A New Li Anode Technology for Improved Performance, Phase I

Completed Technology Project

Project Introduction

A New Li Anode Technology for Improved Performance, Phase I
Lithium (Li) metal-based rechargeable batteries have many advantages over Li-ion systems including significantly higher energy density, lower cost, and the option of using positive electrode materials that do not have to be pre-lithiated. Unfortunately, Li metal electrodes form metal dendrites upon cycling, compromising battery safety and limiting cell life. TH Chem, Inc. (THC) proposes to team with Sandia National Laboratories (SNL) and New Mexico Institute of Mining and Technologies (NMT) to develop a novel, low-cost approach to stabilization of Li metal anodes for high performance rechargeable Li batteries. Novel electrolyte additives will be selected and utilized in Li cell electrolyte systems, promoting formation of protective coating on Li metal anodes for improved cycle and safety performance. In Phase I, electrolyte additives will be selected and studied trough assembly and electrochemical evaluation of Li cells. The PI and his team have extensive experience in lithium battery chemistries and technologies. More »
