Lithium batteries are twice as powerful as conventional electric cars.

Battery technology is changing day by day, electric vehicle driving distance is also improving day by day! South Korean scientists have unveiled the latest electric vehicles, which can travel 300 kilometers per charge, have twice the endurance of a typical electric car, and store up to four times as much electricity.

Battery technology is changing day by day, electric vehicle driving distance is also improving day by day! South Korean scientists have unveiled the latest electric vehicles, which can travel 300 kilometers per charge, have twice the endurance of a typical electric car, and store up to four times as much electricity.

State Institute of Science and Technology(GIST) announced on the 10th that Eom Gwang-sup, a professor of materials science and engineering at GIST, and Lee Jung-tae, a postdoctoral researcher at MIT's Electronic Research Laboratory, have teamed up to develop the latest lithium batteries, if they are compared to products on the market The new lithium-ion battery will store up to four times its power and will have twice as much battery life.

The traditional lithium battery uses graphite, LithiumMetalOxide as the cathode and anode. Since the storage power of these two materials is low, after the current technological development, the storage power has reached the limit, so the battery storage capacity of electric vehicles., There is not much room for increase.

Therefore, the Korean research team decided to use a new material to make the battery anode, using silicon and sulfur. Scientists specifically added selenium to protect the cathode made of Silicon, and then developed a cathode containing lithium and helium, and made anodes with sulfur and selenium.

The latest lithium battery can store about 500 mAh of electricity per gram, compared to only 100-150 mAh of electricity per gram of batteries on the market. This means that an electric car can run 300 kilometers per charge, which is twice as much as an electric car.

Not only that, the new lithium battery will shrink its battery capacity by only 19 inches after filling and discharging 1,500 times. In other words, if the user charges once a day, he can use it stably for 4 years without replacing the battery; If the new lithium-ion battery is applied to a smartphone, the weight of the phone can be reduced by half.
