Graphene is expected to trigger a new breakthrough of super battery
[news] is super battery cable, stable performance, reasonable price is the human dream over the years. At present, describe the image of the people on the super battery is a rechargeable electric vehicles, can travel 1000 kilometers, so that the smart phone for a week, the charging time can be controlled within a few minutes, the best wireless charging. This super battery market scale of not less than $1. At present, the United States, China, Japan and South Korea are all in the sprint super battery.
At present, lithium ion batteries used in 1991 began commercial, mainly cobalt acid lithium iron phosphate and lithium manganate 3 types. But from the super battery requirements, there is a large gap between the. Graphene is expected to lead to new breakthroughs in battery manufacturing, a new system based on graphene battery performance is subversive, called “ super battery ”. The use of this material battery energy density is more than 600wh/kg, 5 times the current power lithium battery, just 8 minutes on a single charge, can travel 1000 kilometers.
The application of graphene technology is still in the primary stage, especially the graphene material can make the battery size and weight is greatly reduced, the low rate of finished products, high production costs, has become an important cause of graphene battery to industrialization. Therefore, further innovation, improve technology, reduce the production cost, is the key to the future development of graphene battery. At present, China led the world in graphene research and application, there are a variety of battery graphene and graphene lithium sulfur battery has made breakthrough progress.
Process for super battery, is the process of technological innovation, process and industrial structure optimization. Super battery with graphene as the representative of the day will be to achieve a breakthrough, including electric cars, mobile phones, computers and other devices all rely on the power of change, will be subversive significance for a number of industries, will open a new page of human life.
