lithium 3400mah 3.7v 18650 battery

　　New breakthrough in lithium 3400mah 3.7v 18650 battery that can double electric vehicle range

　　Battery technology is advancing with each passing day, and the driving distance of electric vehicles is also improving day by day! Korean scientists have released the latest electric vehicle, which can travel 300 kilometers per charge, has twice the endurance of ordinary electric vehicles, and stores four times as much electricity.

　　Traditional lithium 3400mah 3.7v 18650 battery use graphite and lithium metal oxide (Lithium Metal Oxide) as cathodes and anodes. Since the power storage of these two materials is low, after the development of current technology, the power storage is close to the limit. Therefore, the power storage of electric vehicles There is not much room to increase the battery storage capacity.

　　Therefore, the Korean research team decided to use new materials to make battery cathodes and anodes, using silicon and sulfur. Scientists specially added selenium to protect the silicon cathode, and then developed a cathode with lithium and silicon. In addition, they used sulfur and selenium to make anodes.

　　The latest lithium 3400mah 3.7v 18650 battery can store about 500mAh of electricity per gram, compared to batteries on the market that can only store 100-150mAh of electricity per gram. This means that an electric vehicle can travel 300 kilometers per charge, which is twice as far as ordinary electric vehicles.

　　Not only that, after the new lithium battery is charged and discharged 1,500 times, the battery capacity will only shrink by 19%. In other words, if the user charges it once a day, it can be used stably for 4 years without replacing the battery; if the new lithium battery is applied to a smartphone, the weight of the phone can be reduced by half.
