Lithium-ion batteries is an ideal commercial energy storage technology that people can find today, but they are still not flawless, especially in terms of security. Therefore, efforts to find alternative technologies for lithium-ion batteries have not stopped. Super capacitors can be regarded as a strong candidate.
Compared with traditional capacitors, the structure of supercapacitors is special. It can be simply understood as two porous electrode plates added to the electrolyte. When the electrode plates are electrified, the ions of opposite polarity in the electrolyte will form two capacitive storage layers nearby the electrodes to achieve the purpose of energy storage.
The size of the energy storage capacity of a super capacitor is positively related to the surface area of the electrode. Since the surface of the super capacitor electrode is mostly porous carbon material, the effective area is large (up to 2000 m2/g), and the ability to store energy (electrostatic capacity) is much larger than traditional capacitors and has a small charge separation distance, which is also the meaning of the word "super". Such a special architecture also determines that supercapacitors have many advantages compared with other energy storage technologies, such as:
①The capacitance is far beyond the traditional capacitor, the range can reach 0.1F~1000F, and tens of thousands of F.
② Very fast charging speed, usually charging for 10 seconds to 10 minutes can reach more than 95% of its rated capacity.
③Long cycle life, the number of charge and discharge cycles can reach 500,000 times, and there is no "memory effect".
④The power density is high, up to 300W/KG~5000W/KG, which is equivalent to 5~10 times of the battery.
⑤The high current discharge capacity is strong, and the energy conversion efficiency is high.
⑥Reliable guarantee; simple charging and discharging circuit, no special protection circuit is needed.
⑦Good low temperature characteristics, wide temperature range of -40℃～+70℃.
⑧Environmental protection, the product raw material composition, production, use, storage and dismantling process are all pollution-free.
This is why nowadays supercapacitors are used in new energy vehicles. To purchase supercapacitors, you must choose a reliable manufacturer. Dongguan Zhixu Electronic Co., Ltd.
