Lithium ion batteries infamously degrade over time. 1000 charges can cause up to 20% loss in capacity. Is there a type of rechargeable battery that will not degrade over time?
I recall people boasting in another forum that they have a particular type of secondary cell that is still going strong after a few decades of use. I think they were talking about the NiFe cell. You used to be able to buy them dry and you'd fill them with your own KOH solution. They were not sealed (in today's terminology), and not what you'd call high capacity.radaballer said:Lithium ion batteries infamously degrade over time. 1000 charges can cause up to 20% loss in capacity.

From memory, around 1.2V, but try a web search. Not sure whether you'd even be able to buy these now.
I bought one from a disposals store in the 70s. http://thumbnails112.imagebam.com/37333/0363e9373324851.jpg
Panasonic engineers report in paper that their Li (Ni,Co,Al)O2 based batteries suffer less than 10% loss after 3000 cycles. Cycle life is dependent on a couple of other factors. High temperature operation shortens life. So does rapid discharge, e.g. in an electric vehicle keeping the "pedal down" as a habit.radaballer said:Lithium ion batteries infamously degrade over time. 1000 charges can cause up to 20% loss in capacity.

The best type of battery for long-term use is a lithium-ion battery. These batteries have a longer lifespan compared to other types of batteries and have the ability to retain their capacity for a longer period of time.
The rate at which a battery loses its capacity depends on various factors such as usage, temperature, and storage conditions. In general, a lithium-ion battery can retain 80% of its capacity after 500 charge cycles.
While all batteries will eventually lose their capacity over time, lithium-ion batteries have been found to have the longest lifespan and retain their capacity for a longer period of time compared to other types of batteries.
There are certain precautions you can take to slow down the rate at which a battery loses its capacity. These include avoiding extreme temperatures, not overcharging or fully discharging the battery, and using the correct charger for the battery.
Yes, there can be differences in battery capacity between different brands. It is important to do research and choose a reputable brand that uses high-quality materials and has a good track record for producing long-lasting batteries.
