Silicon Anode Battery Market Poised to Witness Significant Growth due to Increasing Adoption in Electric Vehicles

Posted 2024-01-18 11:37:06

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.

SWOT Analysis

Strength: Silicon has a high specific capacity compared to graphite, allowing for more energy in a battery of the same size. It can store up to 10 times more lithium by volume. However, silicon is able to accommodate lithium atoms in its crystal structures during charging, resulting in large volume changes. This makes the material unstable and reduces its lifespan over many cycles.

Weakness: Silicon anodes experience huge volume changes (around 300%) during battery operation, which causes the anode to fracture and lose electrical contact. The solid electrolyte interphase (SEI) layer also breaks down easily due to the large volume changes, resulting in continuous consumption of electrolyte and capacity fade.

Opportunity: The use of novel nanostructures and composites to accommodate the large volume changes of silicon during cycling. This includes nanowires, nanoparticles, thin films and composites with conductive agents that enable stress relaxation. Many companies are also developing coatings and electrolytes optimized for silicon to stabilize the SEI layer.

Threats: Competing lithium-ion battery technologies such as lithium metal and solid-state designs. These aim to provide higher energy densities than silicon anodes while avoiding some of the stability issues. Slower than expected commercialization of EVs could also reduce demand.

Key Takeaways:

The Global Silicon Anode Battery Market Demand is expected to witness high growth over the forecast period driven by silicon’s potential to significantly improve lithium-ion battery performance. With the rapid adoption of EVs, there is a growing need for energy-dense batteries to increase vehicle range. Silicon’s ability to store roughly 10 times the lithium of graphite makes it an appealing graphite replacement in anodes.

Regional analysis: The Asia Pacific region currently dominates the global silicon anode battery market and is expected to continue leading over the forecast period. This is due to the large production and sales of consumer electronics and electric vehicles in China. For example, over 60% of lithium-ion battery production occurs in China. Countries like South Korea and Japan are also major battery and EV producers. Meanwhile, Europe and North America are witnessing faster adoption of EVs and stationary storage, fueling regional demand for silicon anode batteries.

Key players operating in the silicon anode battery market are Shanghai Putailai New Energy Technology Co., Ltd., Enevate Corporation, Panasonic Corporation, XG Sciences Inc., ONED Material, and Amprius Technologies. Amprius is a leader in silicon nanowire anode technology and supplies batteries to drone makers. Panasonic provides lithium-ion battery solutions for Tesla and other automakers. Enevate’s silicon-dominant anode design is being commercialized with Samsung SDI.
