The product test data curve




Storage requirements

1. When the battery is not in use, the optimal storage temperature is 25±5°C, and it can also be placed in a  cool and dry environment.

2.  After the battery is used, it should be charged in time and cannot be stored for a long  time. If the battery is not used for more than 3 months, the battery needs to be fully charged. If the battery is left unused for 6 months, it is best to perform a charge and discharge cycle. Regularly charging and discharging  the battery can ensure the health of the battery and prolong the service life of the battery.


Lithium iron phosphate battery coating uniformity problem

Uneven coating, not only the consistency of the lithium battery pack is not good, but also related to design,  safety and other issues. Therefore, the control of coating uniformity during the production of the lithium battery pack is very strict. Knowing the formulation and coating process, the smaller the material particles, the harder  it is to make the coating uniform. The fundamental improvement is from the material, such as increasing the conductivity, increasing the size of the particles, spheroidizing the particles, etc., and the effect may be limited  in a short time. Based on the existing materials, from the perspective of lithium battery processing, the improvement can be tried from the following:


The use of "linear" conductive agent: the use of "linear" conductive agent, currently mainly  VGCF (carbon fiber) and CNTs (carbon nanotubes), metal nanowires and so on.


Improve the dispersion effect: the slurry with good dispersion effect will greatly reduce the probability of particle  contact agglomeration, and the stability of the slurry will be greatly improved.


Improve the slurry transfer process: When the slurry is stored, consider increasing the stirring speed to avoid  the viscous slurry; for transferring the slurry using the turnover drum, shorten the time of discharge to coating as much as possible, and conditionally switch to pipeline transportation to improve The slurry is sticky.


Extrusion coating (spraying): extrusion coating can improve the surface of the blade coating, uneven thickness,  etc., but the equipment price is higher, the stability of the slurry is higher.
