The pressing need for transition to a zero-emission economy drives innovations within electrical energy storage technologies. Batteries and supercapacitors are the main building blocks for electrical energy storage systems crucial for mobile and stationary applications. Frank Lev reports.
While batteries use Faradaic redox reactions to store electrical charge, supercapacitors store electrical charges statically. The most common electric double-layer capacitors (EDLCs) are often called symmetric carbon/carbon supercapacitors because their carbon-based cathodes and anodes are identical.
Continuously evolving energy storage technologies such as batteries and supercapacitors cooperate to borrow certain electrochemical features to improve their performance capabilities. For . . .
