Title: Venkata Ak Adiraju and Lithium-Ion Battery Innovation.

Introduction

Venkata Ak Adiraju is an inventor associated with Warwick, Rhode Island, whose work focuses on improving lithium-ion battery performance. His research examines lithium bis(trimethylsilyl) phosphate, or LiTMSP, as a bifunctional electrolyte additive for lithium-ion batteries, particularly LNMO/graphite cells.

Latest Patents

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

The research also describes a protective surface film formed from LiTMSP on the graphite electrode. This film can limit further electrolyte decomposition and damage associated with migrated metal ions. The reported reduction in electrode resistance and cell polarization may also support improved rate and cycle performance.
