With passing years, batteries are getting faster, efficient and more powerful than before. However, these tend to degrade or lose their power over time and use. They have positive and negative electrodes and electrolytes in them. Whenever the ions are moving between these positive and negatively charged electrodes, a chemical reaction takes place and current is produced. When lithium reacts with the iron phosphate, a crust begins to develop in the ion channels. This crust is best compared to salt crystals, which decreases the efficiency of the battery as it builds up over time.
Why do you have to charge a battery more frequently as it ages?
