Graphene, as a new material, is very expensive, but Yadea has mastered the technology, so it can be mass-produced, and Yadea has also made it a reality for graphene to be widely used in the modification of lead-acid batteries. This kind of graphene battery has the stability of long-term use and has made great progress compared with ordinary lead-acid batteries.
Extended data:
Graphene principle: The circuit made in the experiment contains LED, which is connected to the ribbon graphene with wires. They just put graphene in copper chloride solution to observe. The LED light is on. In fact, they need six graphene circuits in series to generate the required 2V and make the LED light emit light to get this picture.
