Energy storage battery manufacturers introduce the advantages and disadvantages of energy storage batteries

Energy storage battery core is also a kind of lithium ion battery. Different from the 18650 battery cell with liquid electrolyte, the polymer is a gel electrolyte, so it is also a lithium ion battery, but it is also distinguished from the 18650 battery cell. Energy storage batteries are widely used. Many mobile devices are currently powered by energy storage batteries, especially cell phones and mobile power sources. So what are the advantages and disadvantages of energy storage batteries? Energy storage battery manufacturers introduce the advantages of energy storage batteries: 1. High safety: It cannot be denied that, relatively speaking, energy storage batteries are safer than 18650 batteries, or the dangerous damage is not so great. Generally speaking, energy storage batteries only have Bulging, rupture and burning, no direct destructiveness caused by explosion. 2. Larger capacity: Compared with ordinary batteries, the polymer has a relatively large capacity, with a gram capacity as high as 100/115 mAh/g. 3. Flexible appearance: Because the polymer is packaged in aluminum film and has no fixed shape, it can be made into flat batteries, or customized batteries of different shapes according to the needs of different customers, so as to meet different needs very flexibly. 4. Fast charging speed: Compared with other battery types, the charging speed of energy storage batteries is faster and the discharge current is relatively stable. 5. Lighter weight: The energy storage battery is lighter than the 18650 battery due to its hard shell protection. Energy storage battery manufacturers introduce the disadvantages of energy storage batteries: 1. High cost: Compared with other batteries, the cost of energy storage batteries is almost the highest, and it is difficult to reduce the concentration on the electrolyte. The high cost has become a constraint on the development of energy storage batteries. The main factor. 2. There is no fixed model: Due to the variability of the shape, although it can better meet the needs of the market, it also leads to no unified model and no possibility of replacement, thus losing the continuity of the market. 3. Severe copycats: As the energy storage battery market has a bright future, but the manufacturing cost is high, there are many 18650 battery panels on the market that turn into energy storage batteries, and a copycat crisis once appeared. 4. Low energy density: Compared with other lithium-ion batteries, the energy density of polymers is relatively low, which has caused many manufacturers to desperately compress safety protection in order to increase capacity.
