Applying nanomaterials to enhance the energy density of lithium-ion batteries

Abstract The technological improvement and commercialization of lithium-ion batteries have gone through a long period of development, and energy density is a crucial link in their development. At present, nanomaterials have made significant contributions to improving the energy density of batteries, while also effectively addressing some issues including safety and stability. Because of there will be some small size effects, such as an increase in conductivity, an enhancement of all mechanical, optical, and even superparamagnetic behaviour, when the size of the particles inside the material is reduced to match the wavelength of the electron, phonon, and Magnon. Scientists have also made targeted modifications to electrode and electrolyte materials based on these principles, using different technologies to improve the energy density and other electrochemical function of lithium-ion batteries. As a result, this research will start with the cathode, anode, and electrolyte materials of batteries, and explain the applications and principles of related nanomaterials.
