Polymer cathode for sodium battery designs
An American-Chinese team of scientists has developed a high-performance cathode made of an organic polymer for the next generation sodium battery technology.

The PHATN cathode was then tested in metal ion batteries with a highly concentrated electrolyte. The tests showed excellent battery data. The sodium ion battery could be operated at a voltage of 3.5 volts and, according to the data, even after 50,000 charge-discharge cycles, still had a proud capacity of over 100 milliamperes per gram. The magnesium ion battery and the aluminum ion battery were only slightly worse.

Such advanced pyrazine polymer cathodes (pyrazine is the basic substance of HATN, it is an aromatic benzene-like but nitrogen-rich organic substance with a fruity fragrance) could be used in next-generation environmentally friendly, long-lasting, rechargeable high-performance sodium battery designs, the scientists assume.
