New battery material available, mobile device life or will increase 10 times

For mobile electronic equipment, long life is still a problem to be solved, the battery capacity has often become a selling point of some electronic products. Recently, researchers at the Northwestern University found a new material called COF (covalent organic framework), which will be likely to break the current status of lithium batteries for mobile devices.

Dichtel William led the team is currently working on COF research, they have also carried out a considerable upfront investment. "COF (covalent organic framework)" is a crystal structure, which is composed of pores suitable for storage of electrical energy, which can be used to fill the conductive material. The study found that the new material can withstand the tens of thousands of charge and discharge cycle, its overall capacity reached 10 times the traditional materials, and the rate of return can be up to 15 times.

In addition to the Northwestern University, Samsung, apple, Tesla and other commercial enterprises are also trying to improve their own battery products, trying to improve their storage capacity at the same time in light. A company called Amprius battery company even in battery technology by the use of nanotechnology, the use of silicon and sulfur electrode to create very complex structures, thus ensuring that the battery can surpass the standard products in the capacity and rate.

However, there are many areas need to bypass the battery R & D pit, too "lead" is likely to collapse some projects. SONY can serve as a lesson for us, although they realized the commercialization of lithium ion batteries successfully in 1991, but due to low performance and technical bottlenecks, finally can only transfer the business to the battery murata.

Although William Dichtel is full of confidence for the new COF, it can be effectively applied in the industrial field, but the Northwestern University has not developed a battery prototype, from civil popularity there is still a long way to go. These new battery products including COF, more or less are faced with the problem of high cost and slow development, from the beginning of the research and development of lithium battery to the actual commercial middle spans nearly 1 centuries, the new battery material road doesn't seem so clear.
