my working electrode is O-LiMnO2...and electrolyte solution is lithium hexaflourophosphate in ethylene carbonate and dimethyl .carbonate
If you try to use LiMnO2 as the cathode material for LIBs. You'd better use metallic lithium as the counter electrode and reference electrode in a two electrode system. In this case, you can determine the Li ion storage capacity and potential of LiMnO2 accurately. If you try to use it in a three electrode system, Li ions might insert into grassy carbon and change its structure, making it unstable.
GC electrode is a kind of substrate upon which you can coat your active material and study. Use metallic lithium or some standard anode materials like graphite etc.
The charge consumed on the working electrode should be balanced by a reaction on the counter electrode. Only such materials can be used as counter electrodes.
Cheers
Yes, glassy carbon can be used as counter electrode in supercapacitors (pseudo-capacity) and Lithium-Ion Batteries. Glassy carbon is active anode material in both cases.
Thanks all for ur kind rply....
Mr. Jin Niu i have two electrode system..glassy carbon is used both as refernce and counter elctrode....
Dear Sergii Kuksenko thanks for ur kind rply..can u please suggest me some paper in which glassy carbon can be used as reference and counter electrode...
