The solid-liquid mixed lithium ion battery independently developed by Ganfeng LiEnergy. Base on the traditional anode and cathode materials, we replaces the traditional diaphragm with the flexible electrolyte membrane which independently developed by Ganfeng LiEnergy. It is a new generation of lithium battery with high energy density, high safety performance and long cycle life. In terms of safety performance, the test result of acupuncture, extrusion and thermal stability far exceed the national standards of safety requirements. According to the special environmental requirements, Ganfeng developed low-temperature battery which supports 1C / 1.5C cycle at - 10 ℃, and the discharge capacity can reach more than 60% at - 40 ℃. Our products have a variety of specifications, which can flexibly adapt to different applications such as power, energy storage, consumer electronics, etc. Ganfeng solid-state lithium ion battery has completed the national compulsory inspection and certification test, and currently we are cooperating closely with many vehicle manufacturers, and will realize mass production and vehicle application in 2022.
