18650 lithium batteries and lithium polymer battery which is more secure?

Source: 2020 - 03 - 24 to pronounce hits: 18650 lithium batteries, lithium polymer battery: which one is more safe? It is generally believed that the polymer lithium-ion batteries more secure, and won't explode. As far as I know, polymer lithium battery more security mainly from taobao imitators of mobile power supply manufacturer, was sold on the basis of lithium polymer batteries, they chose 18650 battery products. We can put the 'battery burst as a key words, baidu, the main news related to mobile phone, and now the mobile phone, also didn't find the lithium-ion polymer battery model, so, polymer lithium battery safer than 18650 lithium batteries is untenable, and not necessarily not burst. Except for a few blasting of the extremes, bump phenomenon is common polymer lithium battery. Polymer lithium battery, of course, has its unique and irreplaceable advantages: completely it is square, flat, which makes it suitable for thin and portable electronic products, and we are highly dependent on the mobile phone and ultra-thin laptops. Whether it's security is high and low, as long as we can't leave mobile phones, it, in your hands may trouser. Fortunately, the mainstream mobile phone brand star models simply chose to Japan and South Korea series batteries, are from the world's largest factory, the overall safety is very high, daily use don't need to struggle with this. Back in 18650 lithium batteries, 'the old' battery often attacked by the various shanzhai mobile power supply manufacturer, but it is still widely used in mobile power supply, etc. Various kinds of electronic equipment. In fact, 18650 has been the high-end application of the main players, such as professional imaging equipment and laptop batteries. The large-scale application of the tesla electric vehicle, improve the image of the high security of this kind of battery. Type 18650 advanced lithium-ion battery technology, good consistency and high capacity density, in large capacity hybrid applications, polymer lithium battery can't replace. Therefore, when it comes to the types of batteries in our daily life, we should choose what kind of? Also in the mobile power supply, for example, personal idea is: select the product that well-known battery supplier, typical such as sanyo, panasonic, SONY, samsung, LG, guodian, bic, the Yangtze river, zhuo god also has a certain scale strength, ensure the security and has higher brand. The battery's safety depends on the manufacturer's quality control, more not depends on whether it is a polymer or ordinary lithium battery. Incidentally, correcting the mistakes of a widely accepted view: polymer lithium battery is not used for flight. Thin or thick traditionally associated with the energy density. Whether battery is cylindrical or square, with the capacity at the same time, using the volume and weight of the polymer lithium battery and 18650 there was no significant difference between the volume and weight of the lithium battery.
