The ternary polymer lithium battery is good. . . Shenzhen battery

lithium battery production and processing of using ternary material price continues to grow, causing the lithium battery manufacturers profit space continuous less and less, so a lot of lithium battery manufacturers to ternary lithium manganese battery research and development processing, because of the ternary lithium manganese battery can ensure high energy density on the other hand, on the other hand can reduce the cost of may, so the scheme of ternary mixed with manganese acid lithium battery anode materials become a lot of power battery manufacturer's secret. Now this ternary lithium batteries used in the product is good or bad, the price also rowed it out? And see us today for the analysis of the ternary polymer lithium battery is good.

lithium battery manufacturers use ternary mixed with lithium manganese acid solution can be to do the battery price is very low, according to the requirements of customers on the cost, the battery can be mixed ratio of manganese acid lithium as speak, therefore, have more very person do 5:5, cost down space can reach 5% Ranged between 15%.

the advantage of the ternary polymer lithium battery:

1, to reduce costs, at this stage the ternary lithium manganese acid lithium materials and the difference in 14 - 160000 yuan/ton, even considering the compaction density, manganese acid lithium addition to can reduce the cost of effect significantly;

2, can continue to improve the safety performance, structure itself than ternary lithium manganese acid lithium materials smoothly, mixed with manganese acid lithium can help the relatively large pure ternary battery capacity using the needle, overcharge safety performance test;

3, improve the performance of ratio of manganese acid lithium ratio performance is excellent, and the ternary mixed later can also improve the rate performance of the battery in the corresponding extent.

the defect of the ternary polymer lithium battery

1, manganese acid lithium compaction density is low, with the capacity of the whole chemical system will reduce, battery energy density also can have certain lower;

2. If the electrolyte collocation is not good, cycle life will be greatly reduced;

3, when the voltage is too low, the deadline for the submission of discharge part of ternary lithium manganese acid lithium ions could enter platform, 3 v lithium manganese acid structure were damaged, severe cases affect battery performance.

manganese acid lithium battery and ternary lithium battery which good?

the unique is the ratio of manganese acid tank performance is good, production is relatively simple, low cost. Defect is high temperature weather due to the dissolution of manganese to poor performance and cycle performance, using mixed with aluminum and sinter granulation, the heat performance and cycle caused the very big enhancement, basically can satisfy practical use. In general, manganese acid lithium battery low cost stability strong cold sex strong, the heat performance is poorer, attenuation coefficient slightly faster. Manganese acid lithium battery with ternary lithium battery pack say who good who bad, can't distinguish, the short time to look at what you use in the field and to use in the field of instantaneous power of the manganese acid battery is good, if you are using in the field of large capacity to use for a long time that is ternary lithium battery is good.

the ternary lithium manganese battery battery charging curve and ternary lithium battery is different, so the battery management system requires the corresponding adjustment. At the same time, the matching of the electrolyte is the biggest obstacle, the other does not change the composition of the condition, the only change electrolyte, for the performance of manganese acid lithium, especially the high temperature weather performance influence is very large.

the current China ternary lithium manganese battery owing to safety performance of the product stability, bottlenecks, such as specific energy density, cycle life field widely used with most used in low speed car, now popular new energy field of low end products such as electric bicycles, mobile charging treasure, there is few applications in the field of high-end power and digital.
