Which 18650 lithium battery is safer than polymer lithium battery?

You can use the battery explosion as a key word, Du Niangzhi, the relevant critical news is related to mobile phones, but now mobile phones, there are no models with non-polymer lithium batteries. Therefore, polymer lithium batteries are compared with 18650 lithium batteries. The claim that the battery is safer is untenable, and there is no claim that it will never explode. Except for a few extreme explosion cases, the bulging phenomenon is almost a common problem of polymer lithium batteries. Of course, the polymer lithium battery has its magical and the 18650 (cylindrical) lithium battery is completely irreplaceable advantage: square and flat, which makes it show its talents in thin and light portable electronic devices, except for the highly dependent mobile phones, ultra-thin notebooks Lithium polymer batteries are also used here. No matter its security is high or low, as long as we can't do without the mobile phone, it is in your hand or in your trouser pocket. Fortunately, most of the current star models of mainstream mobile phone brands use Japanese and Korean batteries, all from international manufacturers, and the overall safety is very high, so you don't need to worry about it in daily use. Turning back to talk about 18650 lithium battery, this kind of ancient battery that is often attacked by various cottage mobile power manufacturers, is still widely used in various electronic devices, such as mobile power. In fact, in high-end applications, such as professional imaging equipment and laptop batteries, 18650 has always been the main role. The large-scale use of Tesla electric vehicles has enhanced the high-security image of this battery. The 18650 lithium battery has mature technology, good consistency, and high capacity density. It has the advantages that polymer lithium batteries cannot be replaced in large-capacity hybrid applications. So, when we need to consider the battery type in our daily life, what choice should we make? Take the mobile power supply as an example. My personal opinion is: choose products from well-known battery suppliers, such as: Sanyo, Panasonic, Sony, Samsung, LG, domestic Lishen, BAK, Yangtze River, Zhuoneng, etc. also have a certain scale of strength The safety of the brand is also relatively high. The safety of the battery cell lies in the quality control of the manufacturer, not whether it is a polymer or a general lithium battery. By the way, to correct a widely accepted false statement: polymer lithium battery does not mean lighter and thinner. Lightness or thickness has always been closely related to energy density. No matter whether the battery is cylindrical or square, there is no significant difference in volume and weight between polymer lithium batteries of the same capacity and 18650 lithium batteries in the same period.
