Despite the risk of explosion, lithium-ion batteries are potentially used to power almost all the electronic devices. To deal with such an issue, researchers reveal that they have refurbished the batteries fueled with nonflammable ingredients. Apart from wiping out the risk of explosion, the refurbished batteries are capable of storing more power as well.
According to a materials scientist, Gleb Yushin, “The future of electronic devices market and electric vehicles could possibly be secured, if the newly developed batteries are approved for commercial usage.
In the past few years, several types of research have been conducted, which include the substitution of organic electrolytes with solid or water-based electrolytes that can’t catch flames. In the case of water-based batteries, if the operating voltage exceeds 1.23 Volts, the water molecules in batteries split into hydrogen and oxygen gases that often lead to an explosion. However, this much voltage isn’t sufficient for batteries to store enough energy as compared to conventional lithium-ion batteries.
After several attempts, Wang and his team have come up with a water-in-salt electrolyte (WiSE) battery that is capable of storing energy at even 4 Volts and above. They used graphite-based cathode in the batteries. Apart from this, they also incorporated chloride and bromine in the electrode to shield water-based electrolyte by transforming reactive electrode materials into a stable form. Therefore, reactive lithium is converted into stable lithium-chloride and lithium-bromide salts.
On a similar note, EV industries appear distressed due to global scarcity of battery minerals. Tesla—a global leader in electric vehicles manufacturing—has appealed to the U.S. administration to raise investment in the mining sector. The EV maker wants to ensure the current availability of essential elements used in lithium-ion batteries’ production such as copper, nickel.
In the last few decades, very small investment has been reported in copper industries. However, the copper requirement by an electric car is almost double than an internal combustion engine.
