When you charge a lithium-ion battery, the lithium ions move from the negative electrode to the positive electrode. This creates an imbalance in the electrons and causes degradation of the battery over time. The good news is that there are ways to help prolong the life of your lithium-ion battery.
Figure 2 outlines the range of causes of degradation in a LIB, which include physical, chemical, mechanical and electrochemical failure modes. The common unifier is the continual loss of lithium (the charge currency of a LIB). 3 The amount of energy stored by the battery in a given weight or volume.
Both modes of lithium loss reduce the charge “currency” or lithium inventory, and thus the battery’s capacity, because there will be a diminished amount of lithium freely available to convey charge between the positive and negative electrodes.
The good news is that lithium batteries usually don’t die suddenly. Instead, they slowly lose their capacity over time until they can no longer hold a charge. There are a few things that can cause a lithium battery to die prematurely. One is heat exposure. If a lithium battery gets too hot, it can start to degrade and lose its capacity quickly.
(ii) In a worst-case scenario, the metallic lithium can grow into branch-like structures called dendrites, which can protrude through the insulating separator and short-circuit the battery. This can cause a catastrophic failure mode, as has been seen in high-profile EV fires covered in the media.
The electrolyte is supposed to move only lithium ions, but hydrogen protons and electrons break off of molecules in the electrolyte and leak into the outer layers of the cathode, triggering a cascade of unwanted reactions that reduce battery life. Past explanations of energy loss in batteries focused on the movement of lithium ions.

Get PriceBattery degradation is a collection of events that leads to loss of performance over time, impairing the ability of the battery to store charge and deliver power. It is a successive and complex set of dynamic chemical and physical processes, slowly reducing the amount of mobile lithium ions or charge carriers.
