Title of the Licentiate Thesis

A scalable furnace technique to grow silicon nanoparticles for high performance Li-ion battery anodes

Abstract

Lithium-ion batteries are one of the key technologies to address the global climate challenge. Higher battery capacity could also be seen as indirectly influencing the entire value chain. One way to increase capacity is to add silicon to the graphite anode, since silicon can store much more lithium ions than graphite. Several high-performance schemes utilizing silicon nano solutions have been demonstrated. However, industrial-scale implementation of these solutions still poses a challenge. In this thesis I present a novel scalable furnace technique to create silicon nanoparticles attached to the nanographite flakes. The novel furnace technique allows compatibility with already established industrial-scale electrode manufacturing techniques, presenting itself as a promising strategy for engineering electrodes with endurable performance.
