we also cansupply 18 20 25um separator
2.SEMpicture:
In the SEM picture, itsmagnification factor is 20, 000 times, the scaleplate is 1 um, andthe aperture is uniform, the diameter is about 0.1um.
3.separator(16um) aperture profile:
The aperture distribute during 100-1000 A, 0.001-0.1 um, mostly isnearly 0.03 um.
4. part of ion exchange separator battery testing performanceparameters:
4.1different rate discharge curve:
4.2 testingmethode:
1) the battery all charging from 1c (920 mA) to 4.2 v/ 20mA.
2) discharge to 3.0 v by 0.2 c, 0.5c, 1c, 2c, 3c, then recorddischarge capacity of different current.
3) calculate every discharge rate.
| .5C(%) | 99.1 |
| 1C(%) | 98.8 |
| 2C(%) | 96.3 |
| 3C(%) | 94.1 |
4.3the cycle curve:
testingmethode:
In the normal temperature, the battery charge and discharge with 1c(920mA) . charging until the current is 10 mA, discharging untilthe voltage is 3.0v.
cycle reciprocating to 80% of original capacity, record therelationship of capacity and cycle times.
