New and Improved Lithium-Ion Battery, Phase I

Completed Technology Project

Project Introduction

New and Improved Lithium-Ion Battery, Phase I
This project is a partnership effort between American Energy Technologies Company (Illinois), Yardney Technical Products (Connecticut) and A.J. Drexel Nanotechnology Institute of Drexel University (Pennsylvania). The proposing team seeks to demonstrate tangible improvement in the performance of Lithium-Ion batteries by way of increasing their specific energy density beyond 300 Wh/kg at C/2 in the range of temperatures, at a minimum, from 60oC to 0oC. The battery will use newly developed Silicon-doped, stabilized graphitic anode; Lithiated mixed oxide cathode, in its turn, doped with nano-sized cycling stability-enhancing additives; and an innovative inherently safe electrolyte system based on ionic liquids. Special focus of the development effort shall be directed towards creation of scaleable Si-doped carbon material for the battery anode. Cell optimization effort will focus on methodic rebalancing of the classic anode to cathode ratios, by devising unique, highly efficient cathode of increased thickness in support of operation of thin anode, whose specific capacity will vary from 300 to 2,000 Ah/kg at C/2.
