What are supercapacitors?
Can supercapacitors replace batteries?
We get a lot of questions about using supercapacitors instead of batteries in passenger cars or other applications, but unfortunately, it’s not that simple. Yes, supercapacitors have many advantages over batteries such as a significantly longer lifetime, much higher reliability and durability, and high efficiency even in -40°C, but the problem is that batteries and supercapacitors are used for different purposes.
If you need energy for a long time, batteries are usually the most economical solution. For short-term applications, supercapacitors are often the best option. Defining “short-term” is not that simple, however, but as a rule of thumb, you should consider supercapacitors if the application time is 30-45 seconds, usually much less. Our 2nd generation graphene supercapacitors can extend the application time significantly, and the upcoming SuperBattery technology increases even further, competing with high-power batteries.
