New Delhi: A big claim has come to light in the field of battery technology. Chinese scientists have claimed to have developed a new sodium metal battery which can be fully charged in just four minutes. The researcher says that this battery is capable of maintaining its capacity for a long time with fast charging. However, this technology is still in the initial research stage and it may take time to reach common consumers.

Which batteries are used in smartphones

Today, lithium-ion batteries are mainly used in smartphones, laptops and electric vehicles around the world. But due to limited availability of lithium and rising prices, scientists have been searching for its cheaper and safer alternative for a long time. In this direction, sodium based battery is being considered as a technology with future potential.

Sodium will be used instead of lithium

According to new research, sodium has been used in place of lithium in this battery, which will be easily available and also of relatively low cost. Scientists have developed a special quasi-solid gel electrolyte for this, which prevents dendrites from forming within the battery. Dendrites are sharp metal particles, which can cause short circuits and battery damage.

will charge faster

Researchers claim that with the help of this technology the battery not only charges faster but also remains safer. In lab tests, this battery continued to work successfully for thousands of hours without any short circuit. And even after about 2,000 charging cycles, about 90 percent of its capacity remained intact.

However, experts say that at present this technology is not ready to replace lithium-ion batteries. Its energy density is still lower than traditional lithium batteries, so it may take time to start using it in smartphones and long distance electric vehicles.

When will these batteries come in the market

At present this technology is limited to research laboratories. Scientists believe that it can be launched in the market only after large-scale production, testing in different climates and meeting safety standards. If further tests are successful, this technology could bring a big change in electric vehicles, energy storage systems and many other areas in the coming years.
