Hold onto your hats, folks, because the way you use your battery matters! High charge and discharge rates, keeping a battery at maximum capacity for extended periods, and frequent shallow discharging – these are all culprits that speed up capacity loss. Don’t underestimate the impact of Mother Nature on battery capacity!
This process is often accelerated by factors such as temperature and usage patterns. Each time a battery goes through a charging and discharging cycle, it undergoes stress that contributes to its degradation.
Their internal components degrade over time due to inevitable chemical reactions. Let’s delve into the nitty-gritty of this: Electrolyte Decomposition: The electrolyte, a key player in a battery, is prone to decomposition over time, which affects battery capacity.
This is because the chemical reactions that occur within the battery are not completely reversible, leading to a gradual loss of capacity and performance over the battery's lifespan. As a battery degrades, its capacity to hold charge diminishes, resulting in shorter battery life between charges.
Consumption of the cell’s lithium ions through SEI growth is one contributing factor to the degradation mode known as loss of lithium inventory (LLI). Because these reactions occur even when the cell is not in use, known as calendar aging, lithium-ion battery degradation is unavoidable.
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 aging is the effects of time on battery health.
