Advantages and disadvantages of lithium batteries compared to polymer lithium batteries

The advantage of lithium batteries depends on the high output power of charging and discharging. Under the same working voltage, the limit current exceeds the polymer lithium ion battery cell. In other words, the lithium battery has good output characteristics and high output power, and can be used in some machinery and equipment that must have a large amount of current in an instant, in order to ensure reliability. The defects of lithium batteries depend on their small volume, generally around 800MAH. In addition, lithium batteries are unstable under short-circuit failures and extreme external natural environments, and are very prone to explosions. When a lithium battery explodes due to short-circuit failures, the plastic shell on its surface is destructive. The advantages of polymer batteries depend on long battery life and large volume. The polymer lithium ion battery of the same volume has a volume 20% larger than that of a lithium battery, and has a strong endurance under the condition of stable current output. In addition, the surface layer of the polymer lithium ion battery is used as a soft raw material for the outer box. If the battery bulges due to a short-circuit failure, it is not easy to explode and always crack, so it is safe. Why are polymer lithium batteries more stable than lithium batteries? This starts with the structure of the two. Lithium-ion battery is a kind of rechargeable lithium-ion battery, which uses lithium-ion battery to move between positive and negative stages. In the whole process of battery charging, Li is intercalated and deintercalated between the two levels: when the battery is charged, Li is deintercalated from the positive stage, and the negative stage is placed in the negative stage according to the lithium-ion battery electrolyte, and the negative stage is in a lithium-rich condition; charge and discharge When the time is reversed. At this stage, there are two kinds of raw materials for the production of lithium-ion batteries, one is lithium cobalt oxide and the other is lithium iron phosphate. At the current stage, the cathode material for lithium-ion batteries on the market is generally lithium cobalt oxide, so lithium-ion batteries are also called lithium cobalt oxide batteries. In addition, there is also a lithium-ion battery made of lithium iron phosphate. Lithium iron phosphate has bright physical properties, short charging cycle for circulatory system batteries, easy to swell, and low operating characteristics. Consumer electronic devices generally do not use lithium-ion batteries made of lithium iron phosphate. As everyone knows, rechargeable batteries made of lithium cobalt oxide have a stable structure, have a higher specific volume than lithium iron phosphate, and are more expensive than lithium iron phosphate but have a higher safety factor. Therefore, most consumer electronic devices choose lithium cobalt oxide as Raw material for rechargeable batteries. Before mobile chargers became popular, the lithium-ion batteries that everyone could often touch should be laptop batteries. Perhaps you can think that laptop batteries are rectangular, while lithium-ion batteries are cylindrical. How are the two connected? The answer is how the power circuits are connected (series or series). This is what we usually call a 6-cell rechargeable battery.
