One of the components in electronic devices that is difficult to upgrade is the battery. The development of lithium-ion battery technology is seen to come with ways to get more efficient runs, and recently, a research has been shown that seems to increase that efficiency even more.
A group of researchers from Dalhouse University in Canada led by Anu Adamson has released a research report stating that changing the PET (polyethylene terephthalate) tape to PP (polypropylene) tape to bind the lithium-ion cells is seen to reduce the battery's inactive discharge by 70 percent, and increase the lifespan of the battery itself by 10 percent.
According to Adamson, these two tapes have the same durability to ensure these lithium-ion batteries to work well when used in the first place. The difference can be seen when the PET tape goes through the de-polymerization process to become dimethyl terephthalate, which is seen to cause the discharge issue to be worse.
The research found that the use of PP tape reduced this discharge issue dramatically, and did not face the de-polymerization issue faced by PET tape.
In fact, Adamson says that the cost of PET and PP tapes are the same, so device battery companies will not face the issue of converting PET tape to PP tape for batteries of various types of electronic devices in the near future.
