Lithium-ion batteries are the ultra-modern power source for most consumer electronic devices. Current collectors are essential components that connect lithium-ion batteries to external circuits, greatly influencing the capacity, rate capability, and long-term stability of lithium-ion batteries. Conventional current collectors, Al and Cu foils, have been used since the first commercial lithium-ion battery, and the thickness of these current collectors has decreased over the last two decades to increase energy density.

Battery packaging materials are critical in the production of lithium-ion batteries. Indeed, significant cost savings can be realised when the chosen packaging material has an adequate combination of mechanical, permeation, and seal-strength properties.

A battery separator is a polymeric membrane that sits between the positively charged anode and the negatively charged cathode of a battery. This positioning aids in the prevention of electrical short circuits.
