加拿大的一组科研人员发现了一种延长大多数笔记本电脑和手机电池寿命的新方法。主流笔记本电脑和手机所用的电池在固定时，会使用聚对苯二甲酸乙二醇酯（PET，一种合成树脂）制成的小胶带。哈利法克斯达尔豪斯大学电池实验室的研究小组于去年 11 月确定，这种类型的合成树脂会由于电池中的化学反应而溶解，导致其电荷耗尽而不发出电流，这一过程称为自放电。这也是为何满电的设备，即便是在关机状态下，电量也会慢慢流失的原因。研究人员发现，使用化学稳定的聚丙烯（PP）胶带之后，电池寿命可以延长 10%，最多可以减少自放电 70%。PP 上的化学键要比 PET 更强，也更稳定，而且依然能够固定电池。聚丙烯通常用于制造更耐用的塑料物品，如户外家具或可重复使用的水瓶。

A new method has been discovered to extend the battery life of most laptops and smartphones. The batteries used in these devices are typically made of polyethylene terephthalate (PET), a synthetic resin. However, this type of resin can dissolve due to chemical reactions in the battery, causing it to charge and discharge without emitting current, a process known as self-discharge. This is why even when the device is turned off, some of the charge will slowly 流失。Researchers have found that when chemical-stable polypropylene (PP) tape is used, battery life can be extended by 10%, and self-discharge can be reduced by up to 70%. PP has stronger chemical bonds than PET and is more stable, but can still fix the battery. Polypropylene is commonly used in the production of durable plastic items, such as outdoor furniture or reusable water bottles.
