Title: A New Class of Low-Cost, High-Capacity Cathode Materials for Next Generation Rechargeable Lithium-ion Batteries

Abstract

New, cost-effective developments in battery materials/battery chemistry are the key to the future of the $30+ billion lithium-ion battery industry. For the United States to become the world leader in electric vehicle manufacturing, the cost and performance of lithium-ion batteries must be improved. The US Department of Energy has set stringent goals that no one has yet met. Cathode materials are the single most expensive component and the largest volume constituent of a lithium-ion battery (>20% of the cost, >1/3 of the cell volume). Thus, cathode performance and cost are the key determinants of the overall battery’s performance and cost – and the focus of NextGen Battery Technologies, LLC’s Phase I SBIR effort. During the course of the project, NextGen developed a patent-pending high-capacity, high-power, low-cost advanced cathode material that minimizes (and potentially eliminates) the use of high-cost metals (cobalt) in rechargeable lithium-ion batteries. Capacity is comparable to state-of-the-art materials, but at potentially 1/2 the cost. The material can be used at high-rate (rapid charge/discharge), is stable over a broad voltage range, and is inherently safe. The synthesis used proven, low-cost, scaled processes, and the performance was demonstrated at the half-cell, coin-cell, and pouch-cell levels. Based on the measured data,more » NextGen predicts that the DOE performance and cost goals may be met in scaled-up versions of the cells.« less
