Nowadays, lithium batteries are widely used whether in electronic products or in the field of new energy vehicles. Of course, it also has certain drawbacks, for example, the capacity is affected at low temperatures.
According to foreign media reports, the science and development of St Petersburg State University in Russia has developed a new type of battery technology, which not only makes the battery charge 10 times faster than that of lithium batteries, but also has almost no effect on battery capacity at low temperatures.
Oleg Levin, an electrochemical researcher at St. Petersburg State University, said that the key to the new battery is a redox polymer based on nitroxide radicals. A series of experiments have shown that the battery using the new polymer can charge 10 times faster than lithium batteries. .
The redox polymer used is Ni-Salen (synthetic form of nickel and Salen), which is a metal polymer. This material can undergo reversible oxidation (loss of electrons) and reduction (gain of electrons) during discharge and charging. ).
In this case, the redox polymer used is a synthetic form of Ni-Salen (nickel salen). NiSalen is a metal-containing metal polymer in which nickel and salen atomic chains act as molecular wires to improve electronic conductivity , This is the limitation of nitro-based polymer batteries.
The researchers said that through experiments, the battery using this technology not only greatly speeds up the charging speed, but also worksextremely well in low-temperature environments, with little impact.
it also has advantages in terms of cost and environment, because the nickel used in this technology is much lower than that used in lithium batteries. And compared with lithium batteries, safety is also more guaranteed.
However, this battery currently has its drawbacks. Compared with lithium batteries,
its capacity is 30% to 40% lower. And scientists are now also working hard to further improve the battery capacity problem.
