Silicon is an ideal anode material for batteries due to its high theoretical capacity which is about 10 times greater than traditional graphite anodes. Silicon anode batteries can provide longer runtimes and faster charging compared to lithium-ion graphite batteries. However, issues like particle cracking and loss of capacity have hindered its commercial use. To overcome these challenges, continuous research on silicon material engineering and battery component fabrication is being conducted. Advancements in 3D silicon structures, silicon-carbon composites, solid electrolyte interface coatings and other material technologies have significantly improved the cycle life and stability of silicon anode batteries.
Market key trends:
Advancements in silicon material design and engineering such as silicon nanowires, silicon microparticles, silicon-carbon composites etc are enabling long and stable battery cycling by addressing issues like silicon particle expansion and contraction during charge-discharge cycles. Companies are focusing on developing novel 3D structured silicon anodes with carbon or ceramic additives which can accommodate the large volume change of silicon during lithiation-delithiation without degradation. This is positively impacting the performance of silicon anode batteries and their acceptance in various applications.
