Here, we explore whether disposable e-cigarette cells are suitable for charge/discharge cycling, along with their response to damage. Cells harvested from disposable e-cigarettes showed impressive cycling performance, capable of over 700 cycles. When pierced with a nail, the exterior of the e-cigarette reached 270°C. This work highlights the waste of vital materials caused by the sale of disposable e-cigarettes and the urgent need for government intervention.
