Products Description
Sintering conditions: tube furnace 900°C/10h, oxygen atmosphere control required (for reference only).
The precursor itself does not contain lithium ions, and has no electrochemical properties such as gram capacity & efficiency;
When producing finished sintering, need to added lithium salts, additives, etc. And the amount of addition, mixing & sintering process, etc. will cause differences in electrochemical properties, so it is impossible to give a specific performance judgment, please be aware.
