What is the Nernst equation for a lithium ion battery?
We have used the Nernst Equation, in the chart above, to capture a lithium ion battery with a 3.7V Standard Potential. Cell Voltage matches Standard Potential when the concentration of Li+ in solution matches the concentration of Li intercalated at the anode. Here [LiC6] = [LiMxOy]. Hence [LiMxOy]/ [LiC6] = 1. Hence ln (1) = 0. Hence E = E0.
What causes lithium ion battery degradation?
Battery degradation occurs when lithium ion batteries are over-discharged, such as dissolution of the copper current collector at the anode. As the battery is charged, most of the LiC6 sites have already been occupied at the anode, and there is little LiMxOy left to dissociate at the cathode.
Why do lithium ion batteries run out suddenly?
This is why users sometimes report batteries “running out quite suddenly”. The cutoff voltage for a lithium ion battery is around 3V. Battery degradation occurs when lithium ion batteries are over-discharged, such as dissolution of the copper current collector at the anode.
Is lithium fluoride a high voltage electrochemical cell?
Lithium Fluoride would be one of the highest voltage electrochemical cells possible, with a Standard Potential of 5.9V, because lithium is one of the strongest reducing agents and fluorine is one of the strongest oxidizing agents. Wikipedia maintains a useful list of Standard Potentials.
Is lithium a reducing agent?
Lithium is one of the strongest reducing agents in chemistry with a Standard Potential of -3.04 Volts (relative to the H2/H+ redox pair). Schematic illustrating the Standard Potential for a hypothetical Lithium-Hydrogen battery including Standard Potentials
What is the thermodynamic result of Li + H+ -> Li+ 0.5 H2?
The chemical reaction is Li + H+ -> Li+ 0.5 H2. The thermodynamic result is that energy has been released by this reaction. The energy is imparted to the electrons that were ‘pushed out’ from the Li-side of the cell. Remember that 1 Volt simply means 1 Joule of energy per Coulomb of charge, where the elementary charge of 1 electron is 1.602×10^-19.
