Title: STTR Phase II: Using Nanoparticle Oxide Coatings to Extend Cycle Life of Cathode Materials in Lithium-Ion Batteries
Agency: NSF
Contract: 1156229
Award Amount: $499,998.00
 

Abstract:

This Small Business Innovation Research (SBIR) Phase II project seeks to increase the cycle life of cathode materials used in lithium-ion batteries by a factor of ten in high-temperature applications by applying protective nanoporous ceramic coatings. SolRayo will investigate the effects that changing several variables that control the nanoporous structure of ceramic coatings have on the cycle life of cathode materials. Such variables include the amount or thickness of the coating, the pH of the suspension of the coating material, the deposition of layers of different ceramic materials on the cathodes, and different methods for depositing the coatings on the cathodes. The materials to be investigated will include TiO2, ZrO2 and others proposed by our industrial partner. The broader impacts of this research are that, if successful, this project will improve the cycle life of lithium-ion batteries and allow inherently safer and less expensive materials to be employed. Although lithium-ion batteries have gained wide acceptance in consumer electronic products, their use in other markets has been limited by their lifetimes and safety concerns, particularly in applications at higher temperatures. Improving the lifetime and safety of the materials used in these batteries will enhance their market penetration. Preliminary cost estimates indicate that licensing the coated materials to industry could provide approximately $100 million annually in royalties on sales. This work will also benefit the nation by improving our understanding of nanoparticle coating techniques suitable for a variety of energy storage applications.
