Commercialization of Samsung graphene batteries has been extremely difficult.

Samsung electronics announced yesterday that it had developed graphene battery technology. The battery capacity based on graphene material is 45% higher than batteries current market. Because it equipped with "graphene ball", it can be completely charged just 12 minutes. Due to the graphene battery can remain stable under the highest 60 degrees Celsius, new battery could be also used for electric cars.

Samsung advanced institute of technology (SAIT) said it was already put the study published in the journal nature communications, titled "the support fast charging, high volume energy density of rechargeable the lithium battery graphene ball ", and applied for a patent in South Korea and the United States.

The news immediately maxed circle of friends, but just look on coldly, not cheering.

Research firm KhashaGhaffarzadeh IDTechEx director said, Samsung has obtained some interesting results, but the distance commercial development of such batteries is still a long way to go. The battery technology is still in the proof of concept to the demonstration stage.

"This is a great potential use widely technique, but graphene battery needs a long time to go into mass production. "SK Kim young-woo securities (SKSecurities) said that "the key is who can beat to commercialize the technology. Application of fine processing technology for mass production of high quality electronic level graphene is not easy."

It is worth mentioning that in the country lithium electricity field of graphene battery news also often appear. According to incomplete statistics high lithium electricity, including east lumena electricity, tyrone, Buddha plastic science and technology, yoga wei stake, Shanshan stock, dow technology, chic, nunn power supply, such as Kant's new graphene in the field of lithium battery materials in the arrangement of the battery.

However, the so-called graphene batteries on the market, is only help the cladding material, graphene as a shop in the form of conductive agent added to the existing battery material, also prospects is unknown.

A capable of technical personnel said that from a technical perspective, the problem of graphene has two points: 1. The graphite layer of a layer of graphene after open, can be embedded lithium ion and embedded. But the surface area of graphene is bigger, under the current voltage of graphene embedded lithium, lithium ions and electrolyte on graphite surface produces chemical reaction, formation of SEI (that is, the solid liquid interface) membrane.

SEI film not only consumes the electrolyte, it will come out from the anode of metal lithium (battery efficiency is very low for the first time. Efficiency for the first time the amount of lithium ion charge back for the first time divided by the amount of lithium ion) for the first time. As the anode material was lithium ion batteries the most expensive in the material.

2. Even in the graphite when the preparation of the stratification, but it impossible to keep a layered state during application, roll up either, or several layers together, haven't really separated. If together, will not it originally to achieve results.

All in all, graphene is unlikely to do the cathode materials. Graphene may be used as conductive agent in the future. But note that, compared with other types of conductive agent, expensive graphene used as conductive agent when it remains to be seen whether better cost performance.
