3A The chemical Potential of Lithium In Pure Lithium Potential Is Lower Than The

Question

3A The chemical Potential of Lithium In Pure Lithium Potential Is Lower Than The Chemical Potential Of Li2O at Room Temperature Due To So Many Factors For Instance Consider This Example In Lithium Battery The Li+ Ions Have Highest Mobility Due to its Electropositive Nature And There Is Large Variation in Potential Difference And Voltage Due To This Large Variation The Pure Lithium Metal Has Low Chemical Potential And The Other factors Are 1.Temperature 2.High Capture Of Gases Like CO2 By Li2O.

4A The chemical Potential of Lithium In Pure Lithium Potential Is Higher Than The Chemical Potential Of LiFePO4 at Room Temperature Because LiFePO4 Has Lower Conductance However Conductance Can Be Increased By Doping Method adding Temperature Increasing Agents Like Glycine.

5A At Fermi Level VA-VB=uA-uB/-e Where VA & VB are Observed Difference At Two Points and uA & uB are Chemical Potentials For Example If We Take A=Pure Lithum Metal and B=Li2O at Room Temperature and 1 atmospheric Pressure and On Average They Are Equal.

6A The chemical Potential of Lithium In Pure Solid Lithium Potential at Room Temperature Is Higher Than The Chemical Potential Of Pure Solid Lithium at 00C. Because The Chemical Potential Is Directly Propotional to Temperature More The Room Temperature More The Chemical Potential.
