“Electric vehicle life doubled”, South Korean scientists said.
Battery technology change with each passing day, electric car driving distance is also improving! South Korean scientists released the latest electric car, each charge can travel 300 km away, the endurance is twice the general electric car, storage power is more than 4 times.
Gogangju Institute of Science and Technology (GIST) announced today that GIST Professor of Materials Science and Engineering, Professor Eom Gwang-sup and Postdoctoral Fellow, Institute of Electronic Research, Massachusetts Institute of Technology (MIT) Jung-tae work together to develop the latest lithium battery, if compared with the market’s products, the new lithium battery storage capacity of 4 times, battery life is also up to twice.
The traditional lithium battery is graphite, lithium metal oxide as the cathode and anode, because the two materials are low storage capacity to the current technology development, the storage capacity is near limit, so the electric Car battery storage capacity, the increase in space is not much.
Therefore, the South Korean research team decided to use the new material to produce battery anode and cathode, using silicon and sulfur. Scientists in particular to join the selenium to protect the silicon cathode, and then developed with lithium and silicon cathode, and sulfur and selenium production of the anode.
The newest lithium battery can store about 500 mAh of electricity per gram, compared with 100-150 mAh of electricity per gram of the battery on the market. This represents the electric car once every charge can run 300 kilometers, is the general electric car doubled.
Not only that, After 1000 charges and discharge, the battery capacity will only shrink by 19%. In other words, if the user once a day charging, can be stable for 4 years, no need to replace the battery; if the new lithium battery applied to the smart phone, then the weight of the phone can be reduced by half.
