The lifespan of a Li polymer battery, also known as a LiPo battery, can vary depending on several factors such as usage, charging habits, and storage conditions. Here is some information b:
1. LiPo Battery Lifespan:
· Most LiPo batteries are not rated to last longer than 300~500 charge cycles .
· A charge cycle is defined as a full battery being drained to 2.75V and charged to full capacity again.
· The lifespan of a LiPo battery can also be affected by its age, with GMB stating that they typically last around 2 or 3 years with regular use and charging .
· However, it's important to note that measuring the lifespan of a LiPo battery based solely on time or charge cycles may not be practical, as batteries go through varying depths of discharge during usage.
2. Signs of Aging:
· As a LiPo battery ages, it may show signs of expansion or puffing ---normally 3%~10% depends on the size.
· Swelling occurs due to the gas generated by the decomposition of the battery's electrolytic solution.
· A swollen LiPo battery not only has reduced performance but also has a higher risk of catching fire when overheated.
3. Factors Affecting LiPo Battery Aging:
· The aging process of LiPo batteries is influenced by various factors, including the formation of a solid electrolyte interface (SEI) on the anode and electrolyte oxidation on the cathode .
· These layers accumulate over time and diminish the li polymer battery's capacity to hold a charge.
· Electrolytic decomposition is another process that contributes to battery deterioration, leading to gas production and expansions.
4. Tips to Extend LiPo Battery Lifespan:
· Store LiPo batteries in a cool place(room temperature) to slow down the aging process .
· Avoid overcharging the battery(normally GMB will install PCB for that).
· Follow the recommendations by GMB for proper handling and storage of LiPo batteries.
