Why do batteries lose capacity?

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!

Why do batteries degrade over time?

High temperatures can cause the battery's electrolyte to break down and accelerate chemical reactions within the battery, while cold temperatures can slow down chemical reactions, leading to decreased performance. Regardless of usage patterns, batteries degrade over time simply due to age.

What causes a battery to deteriorate?

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.

Why does a lithium ion battery lose inventory?

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.

Can a battery pack damage a e-bike?

Often, due to exposure to high voltage, uneven discharge, overheating, or even blunt force trauma, individual cells in a battery pack can take irreversible damage and cause the power system of the entire e-bike to be badly affected.

How does battery degradation affect energy storage?

This means that over time, a fully charged battery won't take you as far as it initially did. Similarly, in battery energy storage systems (BESS), battery degradation can limit the amount of energy that can be stored and delivered, impacting the overall efficiency of the system.
