I am trying to fabricate full cell to evaluate performance of my Sn based alloy anodes. Currently I have tried LiMnO2 based cathodes but not able to obtain stable OCV after charging. I am using a combination of CC-CV mode for charging in this case. However, after charging, OCV drops rapidly and I am not able to obtain charge discharge profiles. Is there any particular protocol to be followed for alloy anodes? What is the ideal cathode material in this case? My anodic half cell performance is quite good and hence mostly there is no issues with the anode.
dear Sai Gourang Patnaik ;
the advantages of using Tin-based compounds in the field of LIBs is its low cost for synthesis and rich source compared with silicon and germanium. for cathode you can use one of the following electrodes LiMn2O4, LiCoO2, and LiNiO2

Dear Dr.Mahmood,
Appreciate your response. I did try LiMn2O4 already but not able to obtain stable OCV after charging. Do you have any tips for me for the charging protocol?
Thank you.
Sai
dear Sai Gourang Patnaik ;
you have to follow a specific charging technique I think this video is helpful for you.
