New battery materials available, mobile equipment life or will increase 10 times – Sohu Technology

Launch a new battery materials, battery or mobile devices will increase 10 times – Sohu science and technology for the mobile electronic device, when the life length is too short is still a problem to be solved, the battery capacity often become some electronic products selling point. Recently, Northwestern University researchers have discovered a new material called COF (covalent organic framework), which is likely to break the status quo of lithium battery led mobile devices. The team led by William Dichtel is currently working on COF, and they have done a lot of upfront investment. "COF (covalent organic framework)" is a crystal structure, this structure is precisely composed of suitable for the storage of electrical energy pores, conductive material to help fill. The study found that the new material can withstand tens of thousands of times of charge and discharge cycles, the overall capacity of 10 times the traditional material, while the maximum recharge rate can be increased by up to 15 times. In addition to Northwestern University, Samsung, apple, Tesla and other commercial enterprises are also trying to improve their battery products, trying to improve their storage capacity while lightweight. 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.

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.
