I am new to PE for lithium battery. In the last weeks I assembed half cell to test standard LFP material. However I got all my OCP initially at ~3.2v but then reduce to ~1.5V with quick shift down. I tried to charge some of them, but I also got failure....
Anyone to help? really appreciate.
I assembed my cell in glove box in Argon. The electrodes were dried in vacuum oven at 120 dgree for 16 hours as asked by my instructor.
