What batteries are used in general electric vehicle batteries, or are lead-acid batteries good or lithium batteries?
The electrode of lead acid battery is mainly made of lead and its oxide, and the electrolyte is sulfuric acid solution. Under the charge state of lead acid battery, the main component of positive electrode is two lead oxide, the main component of negative electrode is lead, and the main component of positive and negative electrode is lead sulfate.The four and two batteries are all energy storage devices, but others are different. The lead-acid battery is safer, cheaper, but lower energy density than battery, so it is large volume of lead-acid battery. At this stage, the battery (storage) technology research is still unable to obtain a breakthrough, namely "low cost, high performance battery has not been put into commercial application before, can be excellent characteristics of lead-acid batteries and lithium batteries of the existing combination of transformation and upgrading, as the main research topic at present and future period in. Believe that this will be the future of the elderly electric scooter, and even the entire electric scooter industry has a clearer direction.
Lead-acid batteries and lithium batteries can not be simply good or bad terms, the two have their own advantages and disadvantages, adapted to different needs of the crowd. Currently on the market for "electric bicycle lithium products" and onward not far away cars, but like four wheel electric vehicle, four wheel electric scooter which is far from old onward the current situation is quite suitable for the lead-acid battery".Two, the lithium ion mainly depends on the lithium ion to move between the positive pole and the negative electrode. During the charging and discharging process, the Li+ is inserted between two electrodes and inserted and removed. When the charging cell is used, the Li+ is removed from the positive electrode, embedded in the negative electrode by electrolyte, and the negative electrode is in a lithium rich state. The discharge is reversed. Generally use lithium containing materials as electrodes of the battery, at this stage the negative pole is graphite. Compared to lithium batteries and lead-acid batteries, lithium battery has the advantages of light weight, high capacity, long cycle life and so on, it is the elderly electric scooter vehicle power supply, not only lightweight portable charging, but also help the vehicle product lightweight and simple design.
At present, the market for electric vehicles, lead-acid batteries storage capacity is still higher than that of lithium batteries, the reason is that the current cost of lithium batteries is still relatively high. Therefore, in the design of the existing "lithium tram" products, the capacity allocation of reducing lithium batteries is mostly adopted to reduce the implementation cost of the whole vehicle, which makes the existing models of "lithium tram" products too simplistic.
