Prepare slurry and coat
1 hMix active material, conductive agent, and binder, then coat onto the current collector.
💡 Tip Vacuum degas for uniformity
⚠️ Caution Use NMP solvent in a fume hood

2
Punch and dry
1 hPunch electrode discs and vacuum-dry to remove moisture.
💡 Tip Vacuum dry at 110 °C overnight

3
Transfer to glovebox
30 minMove electrodes, separator, Li foil, and electrolyte into an Ar glovebox.
💡 Tip Keep H₂O/O₂ levels low
⚠️ Caution Electrolyte is moisture-sensitive; seal well

4
Assemble coin cell
30 minStack case/electrode/separator/Li/spring and crimp-seal.
💡 Tip Wet the separator evenly
⚠️ Caution Align separator to avoid shorting

5
Cycle test
Hours–daysRun galvanostatic cycling to record capacity and Coulombic efficiency.
💡 Tip Form with a small current first

⚠️ 5 Common Beginner Mistakes
- ① High glovebox moisture hurts capacity
- ② Cracking/delamination of the coating
- ③ Misaligned separator causes shorting
- ④ Insufficient electrolyte wets poorly
- ⑤ Incomplete drying leaves water
❓ FAQ
+Why is first-cycle efficiency low?
Irreversible Li loss during SEI formation.
+Fast capacity fade?
Check moisture, separator, and cycling range.
+Need rest before test?
Yes, rest 4–12 h to wet the separator.
