Because lithium-ion batteries can have a variety of positive and negative electrode materials, the energy density and voltage vary accordingly. The open-circuit voltage is higher than in aqueous batteries (such as lead–acid, nickel–metal hydride and nickel–cadmium). Internal resistance increases with both cycling and age, although this depends strongly on the voltage and temperature the batteries are stored at. Rising internal resi

However, the working voltage of a lithium-ion battery can range from 2.5V to 4.2V per cell, depending on the chemistry and design of the battery. It''s important to note that the maximum charge voltage of a lithium-ion battery should never exceed 4.2V per cell, as this can cause damage to the battery and even lead to safety hazards.
