Eskarbon: porous carbon for batteries

Scientists around the world constantly thinking about how to strengthen the weakest point of the modern devices: their batteries. For example, electric developed sulfur batteries. A few days ago received a new message: Japanese firm Nippon Steel & Sumikin Chemical Co Ltd has developed a new material, called “eskarbon» («Escarbon»), including those intended for the batteries. In working on eskarbonom participated professor emeritus of molecular sciences (Institute for Molecular Science) Nobuyuki Nishi (Nobuyuki Nishi). Eskarbon represents a porous carbon, which has the ability to absorb the gas. Currently, there are real samples of the new Japanese material.

Eskarbonu preceded metal acetylide, combining acetylene carbon and metal atoms. Its structure provides the accuracy of its increments to nanometers (billionths of a meter). For this reason, he received the general name of “mesoporous carbon nanovetvyaschegosya» («mesoporous carbon nano dendrite», MCND).

MCND has branched tree-like structure with large pores, separated by sheets of graphene. The diameter of the mesopores is 2 to 50 nm and micropores less than two nanometers in diameter. Branching structure of this material provides an absorption of liquid gas.

It is assumed that MCND be used in the battery industry, as a catalyst support for a gas absorption. Software company is going to create samples of material intended for different tasks and organize its industrial production.

Devices requiring electrical power is getting bigger by the day. Humanity faces two major tasks: to learn to get from new sources and find a way to keep as much power for the devices in as a smaller battery. Today, even of sports can extract energy. Not to mention the solar energy that comes even to the most remote corners of the rapid civilization of the world.
