Polymer batteries and lithium-ion batteries are better than polymer batteries. The fundamental difference between the two is the difference in raw materials.
Polymer battery refers to the use of polymer material in at least one of the three components of the positive electrode, negative electrode or electrolyte. High polymer means large molecular weight, and its corresponding concept is small molecule, high polymer has high strength, high toughness and high elasticity. At present, the research and development of polymer battery polymer materials are mainly used for positive electrode and electrolyte. Lithium batteries use electrolyte (liquid or colloid), electrolyte is the chemical battery, electrolytic capacitors used in the medium (have a certain corrosive), for their normal work to provide ions. And make sure that the chemical reactions that take place on the job are reversible.
Polymer cells can be thin, arbitrary area and arbitrary shape because the electrolyte can be solid or colloidal rather than liquid. The current polymer is mostly soft pack battery, using aluminum plastic film as the shell, when the internal use of organic electrolyte, even if the liquid is very hot also do not explode, because the aluminum plastic film polymer battery is solid or colloids without leakage, just natural rupture. Because the polymer battery is made of polymer material, it can be made into a multi-layer combination in the cell to reach high voltage, while the nominal capacity of the lithium battery cell is 3.6V. In order to achieve high voltage in practical use, it is necessary to connect multiple cells in series to form an ideal high-voltage working platform.
The above several characteristics compare the polymer battery and lithium battery which is good, then it must be better polymer battery.
13 electric vehicle lithium battery and battery which good
Electric vehicle battery is relatively monotonous, the general electric vehicle battery is lead-acid battery, a small number of relatively small electric vehicle is lithium battery. Lead-acid batteries are much more widely used than lithium-ion batteries, so if you're going to choose a battery for the masses, it's the battery. Lead acid battery is cheaper, that is to say, the cost performance is relatively high, and its quality is also better, not cheap quality is poor, in general, buy lead acid storage is more cost-effective. Moreover, in terms of the use effect, it is not bad, explosion-proof configuration of what are better.
If you want to consider how far it can run, it is certainly not better than lithium battery, but for the average family, it runs enough distance, so use this battery is a very wise choice. Lithium battery is also used in some electric vehicles. The cost of this type of battery is really high. A better type of battery costs 1000 or even 2000, so many people do not choose to use it because of the price. It is also of much better quality than lead-acid batteries.
It is lighter in weight, which means that electric vehicles can run longer and last longer. But the disadvantage of lithium batteries is that they are relatively easy to explode. There are many people who use batteries, and there have been explosions, especially when the weather is hot, and they are more prone to explosion. Try not to use them in the summer. In general, lead-acid batteries than lithium batteries to use a little bit of insurance, but also more use, most people choose to use lead-acid batteries, he must have the reason to use. Of course, lithium-ion batteries are also relatively good, and they do work better than lead acid batteries.
