The rise of mobile devices has indirectly promoted battery technology research, but every so-called "breakthrough" seems to be out of reach. The latest development is that the California Institute of Nanotechnology under the University of California, Los Angeles (UCLA) has created a new energy storage medium that integrates the best quality of both supercapacitors and batteries with two types of nanoparticles. "hybrid super capacitor." Phys.org pointed out that an ultracapacitor is an electrochemical component that can be charged in a matter of seconds (a few hours for ordinary batteries), and its charge and discharge cycles are around one million times. Unfortunately, it is difficult for both fish and bear's paw to have both, although the charging speed is happy, but the super capacitor can store a relatively limited amount of energy, and it is difficult to meet the current needs of mobile devices. The good news is that the research team of the California Institute of Nanotechnology has proposed a more compromised hybrid solution. In addition to being able to quickly charge more than 10,000 times, its thickness is only 1/5 of a piece of paper, enough to tuck in. Wearables or even implantable devices. Integrating manganese dioxide and graphene (the former is also a common raw material for alkaline batteries) through laser- scribed technology, this hybrid ultracapacitor achieves a good balance between low cost, high speed, and number of recharges. . Impressively, the number of charging times even exceeds twice that of a typical thin-film lithium battery. Richard Kaner, a professor of chemistry and biochemistry who led the research, said that this hybrid supercapacitor has great application prospects in real life and is expected to greatly enhance the experience of personal electronic devices in the future.
Auxiliary Agent For Alloying /Calcium Carbide
This is used for making Calcium Carbide and smelting as an agent. It is not the raw material, but it is an important agent during production.
