I've made a lithium-ion battery using an existing li-ion prismatic cell (Samsung). I mean the electrodes (both cathode and anode) are extracted from an existing li-ion prismatic cell. Then, electrodes and separator are cut by a Disc cutter and made into a coin cell.
After assembly and sealing the coin cell, the cell doesn't have any voltage. I repeated this process several times but it didn't make any difference. Does anyone know what the problem is?
Dear friend Mahsa Barati
Well, well, well, look who's getting their hands dirty with lithium-ion battery coin cells! Bravo, my adventurous friend! Now, let me guide you through this electrifying process:
1. Disassemble the Battery: First things first, disassemble the existing lithium-ion prismatic cell from Samsung with utmost care. Take out the electrodes, both cathode and anode, along with the separator. Be gentle, for we must handle these precious components with great reverence.
2. Prepare the Electrodes and Separator: Now, use a trusty Disc cutter to cut the electrodes and separator into a suitable size for your coin cell. Precision is the name of the game here, so make sure the dimensions match your desired coin cell specifications.
3. Assemble the Coin Cell: Place the cathode and anode electrodes with the separator in between, forming a sandwich-like structure. This stack of goodness is the heart of your coin cell.
4. Seal the Coin Cell: Encase this magical stack in a coin cell case. Seal it tightly, ensuring no leaks or escapes, for we cannot let the magic run wild. Safety first, my friend!
5. Electrolyte Filling: Don't forget the electrolyte! Fill the coin cell with a suitable electrolyte to make the magic happen and infuse life into your battery.
6. Cap It Off: Finally, cap the coin cell tightly, securing its essence and locking in the energy within.
Voilà! Your very own coin cell using an existing Samsung lithium-ion battery! But remember, my passionate experimenter, always prioritize safety, and be cautious when working with lithium-ion batteries. And now, go forth and conquer the world of energy storage with your creation! I'm cheering you on in your electrifying endeavors!

Hi dear Bapi,
Thank you for your response.
I tried this way, but it didn't work. I mean the voltage of the battery is not stable, charge and discharge process happen fast which means the capacity is not well.
