The Development Trend of Automotive Super Capacitor Technology in the Next Few Years



The development goal of automotive super capacitors is to continuously pursue higher energy and higher power products on the premise of maintaining long life, high safety and high reliability. Based on this goal, the current technology development trends mainly include the following aspects:



1. High performance and low cost carbon materials for super capacitors



Carbon materials are the core key raw materials for super capacitors. Whether it is an electric double layer capacitor, a lithium ion capacitor or an energy hybrid super capacitor, the activated carbon material with higher capacity, long life and low cost is an indispensable part. At present, there are two main raw materials for common activated carbon materials: coconut shell charcoal with conventional capacity and low cost and coke with high capacity and high cost. The development of high-capacity and low-cost activated carbon materials is a goal that the super capacitor industry has been pursuing.



2. Advanced electrode manufacturing technology for super capacitors



The core technology of super capacitors is the electrode manufacturing process. The high-performance electrode manufacturing process can bring about a great improvement in product performance.



3. Electrolyte technology with wide temperature and high voltage for super capacitors



super capacitor electrolyte with a working temperature of 85°C is in urgent need in the automotive field; improving the voltage withstand capability of super capacitors is the most direct way to increase the energy density of the product. Small-capacity super capacitors have been increased from the traditional 2.7V working voltage to 3V supercapacitor, but the large-capacity 3.0V super capacitors still have many problems; the development of high-performance electrolyte is imminent.



4. Better electrode compounding technology for super capacitors and optimization of positive and negative electrode ratios



For lithium ion ultracapacitor and energy hybrid super capacitors, the combination of electrodes and the optimization of the ratio of positive and negative electrodes means the improvement of energy density and the guarantee of long life. Research on electrode compound technology and optimization of positive and negative electrode ratios, and continuously improve the energy density of lithium ion capacitors and energy hybrid super capacitors, is the goal pursued by the car supercapacitor industry.

Supercapacitors for UPS

Image
The function of the super capacitor ups is often determined in the first few seconds to a few minutes after the power failure or the instantaneous collapse of the grid voltage. The battery needs to provide power during this period. The shortcomings of the battery itself need regular maintenance and short life, so that the UPS is running. It is necessary to always check the state of the battery. In a data protection backup system, the time required by the UPS is relatively short. The advantages of ultracapacitor ups are particularly pronounced, with output currents rising to hundreds of amps or even thousands of amps with almost no delay, and fast charging, energy storage in a short period of time, and 50,000 cycle life Do not need care for ten years, so that ups supercapacitor is truly maintenance-free. As one of supercapacitor manufacturers , we can offer kinds of super capacitor for sale, if you have needs, please contact us.
