The nominal cell voltage of 3.60V can directly power mobile phones, tablets and digital cameras, offering simplifications and cost reductions over multi-cell designs. The drawbacks are the need for protection circuits to prevent abuse, as well as high price. Types of Lithium-ion Batteries
The movement of the lithium ions creates free electrons in the anode which creates a charge at the positive current collector. The electrical current then flows from the current collector through a device being powered (cell phone, computer, etc.) to the negative current collector. The separator blocks the flow of electrons inside the battery.
VOLTAGE PER CELL: Lithium-Ion batteries have a nominal voltage of 3.7 volts per cell. By using the cells in series, a battery pack can have any voltage possible in 3.7 volt steps. Ex. Lithium-Ion batteries use 3 cells to provide an 11.1 volt battery, 4 cells to provide a 14.8 volts battery or 10 cells to provide 37 volts battery.

The best storage voltage for lithium titanate oxide (LTO) cells is between 2.4V and 2.5V per cell, and for lead acid batteries, it''s around 3 volts per cell or 12 volts for a typical battery. Ideally, you should have a designated area that you use solely for lithium-ion battery storage. This ensures that the batteries are kept away from heat

Voltages. Depending on the design and chemistry of your lithium cell, you may see them sold under different nominal "voltages". For example, almost all lithium polymer batteries are 3.7V or 4.2V batteries.
The nominal voltage typically ranges from 3.6 to 3.7 volts per cell, but it''s important to note that discharging a lithium-ion battery below its minimum voltage can cause irreversible damage. Several factors influence the minimum voltage of a lithium-ion battery, including discharge rate, temperature, and load conditions.
Famous for their stability, safety, and extended cycle life, LiFePO4 batteries provide a nominal cell voltage of 3.2 volts. This contrasts with conventional lithium-ion batteries,
The voltage safety window depends on the chemistry of the battery, for example, a lithium-ion battery with LiFePO 4 cathode and graphite anode has a maximum charge voltage of 3.65 V and a minimum discharge voltage of 2.5 V, but with a LiCoO 2 cathode, the maximum charging voltage is 4.2 V and the minimum discharge voltage is 3.0 V.
