- We have been preparing some LFP | 1M LiPF6 in EC:DC electrolyte | Graphite pouch cells.
- We started to charge at C/20 CCCV until 3.8V. The battery was able to charge, but now it can't perform discharge, as it reaches 0V in a second;
- All materials are commercial, except for the electrolyte (some cells are done with 1M LiPF6 in EC:DMC and others are with a synthesized IL. We got the same results with both...
- we have tested LFP in half cell and it is working.
- When we assemble the pouch we get an OCV after assembly of +- 100 mV. we left the cell resting for 24h prior to preconditioning.
- Then we start a c/20 CCCV charge. we can't get a discharge though...
- However, after charging we are able to light up leds and keep the voltage at rest ...
