Several kinds of lithium battery electric bicycle have? What's the best?
Three yuan in the price, the more neutral material battery safety, life and other aspects of the production process, but also (voltage * capacity) of different specifications of the battery, the battery weight of three yuan materials with volume is far less than other types of batteries, lithium battery personally think that the most appropriate at this stage should be three yuan battery materials.From the core structure types, there are cylindrical batteries, steel shells, square batteries, soft packaging (polymer) batteries, etc., mainly these kinds of electric core combination. Square steel shell with the more, there are many soft cylindrical, also the development of good, it is the trend for the pros and cons; do not criticize, prefer the soft package (polymer) batteries.
Lithium batteries are lighter, but they are very problematic. I bought a lithium battery at a website last May. It was pretty good at the beginning. A trip of 30 kilometers still makes up 80% of the power, because it's more precious, so I'm using it as soon as possible to keep it full. But about half a year, power began to decay a lot, and now full of electricity, only 30 kilometers a year, than the lead-acid battery is still poor! And I bought the domestic big brand lithium battery, that what WEI, here do not let hair name, can't be fake! Lithium battery and lithium iron phosphate batteries now speculation, single cycle may be reached hundreds of thousands of times, but the combination is hard to say, as long as there is a battery of a problem, the battery will be affected, and I think China should no manufacturer can guarantee the stability of lithium battery, so after a half year appear large amounts of electricity attenuation situation. Personally feel that there is no need, it is best not to buy lithium batteries, especially in the Internet to buy lithium batteries, the problem of tossing and dying.
According to the cathode material system, the material of three yuan material, lithium iron phosphate and lithium manganate material is usually used;Comprehensive performance comparison:Three kinds of materials, battery safety can be, lithium iron phosphate, lithium manganese dioxide safety is better;Lithium manganese oxide battery life is the worst compared to the other two, but also the cheapest;Lithium iron phosphate is currently the fire, but speaking is not very mature; lithium iron phosphate life is good, but its low temperature performance is poor, in colder areas, can release the power ratio is less, small capacity;
There are 3 kinds of lithium batteries: three yuan material, polymer portable lithium battery, lithium manganate lithium battery, lithium iron phosphate battery. XDS is three yuan for polymer lithium battery.
