Lithium-ion batteries have high energy density, low self-discharge rates and long cycle life.<\/p>\n\n\n\n

They are used in smartphones, laptops and other portable devices and support our daily lives in unseen ways.<\/p>\n\n\n\n

Recently, there has been a growing trend towards installing them in electric vehicles and satellites.<\/p>\n\n\n\n

However, lithium-ion batteries cannot be used indefinitely and, like other rechargeable batteries, have a \u2018lifespan\u2019.<\/p>\n\n\n\n

This article describes the lifespan of lithium-ion batteries.<\/p>\n\n\n\n

This article also explains tips on how to make lithium-ion batteries last longer, which we hope you will read through to the end.<\/p>\n\n\n\n

Let\u2019s take a look.<\/p>\n\n\n\n

Lithium-ion batteries have a lifespan of around 2~3 years (300~500 cycles).<\/h2>\n\n\n\n

The lifespan of lithium-ion batteries depends on the conditions of use, but is said to be around 2-3 years for smartphones.<\/p>\n\n\n\n

If we define a single cycle as the process from a full charge to a complete discharge, performance begins to deteriorate significantly after approximately 300 to 500 charge-discharge cycles.<\/p>\n\n\n\n

There are four signs of lithium-ion battery degradation<\/p>\n\n\n\n
