What shortens the life of lithium batteries?

The high temperature increases the internal pressure of the battery, which causes a loss of water in the battery, which will reduce battery activity and accelerate the softening of the plate. And then shorten battery life. If the temperature is too low, the discharge capacity of the lithium-ion battery will decrease. Because the decrease in the ionic conductivity of the electrolyte will cause a rapid increase in the internal resistance of the battery and then result in poor output performance, for lithium-ion batteries, the range of 0 to 40 ℃ is optimal.

That's why it's so important to understand exactly how to care for and extend the life of the lithium battery. The following is a graph that describes the relationship between internal resistance and lithium-ion cell cycle times. One of the benefits of using a lithium battery is that they offer fast recharging, so there's no need to interfere with the process. Lithium-ion batteries are designed to retain their capacity even after being stored for months or years.

Never use a standard household power adapter because they have different voltage requirements than lithium-ion batteries. According to most manufacturers, the lifespan of a lithium-ion battery is about 5 years or at least 2,000 charge cycles. Extending battery life reduces the costs and environmental burdens associated with the production of new batteries, including the consumption of materials, the impacts of mining and greenhouse gas emissions, as well as the disposal of used batteries. To perform at their best, lithium-ion batteries require a specific temperature range or optimal temperature of 20°C to 60°C.

Lithium batteries are at the forefront of nickel-cadmium batteries, thanks to their stability and relatively low-maintenance nature. In a given discharge system, before the capacity of the secondary battery drops to a specific value, the number of cycles that the battery can withstand is called the life cycle or service cycle of the battery. Unlike other types of batteries that must be recharged during their storage time, lithium batteries perform best with a DOD (depth of discharge) of 40 to 50%. The number of life cycles in this standard does not mean that the battery can no longer be used, but that after many cycles, the storage capacity of the battery decreases to a certain extent.

Whether you want to power the devices in your home or buy a machine or vehicle that runs on lithium-ion, knowing how long a lithium-ion battery will last is an important question before buying one. Getting the battery up and running as soon as possible can be tempting, but charging quickly can damage the battery and shorten its lifespan. As a lithium-ion battery ages, it irreversibly loses capacity, affecting how long it can hold a charge.
