Supercapacitors are going beyond batteries, providing advantages of safety, fast charging and size, and at the same time, providing help to eliminate complex battery management systems in automotive, grid, and IT applications.
Perhaps in the near future, supercapacitors will eventually "replace" the current lithium-ion battery technology. In the next 20 years, more and more supercapacitors will be used in various industries. China is the market with the most potential for development of supercapacitors. In the future, the improved supercapacitors and their variants are microgrids, trains, trams, trucks, heavy off-road vehicles, taking advantages of energy collection to provide tiny uninterrupted power supply for IoT nodes, and provide huge opportunities for giant power supply of 1 MW/hour for hospitals and data centers.
The potential advantages of supercapacitor technology are as follows: "You can charge them quickly because the only step is to put the current in. Supercapacitors can also be located between the charging station and the grid. You also have to deliver a lot of current. So, there is a spare supercapacitor equipped with extra power. It’s time to install it in the car when the car is there, which is also possible.”With the continuous growth of transportation, Internet of Things and data center applications, supercapacitor technology will be developed rapidly.
Without electricity, nothing can be done. Fast-charging electric vehicles will surely be a major selling point. Supercapacitor technology bears great hopes. In a case, industry analysts envision urban light rail and bus networks to charge batteries in 20 seconds while reducing the need to replace expensive batteries. The recycling of expensive materials will also be eliminated.
It seems that supercapacitors have replaced 10% of expensive lithium-ion batteries and will soon replace lead-acid batteries. The improvement and market promotion of supercapacitors are proceeding rapidly, and significant progress and innovation will occur in the next 20 years.
