Research Institution
The objective of this proposal is to demonstrate the feasibility of producing a novel nano-engineered anode material that significantly shortens the Li+ diffusion length and enable lithium ion batteries capable of being quickly recharged in less than 15 minutes. A nanostructured electrode will be engineered by adapting template-assisted fabrication of copper nanorod arrays as miniature current collectors and depositing titanate based nano-particles on copper nanorod forest using a simple and inexpensive method of electrochemical deposition. Demonstrate its ability to apply a small laboratory half-cell that can charge in less than 15 minutes without deposition of metallic lithium. A recent study on electrodes with nano-architectured current collectors showed a promising high-rate capacity. Using such electrodes, the researchers demonstrated a factor of six improvements in power density over planar electrodes and an 80% retention of total capacity at 8C rate over 100 cycles. Yardney/Lithion, Inc., a leader in cutting edge Li-ion batteries technology and producers of such high power batteries for variety of commercial, aerospace and military applications, proposes in collaboration with research experts in nano-engineering of materials, at Worcester Polytechnic Institute in Massachusetts, to investigate nano-architectured amorphous TiO2 based anode materials for a new generation rapid recharge lithium ion battery.
