Polymer lithium battery strength and defect -Lithium - Ion Battery Equipment
The strength of the polymer lithium ion battery
1. Good safety performance. The polymer lithium -ion battery is used in the structure of aluminum -plastic soft packaging, which is different from the metal shell of the liquid battery cell. Once a safety hazard occurs, the lithium -ion battery is simply blasting.
2. The thickness of the thickness can be thinner, ultra -thin, and the thickness can be less than 1mm. It can be assembled in a credit card. The thickness of ordinary liquid lithium -ion batteries has a technical bottleneck below 3.6mm, while the 18650 battery has a standard volume.
3. Light weight, large capacity, battery with polymer electrolytes does not require metal shells to protect outer packaging, so when the capacity is the same, it is 40%lighter than the steel shell lithium battery, and 20%lighter than the aluminum shell battery. When the volume is generally large, the capacity of the polymer battery is larger, about 30%higher.(Lithium - Ion Battery Equipment)
4. The shape can be customized. The polymer battery can add or cut the thickness of the cell according to practical needs. For example, a new laptop of a famous brand is to choose a trapezoidal polymer battery to make full use of the internal space.
Polymer lithium -ion battery defect
(1) It is important that the cost is high, because it can be planned according to customer needs, and the development cost of the face here must be counted. In addition, the appearance and variety of types have caused the wrongdoing parts of various tooling fixtures in the production process, and the capital has also been added accordingly.
(2) The vertical battery itself is poor, which is also brought about by sensitive planning. Often, it is necessary to plan one for the client for the difference in 1mm.
(3) As long as it is broken, it will be abolished, and it is necessary to protect the line control. Overcoming or over -put will cause the reversibility of the internal chemicals of the battery to be damaged, which will seriously affect the life of the battery.
(4) Life is shorter than 18650, because different plans and materials are used, some have liquid inside, some are dry or collapsed, and the performance is not as good as the 18650 cylindrical battery during large current discharge.
