Arsenault – USABC, Judes – JCI III.A.4 Advanced High-Performance Batteries for PEV Applications in late 2013. This $4.1 million, 2 year follow-on program builds on the first generation platform. The theme of this program is to achieve a major energy density improvement of the cell. Between the conclusion of the previous program and the kick-off of this program, the upward march in energy density continued, through continuous improvements made in process, materials and mechanical design. This improvement is seen in Figure III - 9. Figure III - 9: Energy density roadmap Approach The objective of the program is to increase the energy density of the cell technology and drive down the cost to capacity ratio, either directly (with increased mAh/g, reduced BSF and cost) or indirectly (with improved critical enablers: life and abuse tolerance). The focus is on active materials that fall midway on the ‘state-of-the-art’ to ‘high-risk’ continuum, striving to exploit their full, unrealized potential through concerted material, process, and mechanical design innovation. Specifically, the family of LiNixCoyMnzO2 (where x>1/3) is targeted for the positive electrode coupled with a graphitic negative material. Module and system development have been excluded from the program to focus resources on closing the gap in cell technology. If achieved, derivative system-level benefits of cost, volume and mass reduction will be realized and gap chart targets will be met. Increased energy density is being pursued on four discrete levels:1) active material specific capacity increase, 2) electrode composition (increased active material to inactive constituents ratio, 3) electrode densification, and 4) maximizing space occupied by the electrode coil in the cell envelope and increasing coated electrode width. The following five improvement areas form the framework of the program, and all converge toward the central program goal of reducing the $/kWh metric. Higher Energy Density Materials. JCI is focusing on high-nickel NMC cathode materials. Compared to the baseline NMC111, high-nickel materials exhibit reduced structural and thermal stability, manifested by accelerated aging and lower abuse tolerance. To address this, stabilized active materials (doped, coated, and / or surface treated) from six global suppliers were evaluated. Lithium-rich layered-layered cathode materials are also being evaluated to identify the main barriers that need to be overcome prior to commercialization. Electrode Processing Optimization. Novel slurry processing techniques are being studied with two objectives: 1) reducing the quantity of N-Methyl Pyrrolidinone (NMP) solvent used in the positive electrode manufacturing process by 18-22% (result: cost reduction) and 2) improving the electrode handling through calendaring and winding to support electrode densification (result: increase in cell energy density). Drivers for the amount of solvent, conductive agent and binder used in the current process are intimately linked to the type of mixing applied. JCI’s process uses the classic industry approach for solids dispersion. Alternative methods of first compounding or pre-mixing active material with the conductive agent are being explored as paths to solvent reduction and associated increase in active to inactive material ratios and energy density.
