Description

technical field

[0001] The invention belongs to the technical field of lithium-ion battery electrode materials and preparation thereof, and in particular provides an electrospinning technology to synthesize lithium-ion battery cathode materials and a preparation method thereof. Background technique

[0002] Lithium-ion batteries have the advantages of high energy density, high power density, high working voltage, long cycle life, good safety performance, no memory effect, and no pollution. It is currently the most advanced green secondary battery. A lithium-ion battery generally includes a positive electrode, a negative electrode, a separator, and an electrolyte. Its working principle is that lithium ions are extracted and intercalated between the positive and negative electrode materials through the electrolyte, so the structure and performance of the electrolyte and electrode materials are key factors affecting battery performance and its price. At present, the common cat...
