Silicon anode batteries are lithium-ion batteries that utilize silicon as the anode material instead of the conventional graphite. Compared to graphite, silicon holds a much higher specific capacity allowing it to store more lithium ions and thus deliver higher energy density. This makes silicon anode batteries ideal for powering miniature consumer electronic devices such as smartphones, wearables, wireless earbuds, and others. Some key manufacturers are utilizing nanotechnology to overcome the issues associated with silicon anodes like swelling and cracking during charge-discharge cycles. Silicon particles are encapsulated within a carbon or silicon-carbon composite that maintains the structural integrity even with volume changes during lithiation/delithiation.
The global silicon anode battery market is estimated to be valued at US$ 370.47 Mn in 2023 and is expected to exhibit a CAGR of 4.0% over the forecast period 2023 to 2030, as highlighted in a new report published by Coherent Market Insights.
One of the primary drivers fueling the growth of the silicon anode battery market is the miniaturization of consumer electronic devices. Smartphones, smartwatches, fitness bands, and other portable devices are becoming increasingly smaller in size with each new iteration while packing in more advanced features and capabilities. This necessitates the development of high energy density batteries that can power these miniature devices for longer duration without increasing their footprint. The higher energy storage capacity of silicon anode batteries compared to conventional lithium-ion batteries makes them well-suited to meet this demand. Additionally, continuous R&D efforts focused on resolving issues related to silicon’s volumetric expansion during charging are further enhancing its practical feasibility for commercial and consumer applications. Various nanotechnologies are enabling more stable encapsulation of silicon particles and carbon-coating is shown to improve cycling stability. Rise in demand for miniature electronics as well as technological advancements to improve cycle-life of silicon anodes are projected to propel the silicon anode battery market growth over the forecast period.
For the silicon anode battery market, there are two primary segments dominating the industry- silicon monoxide anodes and silicon-carbon composite anodes. The silicon-carbon composite anodes segment accounts for more than 60% of the total market share due to its excellent cycle life performance and higher energy density compared to traditional graphite anodes. Within this segment, silicon microparticles mixed with carbon nanotubes as anode materials have seen increased adoption owing to superior diffusion pathways that reduces capacity degradation on continuous charging and discharging.
