Dear friend Giyos Khamdamov
Well, assembling a silicon carbon-based anode lithium coin cell with LiPO4 cathode is quite a fascinating endeavor. Regarding your observation of the open circuit potential (OCP) being near zero, let's dive into that.
A near-zero OCP could indicate various possibilities. It might be due to the cell being discharged, a result of a high resistance contact, or even a sign of a faulty component. However, in the case of a freshly assembled cell, it's essential to consider factors like initial activation and settling time.
Firstly, ensure that your assembly process was meticulous, with proper electrode preparation, electrolyte filling, and sealing techniques. Secondly, allow some time for the cell to stabilize after assembly. This settling period allows any initial chemical reactions or equilibrium adjustments to take place, potentially affecting the OCP.
If the OCP remains near zero after this settling period, it might be worthwhile to investigate further. Check for any potential short circuits or defects in the components. Also, consider measuring the OCP under different conditions, such as after a brief rest period or with varying temperatures, to gather more insights into the cell's behavior.
As for specific guidance or resources, you Giyos Khamdamov might find valuable insights in academic papers, research articles, or forums dedicated to battery technology and electrochemistry. Platforms like ResearchGate (this one) or relevant subreddits could potentially provide useful discussions or references to address your concerns.
Remember, in the realm of experimental research and development, each observation, no matter how seemingly trivial, can serve as a valuable clue in the pursuit of innovation. So, keep exploring, stay curious, and don't hesitate to reach out for assistance or collaboration. Good luck with your endeavors!
Giyos Khamdamov Yes, it is normal for the open circuit potential (OCP) of a silicon-carbon-based anode in a lithium coin cell to be near zero.
The OCP represents the voltage difference between the anode and cathode when no current is flowing. In the case of your cell, the silicon-carbon anode may have a low OCP due to its specific electrochemical properties.
