Thermal events can destabilise the SEI and cause it to decompose and compromise the battery’s safety. An electrically insulating porous layer in a LIB that prevents the anode and cathode touching, which would cause a short circuit. State-of-health is a measure of the condition of a battery, compared to its ideal condition.
Why does a mobile phone battery deteriorate over time?
Over time, the resulting loss of active lithium available for charge-carrying is the reason battery performance deteriorates. This is commonly referred to as ‘battery ageing’. Consumers notice this when, after a few years of use, a device like a mobile phone needs to be charged more frequently than it had previously.
What causes a battery to age prematurely?
Several factors can impede this free movement and can cause a battery to prematurely age and degrade its state-of-health (SoH). Over time, successive charging and discharging causes damage to the battery’s materials. The usage conditions when recharging the battery – for example, frequent rapid charging – can accelerate the damage.
