Lithium-ion capacitor (LIC) is a kind of electric energy storage device with both high energy density and high power density characteristics and can achieve high current charge and discharge.
It combines the advantages of lithium batteries and supercapacitors/EDLC, and integrates many excellent features such as high power, high energy, long life, high safety,
wide temperature range, high reliability, and low cost.
Lithium-ion capacitors are similar in structure to supercapacitors, but the anode uses a carbon material pre-doped with lithium ions,
and the cathode usually uses activated carbon used in supercapacitors.
This pre-doping process reduces the potential of the anode and allows a relatively high output voltage.
Jinpei lithium-ion capacitors with independent intellectual property rights patent No.ZL 202221279740X, widely used in EV/robot/ solar energy and other fields
The positioning or performance of our product (Jinpei LIC) is between lithium batteries and super capacitors,which can effectively replace LIB.
The history of lithium-ion capacitors can be traced back to 1981, when Dr. Yamabe of Kyoto University and KaneboCo. By pyrolyzing phenolic resins at 400-700°C, Dr. Yata created a material called PAS (polyene semiconductor).
This amorphous carbonaceous material performs well as an electrode in high energy density rechargeable devices. KaneboCo applied for a patent in the early 1980s and began efforts to commercialize PAS capacitors and lithium-ion capacitors (Lics).
PAS capacitors were first used in 1986 and LIC capacitors in 1991. Although early research has focused on improving the performance and cycle life of electrodes and electrolytes,
But it wasn’t until 2010 that Naoi et al. proposed a real breakthrough by developing nanostructured composites of LTO (lithium titanium oxide) and carbon nanofibers.
