The new batteries charge 10 times faster than lithium-ion batteries

Scientists at St. Petersburg State University in Russia have developed a new battery technology that not only allows batteries to charge up to 10 times faster than lithium-ion batteries, but also has little effect on battery capacity at low temperatures.

Oleg Levin, an electrochemical researcher at St. Petersburg State University, says the key to the new battery is a REDOX polymer based on nitrogen oxides, which in a series of experiments has been shown to charge batteries 10 times faster than lithium-ion batteries.

The REDOX polymer used is Ni-Salen (a combination of nickel and Salen), a metallic polymer that undergoes reversible oxidation (loss of electrons) and reduction (gain of electrons) during discharge and charge.

The researchers say that in experiments, the technology not only greatly accelerated the charging rate of the battery, but also worked well at low temperatures, with little effect.

However, the current drawback is that the battery's capacity is 30 to 40 percent lower than that of lithium-ion batteries. And scientists are now working to improve the battery's capacity even further.
