Overview of polymer lithium battery and lithium iron phosphate battery

by:Vglory      2021-03-07
Li-polymer batteries (Li-polymer) appear on the basis of lithium batteries with polymer electrolytes instead of traditional liquid organic electrolytes. This polymer electrolyte can be used as an ion-conducting medium and as an isolation membrane. In addition, the reactivity with metallic lithium is extremely low, so it effectively guards against the easy burning and easy leakage of lithium batteries. And because the lithium ion polymer battery absorbs the liquid organic electrolyte on a polymer matrix, it is called a colloidal electrolyte. This electrolyte is neither a free electrolyte nor a solid electrolyte, which makes the lithium-lithium polymer battery not only The excellent performance of liquid lithium batteries can also be made into ultra-thin products of any shape and size, making it widely applicable and promising for development. In addition, it is safer than lithium batteries. If it generates heat during use, it will only swell or burn, but will not explode. Lithium iron phosphate battery refers to a lithium battery that uses lithium iron phosphate as a positive electrode material. The cycle life of long-life lead-acid batteries is about 300 times, and the highest is 500 times for lithium iron phosphate batteries, while lithium iron phosphate power lithium ion batteries have a cycle life of more than 2000 times. Standard charging (5 hours rate) can reach 2000 times. Lead-acid batteries of the same quality are new for half a year, old for half a year, and for maintenance and maintenance for half a year, at most 1 to 1.5 years, while lithium iron phosphate batteries will be used for 7 to 8 years under the same conditions. Comprehensive consideration, the performance-price ratio will be more than 4 times that of lead-acid batteries. In addition, the polymer lithium battery (3.7v) is light in weight, and the voltage is higher than that of lithium iron phosphate (3.2v). The high temperature resistance coefficient is lower than that of lithium iron phosphate. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
