Lithium-ion batteries are constantly degrading—even when they''re not in use—simply as a consequence of time and thermodynamics. This is referred to as calendar aging. Battery calendar
Customer Service
The aging of Li-ion batteries can be described by the loss of capacity and increase of internal resistance, leading to a decrease in energy density and power capability [8].
Customer Service
One of the primary culprits of battery decay is the uneven distribution of lithium ions. During repeated charging cycles, lithium collects in certain areas rather than dispersing evenly,
