Lithium-ion batteries (LIBs) are widely used in various mobile electronic devices due to their high energy density and eco-friendliness. The application of colloidal materials in LIB electrodes is also constantly being refreshed. The processability of colloidal nanoparticles holds great advantages for the fabrication of complex devices and large-scale production methods. Alfa Chemistry can provide size- and shape-controlled colloidal nanoparticles synthesized from a variety of materials for LIB electrodes.
Common cathode materials in lithium-ion batteries include LiCoO2, LiMn2O4, LiFePO4 and Li3V2 (PO4), and common anode materials include graphite and silicon materials. The above electrode materials have their own advantages and disadvantages. For example, LiMn2O4 is cheap and safe, but Mn3+ has a distortion effect, resulting in serious capacity decay; graphite has good cycle performance, but high potential and low energy density. The battery electrodes prepared based on colloidal materials or colloidal technology can exhibit excellent electrochemical performance. Colloidal electrodes can greatly shorten the diffusion length of ion transport and can adapt to strain through cycling. Colloidal materials are emerging as ideal building blocks for creating and designing LIB electrodes with enhanced electrochemical performance. Their processability is a great advantage for the fabrication of complex devices and large-scale production methods.
