Scientists around the world tirelessly think about how to strengthen the weakest point of modern devices: their batteries. For example, sulfur electric batteries are being developed for electric vehicles. The other day a new message arrived: the Japanese company Nippon Steel & Sumikin Chemical Co Ltd has developed a new material called “Escarbon”, which is also intended for batteries. An honorary professor at the Institute for Molecular Science, Nobuyuki Nishi, took part in the work on the escarbon. Escarbon is a porous carbon that has the ability to absorb gas. Real samples of this new Japanese material already exist.
Escarbon was preceded by metal acetylide, combining acetylene carbon and metal atoms. Its structure ensured the accuracy of determining its increment to nanometers (billionths of a meter). For this reason, he received the general name "mesoporous carbon nanobranch" ("mesoporous carbon nano dendrite", MCND).
MCND has a tree-like branching structure with large pores separated by graphene sheets. The diameter of these mesopores is from 2 to 50 nanometers, and micropores are less than two nanometers in diameter. The branching structure provides absorption of a given liquid gas material.
It is anticipated that MCND will be used in the manufacture of batteries, as a catalyst support and for gas absorption. The development company is going to create samples of the material designed for different tasks and organize its industrial production.
Devices requiring electrical power are becoming more and more every day. Humanity has two crucial tasks: to learn how to obtain it from new sources and to find a way to store as much power as possible for devices in the smallest possible battery size. Today, energy can be extracted even from sports. Not to mention the solar energy, which comes even to the corners of the world farthest from a fast-moving civilization.
