The concept of Grade (class) is a term often misunderstood and misused in the lithium-ion battery industry. Manufacturers usually add classification codes such as A Grade, B Grade, or C Grade on cell labels to indicate the quality and performance level of the cells. In...
For lithium-ion batteries to be used safely, protection circuits are essential. One of the crucial functions of protection circuits is to balance the cells. In batteries with multiple cells connected in series, differences in electrochemical characteristics can lead to voltage imbalances during charge and discharge...
To create a battery pack, it's necessary to connect the battery cells with conductors. Typically, this connection is achieved through a process called spot welding or spot soldering. Spot welding involves passing a high current through the conductive material for a brief moment. During this process,...
Intervention in Lithium-Ion Battery Fires As known, lithium-ion batteries can experience combustion or explosion in cases of manufacturing defects or improper usage. The combustion and explosion of lithium-ion batteries are typically observed under the following circumstances: Short-circuiting or over-discharging the batteries with currents exceeding their capabilities, Physical damage such...
