The Correct Choice Of Rechargeable Lithium Batteries
Sep 27, 2017

Factors determining the cycle life or service life of lithium ion batteries precautions for lithium ion battery charging termination method Lithium Ion Charging application Example solution: Lithium ion Charging linear solution Lithium ion charge cycle waveform analysis, switching charging solution, in some applications, longer battery life, More charge times or safer batteries are more important than battery capacity. This paper introduces several charging and discharging methods of lithium ion battery which can prolong battery life greatly.Rechargeable Lithium Batteries

Almost all High-performance portable products use rechargeable lithium-ion batteries, including lithium-ion polymer batteries, this is because compared with other rechargeable batteries, lithium-ion batteries have a higher energy density, higher battery voltage, less self-discharge, very long cycle life, and environmental protection, and simple charging and maintenance.Rechargeable Lithium Batteries

The recommended method for charging lithium-ion batteries is to provide a constant current with a ±1% limiting voltage to the battery until the battery is fully charged and then stopped charging. The methods used to determine when the battery will be filled are: give the total charge time, monitor the charging current or both.Rechargeable Lithium Batteries

The first method uses constant voltage limiting current, ranging from C/2 to 1C, which lasts 2.5 to 3 hours, allowing the battery to reach 100% charge. You can also use a lower charge current, but it will take longer. The second method is similar to the first, except that the charging current needs to be monitored. As the battery charges, the voltage goes up, which is exactly the same as when the first method is used.Rechargeable Lithium Batteries
