This design is specifically designed for high current pulse applications and continuous high current discharge scenarios. The lithium negative electrode and positive electrode (thin, paste coated electrode on the conductive network) are wound in a "film" like structure with a microporous polypropylene diaphragm arranged between the two electrodes. The use of this design increases the surface area of the electrode, thereby improving the discharge rate capability of the battery.

　　High current wound structure batteries come with a safety valve that can release pressure in the event of abuse. Many of these batteries are also equipped with recoverable positive temperature coefficient (PTC) devices, which can limit current and prevent accidents caused by short circuits.
