Lead acid battery or lithium battery electric vehicle, you?

Source: 2020 - 04 - 01 hold hits: time for electric cars, which do you prefer lead-acid battery or lithium battery? We can see every day on the road, the electric force coming and going. To and from work, school, shopping, electric vehicle plays an indispensable role in the travel. As is known to all, the main impetus for electric cars from the battery, battery has two types: lead-acid battery and lithium ion batteries. Today, let's talk about the advantages and disadvantages of them! Low lead-acid battery lead-acid battery ( VRLA) Is a composed of lead and its oxide electrodes, battery is a sulfuric acid solution. Under the condition of lead-acid battery discharge, the positive principal component as the lead dioxide, negative principal component for the lead. Under the condition of charging, the positive and negative lead sulfate is the main ingredient. Low lithium battery lithium battery is a lithium metal or lithium metal and used a battery nonaqueous electrolyte solution. Lithium battery can be roughly divided into two kinds: metallic lithium battery and lithium ion batteries. Metallic lithium batteries was firstly presented and research by GilbertN. Lewis in 1912. Due to the lithium distinctive chemical properties, processing, preservation and application of lithium metal has high environmental requirements. As a result, the lithium battery haven't in use. With the development of science and technology, the lithium battery has become the mainstream. / / the advantages and disadvantages of lead-acid battery hobbies: cheap, recycled, after with old change new, after the price difference can change a new battery, minimize loss. 'fight' ability is strong, even broken a little repair can continue to use. Defect: lead-acid battery and composition are big size, composition in 16 - commonly 30 kg, under normal circumstances, the depth of charging and discharging within 400 times, have recalled, in 2 years service life. Lead-acid batteries contain liquid, when the battery burning after a period of time, if it is found that the battery overheat or charging time is too short, just need to compensate for liquid. / / lithium battery hobby: the advantages and disadvantages of small volume, light weight. Compared with lead-acid batteries, lithium batteries for lead-acid battery two-thirds of the volume, volume weight of about a third of the lead-acid battery weight. Lithium ion batteries are the same size is bigger than lead-acid battery capacity, battery after weight range increased by 10%. In terms of charging and discharging lithium batteries more durable than lead-acid batteries. Under normal temperature, lithium battery can charge 48 hours in a row, will not result in cell expansion, leakage, fracture. Production capacity in more than 95%. And under the special charger, can fast charge and discharge. Deep deep put more than 500 times, has not been recalled, generally is about 4 - life For five years. Defect: lithium battery manufacturing cost is high, the manufacturing equipment is expensive, labor costs accounted for about 40% of the manufacturing costs, the price is about three times that of lead-acid batteries. Lithium battery recycling value is not high, generally finished with lithium battery can only be thrown away, cannot be recycled. Now with the new national standard of be born, lithium battery electric bicycle is more and more dominant. To a small survey, your electric car is lead acid battery or lithium battery?
