Defective charging can happen as a result of faulty equipment or as a result of some of the other battery failure modes discussed in this document. PSOC operation is a growing trend due to the growing number of vehicle systems that rely on the battery to function correctly and the deep and micro-cycling that occurs in start-stop vehicles.
The main causes of these accidents include overheating, short circuit, overcharging, self-heating and mechanical damage. Due to the large number of hazardous accidents involving LIB shown in Table 10, some regulations have been made regarding the transportation and storage of batteries.
The result is grid wires become exposed to accelerated corrosive activity during charge. And over time, these conditions cause the battery to fail. In an acid stratified battery, shedding, corrosion, and sulphation happen much faster at the bottom of the plate, leading to earlier battery failure.
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.
Battery degradation occurs due to ageing mechanisms in its components and increases in internal resistance. It is collectively under-pinned by irreversible chemical and structural changes in battery components. Capacity fade is a gradual decrease in the amount of charge a battery can hold and occurs with repeated use as the battery ages.
Thermal events can destabilise the SEI and cause it to decompose and compromise the battery’s safety. An electrically insulating porous layer in a LIB that prevents the anode and cathode touching, which would cause a short circuit. State-of-health is a measure of the condition of a battery, compared to its ideal condition.
