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.

The state-of-the-art Li-ion battery technology is based on processing of lithium transition metal oxides, and graphite powder, and use of liquid organic electrolytes. It has shown limited room for further performance improvements in terms of energy density, cycle and calendar life, abuse tolerance and cost. This has heavily hindered the advancements of NASA's future space missions that need rechargeable batteries with higher energy density, longer life, and excellent abuse tolerance. In the commercial sector of electrical vehicles (EVs) and hybrid electric vehicles (HEVs), there are also urgent needs for rechargeable batteries with significantly higher performance characteristics that appear beyond the potential of current Li-ion system. TH Chem, Inc. (THC) proposes to team with New Mexico Institute of Mining and Technology (NMT) to develop a new, all-solid-state Li-ion technology for NASA's future space missions that require rechargeable batteries capable of higher energy density (>200 Wh/kg), longer cycle life (>50,000 cycles), extended operation temperatures and radiation tolerance. The new battery system is based on development of a novel, all-solid-state, 3-dimmensional (D) battery design that exploits the full potentials of the electrode and electrolyte materials. In Phase I, THC will demonstrate the feasibility of the new battery technology by preparation of the proposed all-solid-state 3-D batteries via processing of electrode and electrolyte precursors, followed by electrochemical evaluation of the test cells. The concept of the new electrochemical system will be demonstrated. THC and its team have extensive experience in advanced rechargeable battery chemistries and technologies.
