Among them, the reasons for the bulge caused by overcharge and overdischarge are as follows: Overcharge will cause the lithium ions of the positive electrode material to run into the negative electrode material, resulting in the deformation and collapse of the positive. . Among them, the reasons for the bulge caused by overcharge and overdischarge are as follows: Overcharge will cause the lithium ions of the positive electrode material to run into the negative electrode material, resulting in the deformation and collapse of the positive. . So why do lithium batteries bulge? The main material composition of lithium battery pack: positive electrode material, negative electrode material, electrolyte, diaphragm (isolation material) composition. Positive electrode materials occupy an important position in lithium batteries, usually. . However, one common issue that users may encounter is battery bulging, where the battery case swells or expands. This phenomenon not only affects the device's appearance but can also pose safety hazards. Understanding the causes of lithium battery bulging and knowing how to handle it is crucial for. . This article analyzes the causes and hazards of lithium-ion battery bulging in detail and provide practical preventive measures to help users use lithium batteries more safely and effectively. While these power sources revolutionized modern electronics, their chemical instability can turn everyday devices into hazards.
