Principle of Hybrid Super Capacitor
Hybrid structure of HSC
Hybrid Super Capacitors (HSC) have a hybrid structure that uses the same activated carbon as electric double layer capacitors for the positive electrode and the same carbon as lithium-ion batteries for the negative electrode. Due to such a structure and advanced pre-doping technology, we have realized performance that combines the advantages of both at a high level.
High capacitance by pre-doping and its principle
By pre-doping lithium ions from metallic lithium to the negative electrode, the potential of the negative electrode was lowered, enabling high cell voltage. At the same time, the positive electrode achieves higher capacity by adsorbing and desorbing anions at 3V or more and lithium ions at 3V or less.
