Title: A Novel Electrode Architecture Enabling Low-Cost, High-Energy Automotive Lithium-Ion Batteries- Final Technical Report

Abstract

The United States Department of Energy has a goal of reducing the production cost of electric vehicle batteries to $80/kWh, increasing electric vehicle range to 300 miles, and reducing charging time to 15 minutes or less. In order to meet battery cost and driving range targets, the research community has focused on increasing the energy density of lithium-ion cells, primarily through increasing electrode thickness. However, thick electrodes must be charged slowly in order to avoid damaging the battery. Alternative anode materials such as lithium titanate, silicon, and lithium metal have been explored as a replacement for traditional graphite anodes, however none meet the performance requirements of electric vehicles. The use of high levels of Saratoga Energy’s novel and low-cost carbon nanotubes in conventional (thick) graphite anodes has enabled the solution to this problem while simultaneously satisfying the other requirements of energy density, cost, cycle life and safety.
