Title: Demonstration of a Novel Process to Produce Nickel-rich NMC Cathodes for Electric Drive Vehicle Batteries

Abstract

During Phase I, Ge Solartech demonstrated that nickel-rich NMC cathode materials can be synthesized directly from pure metals via a novel solid-state process that avoids time and energy-consuming steps in the conventional hydroxide coprecipitation process. The company developed a highly efficient protocol for producing precursors from base metals with low cost organic/inorganic acids. By using those precursors, various NMC cathode materials were successfully synthesized. Those materials exhibited a highly ordered structure and good crystallinity, and demonstrated good half-cell performances. The degree of cation mixing can be tailored by synthesis conditions, including reaction temperatures and duration. What is more, by utilizing this technology, a new element has been successfully integrated into the NMC system, and the highly ordered layered structure has persisted. This newly discovered system could offer dramatically reduced material cost and improved material performance. This sets the stage for reducing production costs, a key objective of this initiative. During Phase I we successfully addressed major objectives : (1) Develop a novel synthetic process to produce precursors directly from pure metals; (2) Develop a solid-state synthesis process capable of reducing NMC manufacture cost by 70%; (3) Understand/optimize electrode structures and performance that will enable high energy density nickel-rich cathode materialmore » and (4) Demonstrate that full battery cells can be made from high performance cathodes, Si-graphite composite anodes and thick electrode technology. Due to the delay in this project, full battery cell work (Objective 4) was waived. Each of these are discussed below.« less
