According to a paper its inventors published recently in Nature Communications, the Graz cell's performance exceeds that of a Li-ion battery. It is able, for example, to cope with up to 1m charge and discharge cycles, says Qamar Abbas, a member of the team. A Li-ion equivalent might be expected to manage a couple of thousand cycles.
根据其发明者最近发表在《自然通讯》上的一篇论文,格拉茨电池的性能超过了锂离子电池
Both Skeleton and the Graz group, then, are taking modified supercapacitor architecture and adding some bespoke electrochemistry. By contrast, although the offering from NAWATechnologies does indeed also employ modified supercapacitor plates as its electrodes, it uses tried and trusted Li-ion ingredients for the chemical donkey work.
于是,骨架和格拉茨团队都采用了改良的超级电容器结构,并添加了一些定制的电化学元素
Like Skeleton, NAWA already manufactures supercapacitors. The plates for these are created using a process which the firm calls VACNT(vertically aligned carbon nanotubes). This arranges those tubes in an array that resembles, in miniature, the bristles on a brush. Extreme miniature. A square centimetre contains about 100bn of them, all standing to attention. That greatly increases the surface area available to hold an electric charge.
NAWA和骨架一样,也在生产超级电容器
To adapt VACNT plates to operate also as battery-like electrodes, NAWA's engineers have thinned the nanotube forest to make room for coatings of the chemicals which batteries employ for their reactions, and also for the movement of lithium ions into and out of the spaces between the tubes. This freedom of movement, the company reckons, will boost the arrangement's power density by a factor of ten.
为了使VACNT板也能作为类似电池的电极使用,NAWA的工程师对纳米管进行了细化,为电池进行化学反应所使用的化学涂层腾出空间,为锂离子进出奈米管之间的空间腾出空间
To start with, the nanotubes of the invention's cathode (the positive electrode in a battery) will be coated with nickel, manganese and cobalt, a mixture already widely used to make such cathodes. Conventional anodes (the negative electrodes) are already carbon based, so using that element in the form of nanotubes is not a big departure. Other, less commercially developed battery chemistries should, though, also work with VACNT electrodes. These include lithium-sulphur and lithium-silicon, both of which have the potential to increase energy densities.
首先,该发明的阴极(电池中的正极)的纳米管将被镀上镍、锰和钴,一种已经广泛用于制造此类阴极的混合体
Silicon is particularly promising, but it swells as it absorbs ions, and that can rupture a battery. The thicket of nanotubes in a VACNT electrode should operate like a cage to keep the silicon in check, says Pascal Boulanger, a physicist who helped found NAWA in 2013. The new electrode material could also be used with solid rather than liquid electrolytes, to make "solid-state" batteries. These are powerful and robust, but are proving tricky to commercialise.
硅的前景极其光明,但它会在吸收离子的过程中膨胀,这可能会损坏电池
