Is it better to use lithium-ion batteries or polymer batteries for portable power banks?

1. Lithium-ion batteries are characterized by light weight, easy to carry, charging and discharging by the transfer of lithium, and generally doped with lithium-ion metal oxides as electrodes. It can be charged. The batteries of many mobile phones and computers are generally lithium-ion batteries. This type of battery should be kept away from heat sources, prevent direct sunlight, and be properly charged, but not fully charged, as it can greatly improve the durability of lithium-ion batteries. 2. Lithium-ion polymer batteries are characterized by high energy density, ultra-thinness, and their internal materials are solid or colloidal solids, and will not leak liquid if the battery is damaged. Moreover, it is highly moldable and can adapt to different design requirements. Under the same circumstances, the performance of lithium-ion polymer batteries is 10% higher than that of lithium-ion batteries, but the relative production cost is also higher. Answer 1. It can be said that after years of development, the technology of lithium-ion batteries is relatively mature, and large-scale processing has made their manufacturing costs very low. Therefore, lithium-ion batteries have more advantages than lithium-ion polymer batteries in terms of price. This is why this type of battery is currently used in most notebook computers and other devices. Nowadays, the most common use of 18650 lithium-ion battery in steel shell is the most common mobile power supply. It has a high safety factor. The processing technology is very mature, and the price is cheaper than polymer batteries. It occupies most of the lithium-ion battery market share. The most common in computer batteries. The second answer is that polymer lithium-ion batteries are better. Lithium-ion polymer battery is an upgraded product of lithium-ion battery. Relative to the current popular lithium-ion battery, it has the advantages of large capacity, small size, and safety. But the price is also more expensive. The safety, operating temperature range, cycle life and environmental performance of polymer lithium-ion batteries are relatively good, so lithium-ion polymer battery cell mobile power sources are better.
