Construction |
The cell is made of anode、cathode、electrolyte、separator、metal can.
A.There are 2 types for the manufacturing of anode, including Powder type and Coating Type. Powder type is to compress the hybrid of MnO2 powder、Carbon powder、synthetic resin; The Coating type is to coat MnO2 and Carbon powder bond onto the current collector, form the thin film electrode after heated.
B.Negative material is Li. The active material of Positive pole is electrolytic Mno2 powder
C.The electrolyte is LiCLO4 dissolved in PC and （1，2-DME）mixed in organic solvent |
Electrochemical Processes |
Chemical reaction |
Li-MnO2 batteries follow the same electrochemical system. The reaction during current flow are :
（—）Li | LiClO4 ，PC + DME | MnO2（C）.（ + ）
At the cathode ：Li —→Li+ + e
At the anode ：MnO2 + Li+ + e —→ MnOOLi
General reaction ：Li + MnO2 —→ MnOOLi
The reaction result is Li,Li enters into the crystal lattice of MnO2 .Mn in Mnooli is +3 |
