discharging) and allow conventional electronic circuits to be used for state-of-charge estimation. These characteristics make the cells especially well-suited for the smart, lithium-ion, rechargeable BB-2590 battery. The work proposed here will lead to cells that are a drop-in replacement for cells currently used in the BB-2590 and will lower cost, provide improved safety, and increase rate capability so that fewer BB-2590 packs can be used in applications such as Non-Line of Sight (NLOS) which requires very high power during firing the missile.
