What are the advantages and disadvantages of using lithium cobalt oxide as a battery raw material?

Most consumer electronic products use lithium cobalt oxide as a battery raw material. 1. High safety: It cannot be denied that polymer batteries are relatively safer than 18650 batteries, or they are less dangerous and destructive. Under normal circumstances, polymer batteries are at most Bulging, rupture, and burning, which are directly destructive without explosion. 2. Larger capacity: Relative to general batteries, the polymer capacity is relatively large, with a gram capacity of 100/115mAh/g. 3. The shape is flexible and changeable: because the polymer is packaged in aluminum film and has no fixed shape, it is possible to manufacture flat batteries, or customize batteries of different shapes according to the needs of different customers to meet different requirements. , Very flexible. 4. Fast charging speed: Compared with other battery types, the charging speed of polymer batteries is much faster, and the discharge current is relatively stable. 5 Relatively lighter weight: Because of the hard-shell protection, polymer batteries are lighter than 18650 batteries of the same volume. Disadvantage 1, high cost: Compared with other batteries, the cost of polymer batteries is almost the highest, and it is concentrated on the electrolyte that is difficult to reduce. The high cost has become a major factor restricting the development of polymer batteries. 2. There is no fixed model: Due to the variability of the shape, although it is more adaptable to the market, it also leads to the lack of a unified model and the possibility of replacement, thus losing the continuity of the market. 3. Serious copycats: Due to the good future direction of polymer batteries, but the high manufacturing cost, there have been many knockoffs on the market after flattening 18650 batteries into polymer batteries, and there was a crisis of copycats at one time. 4. Low energy density: Compared with other lithium batteries, the energy density of polymers is relatively low, which has caused many processors to desperately compress safety protection in order to increase capacity.
