Types of lithium batteries
(1) Lithium batteries can be divided into liquid lithium batteries according to the different electrolyte materials used in lithium batteries.(ion battery, abbreviated as LIB) and lithium polymer (lithium polymer ion battery, abbreviated as LIP).The positive and negative materials used in lithium polymer are the same as liquid lithium, and the working principle of the battery is the samebasically the same. The main difference between them is the electrolyte. Lithium batteries use a liquid electrolyte, whileLithium polymer is replaced by a solid polymer electrolyte, which can be "dry" orIt is "colloidal". Most polymer colloidal electrolytes are currently used.

Liquid lithium batteries are not used as a focus due to application environmental restrictions and other reasons, today we will distinguish between the focus on the use of 18650 lithium batteries and lithium polymer batteries
Second, the advantages and disadvantages.
1, lithium polymer batteries
Advantages: the working voltage of the single cell is up to 3.6v~3.8v much higher than the 1.2V voltage of NiMH and NiCd batteries. High capacity density, its capacity density is 1.5 to 2.5 times that of NiMH or NiCd batteries, or higher. The self-discharge is small, and the capacity loss is small even after a long time. No memory effect, no need to empty the remaining power before charging, easy to use.
Disadvantages: High cost of battery, difficult to purify electrolyte system. Need to protect the line control, overcharge or overdischarge will make the reversibility of the internal chemical substances of the battery is destroyed, thus seriously affecting the life of the battery.
2、18650 lithium battery
Advantages: the capacity is generally between 1200 mAh to 3600 mAh, and the general battery capacity is only about 800 mAh, if combined into 18650 lithium battery pack, that 18650 lithium battery pack is casually can break through the 5000 mAh.
Disadvantages: The main disadvantage of 18650 lithium battery is that his volume has been fixed, installed in some notebooks or some products are not very good positioning.
With the rapid changes in the market of electronic products, electronic waste is an important component of lithium batteries, the face of such a huge challenge, we can not take certain measures to deal with the decomposition of it?
With the problem we first to understand the current domestic lithium battery separation and recycling equipment mainly using physical recycling methods, disposal measures in line with the principle of green low-carbon, energy saving and environmental protection, no secondary pollution, and take into account the economic and environmental benefits brought about by the impact to think about this issue. China environmental protection online column gives us the answer "there is no garbage in the world, only misplaced resources". Waste to treasure will become a major trend, boosting economic development to speed up the change
Our company produces waste lithium battery crushing and recycling equipment in line with the manufacturing concept of energy saving and environmental protection is a good solution to this problem, so that the challenge into an opportunity, lithium batteries inside the mercury, carbon, lead, iron, zinc, manganese, cadmium and nickel and lithium battery packaging copper, aluminum, iron and other common metals, including graphite powder and lithium cobaltate powder is an important part of the treatment, these materials also have a high economic utilization rate in the market. The waste lithium battery crushing and recycling equipment lithium battery and recycling not only realize the green environment, the use of components can also harmlessly deal with harmful components. The whole recycling process has achieved industrial automation, high recycling efficiency and strong reprocessing capacity, so that the waste lithium battery crushing and separation, processing valuable components recovery rate of more than 99%, a good solution to this environmental problem.
The company in line with the green business philosophy, integrity-based business principles, continue to study and implement the guiding ideology of the 19th Party Congress "green water and green mountains is the silver mountain" for the motherland's environmental protection cause, welcome people from all walks of life to our company to visit.
