Title: Martin Payne and Lithium-Ion Battery Innovation.

Introduction

Martin Payne is an inventor associated with Avon, Ohio, whose patent work focuses on improving the performance of lithium-ion batteries. His research examines lithium bis(trimethylsilyl) phosphate, or LiTMSP, as a bifunctional electrolyte additive for lithium nickel manganese oxide (LNMO)/graphite cells.

Latest Patents

Payne is associated with 1 patent: “Lithium bis(trimethylsilyl) phosphate as a novel bi-functional additive for lithium ion batteries.” The work reports that adding LiTMSP can improve the cycle performance of LNMO/graphite cells. Its trimethylsilyl group can react with hydrofluoric acid formed when residual water hydrolyzes LiPF₆ in the electrolyte, helping reduce metal-ion dissolution from the electrode.

The research also describes a LiTMSP-derived surface film on the graphite electrode. This film can limit further electrolyte decomposition and damage associated with migrated metal ions, while potentially improving lithium-ion conductivity and reducing electrode resistance. Together, the proposed HF-scavenging and film-forming effects may reduce cell polarization and support improved cycling and rate performance.
