Except for smartphones, most smart devices currently use lithium-ion batteries as a means of energy supply. No matter what, the power of lithium-ion batteries will pass over time. So how can we more effectively maintain the batteries and extend their lifespan?

After studying dozens of academic papers and manufacturers' manuals, a team at the University of Michigan, Ann Arbor, compiled a series of best practices to protect the lifespan of lithium-ion batteries as long as possible. Over time, almost all components of a battery will deteriorate, including the anode, cathode, electrolyte, diaphragm, and collector. In a new study, the research team identified several important factors that lead to battery degradation, all of which can be prevented.

Firstly, prevent exposure to high, gentle, and low temperatures, especially during charging. If your phone burns on the charger, please remove it. Similarly, prevent charging in extremely cold conditions. Extreme temperatures may accelerate the degradation of almost all battery packs. As a command, if the temperature exceeds the range of 10-35degC, please do not charge.

Secondly, the battery dislikes being too full or too low. Ideally, you should never let them charge more than 80% or discharge to less than 20%, as exceeding the range on either side can put pressure on lithium-ion batteries and cause them to deteriorate. If you want an overcharged battery, please continue to overcharge and once the battery reaches 100% capacity, immediately remove it from the charger.

Thirdly, if possible, please prevent rapid charging and discharging. A fast charger may seem convenient, but high current will heat and degrade the battery faster than slow current charging. The same applies to high discharge rates, as high power consumption can be detrimental to your battery and shorten its lifespan.

Finally, prevent the use or storage of lithium-ion batteries in damp environments and prevent mechanical damage such as puncture.
