Synthesis of SiOx/C from lignocellulose for lithium ion battery anode applications

Overview

SiOx/C anodes are attracting significant industry interest for lithium-ion battery applications due to their much higher energy density compared to graphite. Currently, SiOx/C anodes are produced on a limited commercial scale using the chemical vapor deposition (CVD) methods. However, the CVD process is costly and unsustainable, limiting the large-scale deployment of SiOx/C in lithium-ion batteries. Lignocellulosic biomass is rich in carbon, and many types also contain silica, making it a promising sustainable feedstock. This PhD project aims to develop low-cost, high-performance SiOx/C materials derived from lignocellulosic biomass for lithium-ion battery anode applications.

Research activities

In this project, you will develop innovative biomass processing strategies to produce nanosilica and porous carbon with tunable properties from lignocellulosic biomass. You will also design advanced approaches to synthesize and assemble SiOx/C composites for high-performance lithium-ion battery anodes.

Outcomes

We expect that the electrochemical performance of the biomass-derived SiOx/C materials will meet or exceed that of SiOx/C produced via conventional CVD methods, enabling more sustainable and scalable lithium-ion battery technologies.

Skills and experience

A background in chemistry or chemical engineering is essential for this PhD project.

Prior research experience in biomass pretreatment and/or electrochemistry is highly desirable.
