Long Life, High-Performance Battery for Start-Stop Applications04/30/2018
Start-stop micro-HEVs, in which the engine turns off whenever the vehicle isn’t moving while the battery continues to power accessory loads, can provide a low-cost, near term means to mitigate the gasoline waste and the greenhouse gas and pollutant emissions produced by vehicles idling in congested urban traffic. However, lead-acid vehicle batteries are ill-suited for the start-stop application. This Phase I SBIR program demonstrated that a CAM-7® cathode, LTO anode lithium-ion cell technology can meet the USABC 12 V start/stop vehicle battery targets including cold-crank performance, within the weight/volume constraints. Over the course of the program, CAM-7® materials were made, and CAM-7®/LTO coin cells and pouch cells, including 6-series-cell pouch cell pouch cell stacks, were assembled and tested to demonstrate high feasibility for the CAM-7®/LTO cell technology to enable 12V start-stop vehicle batteries meeting USABC goals.
