Top 10 Supercapacitor Manufacturers in the World
Supercapacitors, also known as ultracapacitors, are high-capacity capacitors with unique advantages, such as high-speed charging, reliable operations, collaborative integration with batteries or fuel cells, etc. True to its name, a supercapacitor has a vast capacitance value, much higher than that of solid-state capacitors, but lower voltage limitations. Thus, a supercapacitor bridges the gap between electrolytic capacitors and rechargeable batteries.
The world is fast realizing the significance and prowess of supercapacitors. The global supercapacitor market is expected to expand from USD 472 million in 2022 to USD 912 million by 2027, which is an apt testament to their current status. Their large-scale adoption across industries such as automotive, grid infrastructure, wind turbines, intelligent wearables, EVs, and electronics is fueling this jarring growth.
