PRCDMS Software:

1.Pressure can be set willfully within the extent of max pressure.

2.The resistivity under different pressure can be measured in succession with controllable rate and interval of pressure scan.

3.Different data analysis curves can be generated, including resistivity-pressure curve, resistivity-thickness curve, Compact density-pressure curve, and pressure-thickness curve.

4.Two resistance data collection modes: interval time mode or automatic steady state condition determine mode.

5.Data statistical analysis functions.

6.Automatic generation of reports with the value of resistivity (or conductivity) and Compact density.

Integrated design :Integration of control and measurement systems for pressure, resistivity and thickness control and measurement systems.

Application Case（Contact us for more information）

(1) LCO MATERIAL ASSESSMENT     

Evaluation of electrical properties of modified powder(LCO)

Parameter: 10~200MPa, 5MPa steps, keep 15s

Results: When the Compact density of the modified powder is greater than 3.87g/cm3 (applied pressure＞75MPa), the conductivity of the modified powder is greatly improved. The effectiveness of the modification can be evaluated.

(2) NCM MATERIAL ASSESSMENT

Results Analyze

•By adjusting the Ni content in the ternary material, the powder conductivity increases with the increase of Ni content.

•Compared with three kinds of ternary electrodes with different Ni content, the conductivity of the electrode increases with the increasing of Ni content;

Powder resistivity and electrode have the same trend!

(3) LFP MATERIAL ASSESSMENT

Results Analyze

•Compared with the LFP powder and electrode sheet under four different modification conditions, the conductivity trend of LFP powder and electrode sheet is as follows

LFP-1>LFP-2>LFP-3>LFP-4

Powder resistivity and electrode have the same trend!
