The first to discover the principle of fuel cells was the Englishman Sir William Grove (1811~1896), a lawyer and amateur science enthusiast. In an accidental electrolysis experiment in 1839 [Fig. 1(a)], it was observed that when two electrodes in an electrolyzer were connected together [Fig. 1(b)], a current flowed in the opposite direction, consuming both … Read More “Fuel Cells – Overview and Classification of Fuel Cells” »

Comparison of supercapacitors and power batteries Compared with traditional capacitors of the same size, the energy that supercapacitors can store is much greater than that of traditional capacitors, but compared with batteries of the same size, the energy that supercapacitors can store is smaller than that of batteries, but the power performance of supercapacitors is … Read More “Talking about the specific application of super capacitors in electric vehicles” »
Theoretical model of the supercapacitor model The basic principle of electric double-layer capacitors is established based on the capacitance characteristics between the solid-liquid interface. This property was discovered by Helmholtz in 1853. Electric double-layer capacitors store energy through space charges generated on the solid-liquid surface under electrostatic action. This space charge is called the electric … Read More “A detailed explanation of the supercapacitor model” »
At present, many carbon-nickel system supercapacitors are used. Here, the energy storage principle of this new type of supercapacitor is introduced in detail. Two identical carbon electrodes are connected in series in the carbon-nickel system electric double-layer supercapacitor, and the capacity of the entire capacitor can only get half of the capacitance on one electrode. … Read More “Carbon Nickel System Supercapacitor” »
Energy storage mechanism of supercapacitors A supercapacitor is a new type of energy storage element between electrolytic capacitors (capacitors using a thin oxide film as a dielectric) and electrochemical batteries, and its energy storage method is different from that of traditional capacitors. Traditional capacitors are composed of electrodes and a dielectric. The dielectric between the … Read More “Supercapacitors – Detailed explanation of energy storage mechanism and classification of supercapacitors” »
According to the different electrolyte materials used in lithium ion batteries, lithium ion batteries can be divided into two categories: liquid lithium ion batteries (LIB) and polymer lithium ion batteries (LIP). The polymer electrolytes used in polymer lithium ion batteries can be “dry” or “colloid”, and most of them currently use colloid electrolytes.The biggest feature … Read More “Definition of polymer lithium-ion battery” »
