For lithium iron phosphate cells the nominal voltage is 3.6V and for ternary lithium & lithium manganate cells, it is 4.2V. Because of the use of graphite anodes, the voltage of lithium cells is dependent on the cathode materials.
WebWhile voltage-based SoC works reasonably well for a lead acid battery that has rested, the flat discharge curve of nickel- and lithium-based batteries renders the voltage method impracticable. The discharge voltage curves of Li-manganese, Li-phosphate and NMC are very flat, and 80 percent of the stored energy remains in the flat voltage profile.
