us experts believe that lithium battery energy density increased by 2-3 times can be achieved
the day before, three of the world's top battery experts from argonne national laboratory and the northwestern university published a paper discusses the development process of chemical energy storage battery, and the development prospect of lithium battery is forecasted. they believe that in the future lithium battery energy density increased by 2-3 times is possible, but the key lies in the battery material innovation.
the three scientists are: argonne national laboratory director, senior scientist of electrochemical energy storage michael m. thackeray, argonne national laboratory, nano materials experts and physicist eric isaacs and northwestern university department of materials science professor christopher wolverton. their papers have been published in the seventh issue of the journal of the royal society of chemistry in 2012.
lithium batteries have been widely used in the digital field. however, due to the lack of power lithium battery, insufficient safety, and short cycle life, it has been unable to apply to the electric vehicle field and the large energy storage fields. in this regard, the experts pointed out in the paper, to promote lithium batteries in electric vehicles and intelligent networks required for the widespread use of energy storage systems, but also in the field of materials and chemical breakthroughs in innovation. they pointed out that the future lithium battery energy density increased by 2-3 times is possible, but need to find a better performance of the battery materials.
the paper concludes that a stable, volatile, and non liquid electrolyte should be developed to further improve battery safety. in addition, the paper points out that how to realize the stable operation of batteries under wide voltage range, as well as security and price, is a great challenge for the future research and development of lithium ion batteries.
