I have spent a lot of time writing about how battery wear is a fact of life, and the more a battery is used, the more it will wear. It is a consumable item, and it will wear.

But there are also things that we can do to prevent battery wear. A research paper led by Jihyun Hong at Postech and Jongsoon Kim at Sungkyunkwan University on EV (electric vehicle) batteries uncovers a new enemy -- too much discharge.
Discharging EV batteries harms them
Without getting too deep into the chemistry and physics of battery wear, the study discusses a newly identified mechanism of oxygen loss in layered oxide cathodes used in lithium-ion batteries, specifically during the discharge process at voltages below 3.0V. Because of this additional wear, the study emphasizes the importance of carefully setting DCOVs (discharge cut-off voltages) to slow down degradation and improve battery lon
