Technical Barriers The main challenge of developing a 12V Li-ion Start-Stop battery is to combine superior low temperature performance enabling cold-cranking and long elevated temperature cycle life in a competitively priced system. Leyden is basing its development on commercially available LTO and LMO materials, which are surface-treated in-house and then assembled and tested in pouch cell prototypes. Electrolyte development under this program requires formulation of the solvent system and additive package. Dow Kokam, our cell manufacturing partner, will assemble the electrodes coated at Leyden into 20Ah cells at no cost to USABC. Flextronics, our pack manufacturing partner, will develop and assemble 12V battery “A” prototypes with balancing circuitry. Technical Targets Develop an LTO-LMO cell that meets USABC 12V Start-Stop performance targets. Most important targets are -30°C cold-cranking and 30°C 450k cycle life. Scale up the coating capability at Leyden and produce anodes and cathodes for the deliverables. Design and assemble 20Ah cells at Dow Kokam facility for USABC deliverables. Develop pack design and balancing circuitry for 12V “A” prototype pack at Flextronics. Deliver up to 50 20Ah cells and three 12V packs to USABC at the end of the program Accomplishments Met USABC -30°C cold-cracking targets at 100% and 50% SOC in 2.2Ah prototypes and 20Ah cells. Projecting >450k USABC shallow cycles at 30°C with the latest 2.2Ah prototype cells. Developed and evaluated 15+ surface treatments to improve high temperature calendar and cycle life of LTO-LMO cells. Delivered requested total of 28 prototypes cells for evaluation to ANL and NREL. Designed and built first 20Ah cells at Dow Kokam Designed a balancing circuitry and assembled first 40Ah 12V prototype packs at Flextronics. Introduction Leyden Energy is developing an affordable, advanced lithium-ion 12 V Start-Stop battery to meet performance, life and cost targets of the USABC’s RFP for “Development Of Advanced High-Performance Batteries For 12V Start-Stop Vehicle Applications”. Leyden is engaging with a high volume cell manufacturer (Dow Kokam) and a capable pack manufacturer (Flextronics) to leverage their respective expertise and resources to address technical challenges and advance low cost, domestic manufacturing. The key elements of our program include: Use of an LTO/LMO couple with Leyden’s Li- imidetm electrolyte to enable a system that meets target capacity, cold cranking power, cycle life, calendar life and price targets. Advancement of Leyden’s technical foundation and leveraging of Dow Kokam’s investment in large volume, domestic lithium- ion manufacturing. Utilization of an innovative cell and battery design to result in a lower weight and lower volume system, approximately 7.2 kg and 6 liters.
