Diaphragm with a dense porous structure, which allows it to achieve a more uniform pore distribution which in turn can reduce internal resistance and improve discharge performance of our batteries.
Surface SEM image
Section SEM portraitThe surface-coated nano-ceramic battery separator has the advantages of high temperature resistance, high voltage resistance, high puncture and high liquid absorption, which can greatly improve the heat shrinkage of the diaphragm and improve the safety and reliability of the battery.
According to UL1642 heating for 30min (hot oven 130°C).
Cell opening, no fire, no explosion, weight loss ≤ 10%.The 9um diaphragm reduces the internal resistance of the battery and increases the volumetric energy density of the battery
Comparison of different temperature discharge curves of low temperature batteries.
The cells were storaged at 70 ℃ for 7 days, variation of thickness <5%, recovery capacity >90%.
There is few agglomerate in CNT Solution.
In Electrode, CNT is well distributed on the surface of active materials.
We will do our best to make it happen since we don't shy away from challenges, so go ahead and just fill out this form.
