Scientists have figured out why batteries self-discharge: This disadvantage is present in almost every one

A team of Canadian scientists from Dalhousie University has found the reason why the battery in almost every device in the world discharges on its own, even when the device is completely turned off, CBC reports. The defect is so common that it is found in almost every battery in the world.

The plastic tape used to organize the materials inside batteries is the culprit, as scientists have learned. The tape is usually made using the well-known PET plastic, and as a result of high temperatures, its parts break down when they enter the electrolyte. Scientists say that the monolith is broken, negative chemical processes begin to occur, and even when the device is turned off, there is a self-discharge.

Scientists have conducted numerous experiments at high temperatures simulating the charging / discharging of batteries and have confirmed this fact. Also, Canadians are curiously saying that this type of PET plastic component is used in almost all batteries in the world.

Some of the world’s largest battery and battery companies for electric vehicles have carefully studied the results of Canadian scientists’ experiments and are ready to correct this shortcoming by replacing an unreliable component.

Instead of PET plastic, the researchers suggest using another slightly more expensive, but not less common, polypropylene, which is used to make more reliable plastic products and is more resistant to chemical attack. It does not degrade as easily as PET and does not create unwanted chemical reactions.
