Scientists improve the battery better

Russian chemists together with their Singapore and Israeli colleagues have created new materials to produce anode for sodium-ion batteries. In the future, cheap and abundant sodium may replace lithium in mass-produced batteries. This invention is also useful in the automotive and electronics industries for laptop and smartphone manufacturing.

Scientists have sought to improve lithium-ion batteries used in electronic devices. The main problem is that the world's lithium reserves are very limited, and costly. Scientists from Moscow's Institute of Basic Chemistry and Inorganic Chemistry, together with experts from Singapore and Israel, have found a solution. They have developed anode-anode for sodium-ion batteries. Scientists make thin films of antimony sulphide , which is the basis of the anode.

It is predicted that the sodium battery would be much cheaper than the lithium battery. Because there are more sodium on the Earth, the same metal with lithium. For example, sodium chloride (salt) is one of the most common chemical compounds.

Previously, it was not possible to manufacture sodium batteries because the sodium ions were not dipped in conventional graphite electrodes. Thanks to antimony sulphide, this problem is currently being solved. Researchers say the technology is non-toxic, low cost and does not require particularly sophisticated equipment.

New technology has a great future because sodium can be extracted from table salt. It is no coincidence that the development of sodium-ion batteries has also been conducted in other countries, such as Tokyo University of Science, Japan.
