LiPo/LiIon/LiFe Batteries

A Lithium-ion battery as well as other variations such as Lithium-polymer battery or Lithium-iron phosphate batteries are rechargeable (secondary cell) batteries in which lithium ions move from the anode to the cathode during discharge and back when charging. The rechargeable Li-ion, Li-Poly and LiFePO batteries are different from the standard Lithium batteries that are not rechargeable. The rechargeable Lithium-based batteries provide lightweight, high energy density power sources for a variety of devices and are becoming more and more popular and widely used in portable electronic devices such as mobile phones, game consoles, tablets and laptops. The lithium-ion batteries usually have a 3.6V or 3.7V nominal voltage, the LiFePO4 (LiFe in short) have a nominal voltage of about 3.2V or 3.3V and the lithium-polymer batteries have a nominal voltage of 3.7V per cell. With Li-ion and LiPo batteries the recommended per cell safety zone is usually between 3V (fully discharged) and 4.2V (fully charged), though you normally can discharge the batteries up to about 2.8V without problems, going below may damage them irreversibly, so these batteries often have built-in safeties not to be over-discharged, also overcharging can be dangerous. LiFe batteries are a bit different as they have a bit lower operating voltage of about 3.2V – 3.3V, the minimum discharge voltage is 2.8V and the maximum charged voltage is 3.6V. The LiFePo4 batteries have more constant discharge voltage are considered to offer better safety than other Lithium-based batteries. Other advantages of the Lithium-based rechargeable batteries include the ability for much faster charge and higher discharge rates than other chemistries mentioned and usually higher number of recharge cycles, meaning longer life when not fully discharged.
