According to recent research from Talence, France, "Supercapacitors (SCs), which are also known as ultracapacitors, are commonly based on porous activated carbon electrodes and electrostatic charge-storage mechanisms. Carbon electrodes are supposed to be chemically and electrochemically inert, and the electrostatic nature of the charge-storage mechanism is highly reversible."
"These properties should assure that SCs have an infinite shelf life. However, in practice, SC cells exhibit performance fading when they are used for months. The purpose of this paper is to compare the performance fading of SCs in two types of tests. The first accelerated test is the ...
