Thanks to the efforts of scientists and engineers, EDLC is becoming more ideal every year. The main direction of development for them is an increase in specific power. In all likelihood, after some time, the ultracapacitor will become a complete replacement for batteries. These modules can replace batteries in a wide variety of technical areas.
Recent developments by scientists from the University of California have shown that the new type of EDLC almost doubles its best counterparts. We are talking about elements that are based on a porous structure. It uses graphene, on which ruthenium particles are deposited.
The pores of graphene foam have nanosizes that allow particles of transition metal oxides to be retained. Today these are the most promising ultracapacitors. They operate on an aqueous electrolyte, which ensures safe operation. Such elements are characterized by an increase in stored energy and a doubling of the allowable current strength in comparison with the best samples available on the market today.
The described ultracapacitor, the price of which, for obvious reasons, has not yet been announced, is capable of storing more energy per each cubic centimeter of its own volume. The downsizing makes it an advisable battery replacement. First of all, manufacturers of wearable and implantable electronics will want to buy such an EDLC. However, in the future we can count on the introduction of new products in the production of personal electric vehicles.
Elements based on graphene foam have already successfully passed the first tests. Tests have shown their ability to recharge more than 8000 times without a drop in performance.
