Analysis of the advantages of polymer lithium batteries and liquid lithium batteries

①Good safety performance: The outer packaging is aluminum-plastic packaging, which is different from the metal shell of the liquid lithium battery. Due to the flexible packaging technology, the internal quality hazards can be immediately displayed through the deformation of the outer packaging. Once a safety hazard occurs, it will not explode. Will bulge; ②Ultra-thin design: suitable for all kinds of ultra-thin electrical appliances, and the liquid lithium battery has a technical bottleneck when the thickness is below 3.6mm. ③Light weight: polymer lithium battery is 40% lighter than steel shell liquid lithium of the same specification, and 20% lighter than aluminum shell liquid lithium; ④large capacity: polymer lithium battery has 10-15% higher capacity than steel shell liquid lithium of the same specification , 5-10% higher than the aluminum shell liquid lithium capacity; ⑤Small internal resistance: At present, the internal resistance of our products can be less than 35m, so that the battery capacity can be used more. The same capacity, in some designs, will Due to the difference in internal resistance, the use time differs by 20-50%; ⑥The shape can be customized: the thickness and shape of the battery can be flexibly customized according to customer requirements, and special shapes such as arcs can be made; ⑦Good discharge characteristics: polymer lithium battery Using colloidal electrolyte, it has a more stable discharge characteristic and a higher discharge platform. Because solid electrolytes are used instead of liquid electrolytes, compared with liquid lithium batteries, polymer lithium batteries have the advantages of being thinner, arbitrarily shaped, and arbitrarily shaped. Therefore, aluminum-plastic composite films can be used to make battery casings, which can improve The specific capacity of the entire battery. Polymer lithium batteries can also use polymers as cathode materials, and their mass specific energy will be more than 20% higher than current liquid lithium batteries. The polymer lithium battery has the characteristics of miniaturization, thinning, and light weight. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
