Light lithium battery weight.best batteries for solar power storage

　　Light weight

　　It is larger than the energy, up to 150Wh/kg, which is twice the nickel -metalized battery and 4 times the lead -acid battery. Therefore, the weight is one -third to one -quarter of the lead -acid battery with the same energy. From this perspective There are few resources, and because the elements used in lithium manganate batteries are more reserves, compared to lead -acid and nickel -metal hydride batteries may further increase their prices, and the cost of lithium -ion power batteries is further reduced. The weight of the lithium ion battery for electric bicycles is 2.2-4 kg, the weight of the lead-acid battery is 12-20 kg, and the weight of the lithium battery is about one-quarter to one-third of the lead-acid battery. (36V, 10AH battery), the weight of the battery was reduced by 70%, and the total weight of the vehicle was at least 20%. In addition, the general lithium tram is a simple electric bicycle. Because the battery and the vehicle are light, the battery mileage of the same voltage and the same capacity is longer. The weight of the ordinary electric vehicle is more than 40 kg. Between 7 and 26 kg. Both ladies and the elderly can move easily, and the human ride is also very light, and both exercise and leisure. (3) The volume is small, up to 400Wh/L, and the volume is one -half to one -third of the lead -acid battery. Provides more reasonable structure, design conditions, design space and possibilities with more reasonable structure and more beautiful appearance. At this stage, due to the limitation of the volume and weight of the lead -acid battery, the design ideas of the designers have been greatly agreed. As a result, the electric bicycles at this stage are "thousand cars", similar and monotonous in terms of structure and appearance. The use of lithium -ion batteries provides designers with greater space and conditions to show design ideas and design styles. Of course, at the same time, it also leads to the diverse size of lithium -ion power batteries for electric bicycles, which is not conducive to the development of the lithium power battery industry. The lithium -power battery industry also needs to formulate national standards for electric bicycle lithium ion battery as soon as possible to accelerate the alternative of lithium battery batteries in the field of electric bicycles. Of course, in 2013, lithium batteries are very different from the volume of different materials and different process batteries in the continuous development process. How to unify is also a difficult point.
