Electrochemical Supercapacitor
Design, Fabrication, and Operation
5.1 Introduction
The design, operation, and manufacturing of electrochemical ES devices
are important in supercapacitor technologies. However, the industry
advancements of electrode fabrication and materials design largely remain
proprietary to individual developers and manufacturers. Ensuring the
security of their intellectual property is necessary to maintain a competitive edge in the fast growing field of energy storage. As a result, a
thorough guide containing specific details of current advancements in
electrochemical supercapacitor materials, fabrication, and design remains
largely inaccessible. Therefore, the discussion about these commercial
technologies is limited by information that is freely accessible to the public sector.
The performance of electrochemical supercapacitors is strongly dependent
on the design and integration of active electrodes, electrolytes, and current
collectors. Many of their production features are similar to the processes
for manufacturing batteries. Both ES devices and batteries require electrolyte accommodations, separators, proper sealings, and casings. Therefore,
supercapacitor manufacturers apply battery engineering and production
machinery when designing and producing supercapacitors to save money
and improve performance.
Supercapacitor technology has advanced in recent decades and devices are
classified as economically viable and unviable options. In general, academic
endeavors allow the pursuit of both options, but commercial research and
development (R&D) firms are not interested in unviable research. As a result,
much of their focus has centered on improving supercapacitor performance
and developing inexpensive materials for mass production. Commercial
R&D is driven by the need to be innovative, decrease manufacturing costs
that limit competition, and improve sales. In an effort to achieve these goals,
the electrode and electrolyte materials required for ESs have been identified
as major challenges, as discussed in Chapter 4.
