Therefore, an abnormal increase in maximum surface temperature during overcharging can serve as a predictor of impending cell failure. Fig. 7. Analysis of the causes of battery failure: (a) CT view of the normal cell; (b) CT view of the failed cell; (c) cyclic voltammetry curve of the intermittent overcharging aged cathode. Scheme 1.
Charging a battery at a high voltage accelerates corrosion and increases the rate of self-discharge. Battery manufacturers specify a charging voltage range for the battery, and charging outside of this range can cause sulfation and make the battery plates lose the active material that makes it work.
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.
Catastrophic failures often result in venting of the electrolyte, fire, or explosion. This is usually due to an overstress condition where the battery is abused or operated outside of its recommended voltage, current, or temperature limits , , .
The excessive current flow into the lithium-ion cell causes overheating and lithium plating, which leads to battery failure. When the current is in excess, the excessive joules will initiate more heat into the cell, causing overheating. The overheating leads to increased cell temperature hence failure.
A faulty charging system will not maintain the battery at full charge. Severe undercharging allows sulfate on the plates to become hard and impossible to remove by normal charging. The undercharged battery may fail to deliver the required power needed for its application. Over discharge Over discharge leads to hydration.
