Battery Swelling Analysis

Introduction How can high-temperature performance be improved? To make it easier for readers to follow and understand, the editor from Iray Energy will break this question down into several perspectives. 1. Control of Water Content Although moisture is only a minor impurity in lithium-ion batteries, it has a significant negative impact on high-temperature performance. The…

Introduction In the previous article on standards, the editor from Iray Energy shared the testing conditions for lithium-ion batteries under high temperature, and pointed out that the main performance degradations after high-temperature storage include capacity fade, thickness swelling, and increased internal resistance. This naturally brings up the following question: What exactly happens inside a lithium-ion…
