Replacing tape used to make lithium-ion batteries could slow battery degradation and reduce self-discharge

A team of chemists and physicists at Dalhousie University in Canada has found that replacing the type of tape used to make lithium-ion batteries could slow battery degradation and reduce the amount of self-discharge in smartphones and other personal devices. In their project, reported in the journal Nature Materials, the group studied the behavior over time of polyethylene terephthalate (PET) tape used to make lithium-ion batteries in smartphones.
