Super capacitor
upercapacitors may be the next-generation battery technology that is most promising. First, it can store energy in an electric field, not in a chemical reactant, which means it can withstand more charge and discharge cycles.

At present, many technology companies are developing supercapacitors, such as Skeleton Technologies. Their products use coupling technology to mix supercapacitors, enabling batteries to have high energy density, high power, and output characteristics. They can be filled in as little as 2-3 seconds. Electricity, and provide about 1 million charge and discharge cycles, the battery capacity is 50% higher than the current lithium battery.

The power of the environment
There are many ways to obtain electrical energy. It can even transform the elements of the surrounding environment into energy. For example, sound, a technology that can convert sound into electricity through nanogenerators, provides continuous power for mobile phones; MIT scientists have discovered a way to absorb dew from the air and convert it into electricity. This world is very wonderful, and as the scientists continue to deepen, perhaps many of the elements that we are indifferent to can provide energy.
