Evidence has accumulated recently that a high-capacity electrode of a lithium-ion battery may not recover its initial shape after a cycle of charge and discharge. Such a plastic behavior is studied here by formulating a theory that couples large amounts of lithiation and deformation.
Capacity in lithium-ion batteries is typically measured in milliampere-hours or mAh. This unit of measurement represents the amount of current that a battery can provide over a given time period. A 1,000 mAh battery, for example, can deliver a current of 1 milliampere (mA) for 1,000 hours or a current of 100 mA for 10 hours.
