Cell Expansion

As you charge a cell it expands, when you discharge a cell it contracts and as the cell ages over its lifetime we see a continuing cell expansion. Thus the cell expansion can be divided into: The reversible cell expansion comes from changes in graphite layer spacing associated with different graphite-lithium intercalation compounds induce reversible … Read more
