Bio
Solomon Oyakhire is a PhD candidate in the department of chemical engineering. He received his BSc in chemical engineering at the University of Lagos in Nigeria before starting his PhD in chemical engineering as a Knight-Hennessy scholar. He is primarily interested in the scientific and economic facets required for accelerating the deployment of renewable energy technologies. Prior to Stanford, he carried out research on phase change materials applied in solar thermal heating systems at the University of Lagos and worked as a technology consultant at KPMG. By operating with frameworks that he gathered from research and consulting environs, he is currently working on developing high energy density batteries with practical applications in the grid and electric vehicles.

Suspension electrolyte with modified Li+ solvation environment for lithium metal batteries.

Abstract
Designing a stable solid-electrolyte interphase on a Li anode is imperative to developing reliable Li metal batteries. Herein, we report a suspension electrolyte design that modifies the Li+ solvation environment in liquid electrolytes and creates inorganic-rich solid-electrolyte interphases on Li. Li2O nanoparticles suspended in liquid electrolytes were investigated as a proof of concept. Through theoretical and empirical analyses of Li2O suspension electrolytes, the roles played by Li2O in the liquid electrolyte and solid-electrolyte interphases of the Li anode are elucidated. Also, the suspension electrolyte design is applied in conventional and state-of-the-art high-performance electrolytes to demonstrate its applicability. Based on electrochemical analyses, improved Coulombic efficiency (up to ~99.7%), reduced Li nucleation overpotential, stabilized Li interphases and prolonged cycle life of anode-free cells (~70 cycles at 80% of initial capacity) were achieved with the suspension electrolytes. We expect this design principle and our findings to be expanded into developing electrolytes and solid-electrolyte interphases for Li metal batteries.
