Is it better to choose a lithium-ion battery or a polymer battery for the portable power bank?

Generally speaking, portable mobile power supplies use two types of batteries, one is a lithium battery, and the other is a lithium polymer battery. 1. Lithium batteries are characterized by light weight, easy to carry, and use lithium ion transfer to complete charging and discharging. Generally, doped lithium metal oxides are used as electrodes. It can be recharged. The batteries of many mobile phones and computers are generally lithium batteries. This type of battery should be kept away from heat sources, beware of direct sunlight, and properly charged, but not overflowing, as it can greatly improve the durability of lithium batteries. 2. Lithium 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 polymer batteries is 10% higher than that of lithium batteries, but the relative production cost is also higher. Answer 1. It can be said that after years of development, the technology of lithium batteries is relatively mature, and mass processing has made their manufacturing costs very low. Therefore, the price of lithium batteries has more advantages than lithium polymer batteries. This is why this type of battery is currently used in most notebook computers and other devices. At present, mobile power sources most commonly use steel shell 18650 lithium battery, which has a high safety factor, processing technology has been very mature, and the price is cheaper than polymer batteries, occupying most of the lithium battery market share, in notebook computer batteries The most common. The second answer is that polymer lithium batteries are better. Lithium polymer battery is an upgraded product of lithium battery. Relative to the current popular lithium 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 batteries are relatively good.
