    Which is better, sodium battery or lithium battery? Why?

    2019-06-17 15:21:34 0

    The sodium-ion battery is now hot because everyone has estimated it and found that if a part of the car uses a lithium-ion battery, the lithium resources on the earth will be very tight. At that time, good lithium carbonate was sold at 180,000 / t, and the actual production cost was more than 20,000. Lithium is so expensive, then you need to develop new alternatives, sodium ion batteries. Therefore, the essence of sodium ion batteries is the supplement of lithium batteries. As a result, after research, we found that the price of lithium has dropped, and it has returned to the shape of 70,000. Some people think that sodium battery has a future. Some people think that electric vehicles will gradually develop, and sodium batteries still have hope. Some people have found that the energy density of sodium battery is 100Wh/kg higher than that of lead-acid battery 30Wh/kg. Since lead-acid batteries can be used on electric bicycles, how can sodium batteries fail? However, the cost of sodium batteries is not low, at most 20% lower than lithium batteries, but the energy density that can be used is also 40% lower, and the potential of sodium batteries is low, the cycle is not good, it is difficult to compete with lithium batteries.
