New breakthroughs in lithium batteries triple the battery life of electric vehicles

　　Battery technology is changing with each passing day, and the driving distance of electric vehicles is also improving day by day! South Korean scientists released the latest electric car, which can travel 300 kilometers per charge, has twice the endurance of ordinary electric cars, and has 4 times the stored power.

　　Battery technology is changing with each passing day, and the driving distance of electric vehicles is also improving day by day! South Korean scientists released the latest electric car, which can travel 300 kilometers per charge, has twice the endurance of ordinary electric cars, and has 4 times the stored power.

　　Traditional lithium batteries use graphite and lithium metal oxide (LithiumMetalOxide) as cathodes and anodes. Because these two materials have low power storage, after the development of current technology, the power storage is close to the limit, so the electric vehicle The storage capacity of the battery does not add much space.

　　Therefore, the Korean research team decided to use a completely new material to make the cathode and anode of the battery, using silicon and sulfur. Scientists specially added selenium to protect the silicon cathode, and then developed a cathode with lithium and silicon, and also made the anode with sulfur and selenium.

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

　　Not only that, the new lithium battery will only shrink by 19% after 1,500 cycles of charging and discharging. In other words, if the user recharges it once a day, it can be used stably for 4 years without changing the battery; if the new lithium battery is applied to a smart phone, the weight of the phone can be reduced by half.
