How about connecting three lithium batteries in series with a 40,000 microcapacitor?

Introduction After three lithium batteries are connected in series, the microcapacity of 40,000 is not good. Lithium batteries and capacitors have high energy storage capabilities if three lithium batteries are connected in series.

How about connecting three lithium batteries in series with a 40,000 microcapacitor?

After three lithium batteries are connected in series, the microcapacity of 40,000 microcapacitors is not good. Lithium batteries and capacitors have high energy storage capabilities. If three lithium batteries are connected in series and 40,000 microcapacitors are used, safety problems may occur, such as leakage, short circuit, overcharge, overdischarge, etc. pay attention to safety when using them.

How do voltage and capacity change when lithium batteries are connected in series?

When I was a child, I often called the capacitor on the printed circuit a "small battery". In fact, there really is a kind of capacitor that can when used as a battery, it is a supercapacitor.

Supercapacitors have the characteristics of Battery energy storage and charging and discharging characteristicshigh-speed discharge of capacitors. With such comprehensive performance, I think everyone will ask: why not use them in the car? In fact, supercapacitors have already penetrated the automotive industry, but practical problems still need to be solved. Today we will talk about the applications and prospects of supercapacitors in the automotive field.

30 seconds of charging as you go

Moscow's supercapacity buses can travel 20 kilometers on a single charge; Japan's supercapacity bikes can travel 20 kilometers after 20 seconds of charging; A supercapacitor light rail train has rolled off the assembly line in Zhuzhou, and can be fully charged within 30 seconds of stopping at a station. The design that can be used and charged takes advantage of the high-speed charging and discharging characteristics of supercapacitors. At the same time, theUltra-high number of cycles ensures battery reliability. But we noticed that the charging frequency of these cars is very high, because the energy density of supercapacitors is only one-fifth of that of ordinary batteries. At the same time, their cost is high, so it is necessary to use them alone as a source of energy. certain limits.

Durian cross-border supercapacitor

According to foreign media, Gomes from the University of Sydney recently published a paper mentioning the use of durian and jackfruit to create more efficient and effective supercapacitors. faster. capacitance. Gomes and his team said that by using the natural biological multi-space structure, this supercapacitor not only has the characteristics of multiple cycles and rapid charge and discharge, but also can significantly reduce production costs. At the same time, value-added reuse. biological waste is also part of environmental protection and sustainable development requirements. Either way, this “best of both worlds” research idea could open a new path in improving the performance and reducing the cost of supercapacitors.

Learning from each other's strengths, dual electric hybrid

As the world's largest supercapacitor company, Maxwell has cooperated with many automobile manufacturers. As of 2018, more than 6.1 million cars worldwide use this company's supercapacitors, and automakers like Cadillac, Geely, and Peugeot all use Maxwell's related technologies. In addition to participating in traditional hybrid system cooperation, Maxwell promotes the mixed use of lithium batteries and supercapacitors. Supercapacitors are used togetherent with batteries to achieve rapid response and extend battery life.

In 2019, Tesla acquired Maxwell and developed new batteries using dry electrode + supercapacitor methods to optimize its battery performance. On "Battery Day" on April 20 this year, Tesla will most likely announce two lithium battery and supercapacitor products. This is an important component of Tesla's new "hybrid" battery.

We are experiencing a revolution in the transition of automobiles from traditional energy sources to new energy sources. The commercial use of “supercapacitor + lithium battery” could be an important step in this revolution.

When this battery is connected in series, the voltage andcapacity changes.

1. Voltage increase: Multiple batteries are connected end to end, i.e. the negative of the first cell is connected to the positive of the second cell, and so on. . As the voltage increases, the capacitance remains unchanged.

2. Current remains unchanged: Current remains unchanged when connected in series. For example, the current of 700MAH lithium batteries is still 700MAH after being connected in series.

3. Capacity remains unchanged: Capacity remains unchanged when connected in series. For example, the capacity of a 1200 mAh lithium battery is still 1200 mAh after being connected in series.
