Key Concepts

Electrolyte Breakdown

Electrolyte breakdown occurs when the electrolyte degrades due to chemical reactions or thermal instability, leading to reduced ionic conductivity and battery performance. This factor is pivotal in determining the efficiency and lifespan of batteries.

Electrode Material Wear

The wear of electrode materials, whether from mechanical stress or chemical reactions, significantly affects the battery’s ability to store and release energy. Over time, electrode deterioration can lead to increased internal resistance, reducing overall efficiency.

Formation of Dendrites

In lithium-metal batteries, dendrites, which are needle-like structures, can form during charging. This growth can penetrate the separator, leading to short circuits and battery failure. Understanding dendrite formation is essential for developing safer lithium-based energy storage solutions.
