Introducing nanomaterials to enhance the performance of lithium batteries

Since human society entered the electrical era, electricity has become an indispensable part in people’s lives, and the battery as the carrier of electricity, whether in the car, or people’s daily lives have a vital role. Since the birth of the first lithium battery, lithium batteries have experienced decades of development, such as the birth of lithium-ion batteries, lithium metal batteries and other types of lithium batteries. However, due to the characteristics of lithium batteries, they still face problems such as low energy density, lithium dendrite growth, reduced Coulomb cycle efficiency, and reversible decrease in capacity. These problems seriously affect the stability and safety of lithium batteries. Therefore, the research has focused on nanotechnology, which brings a good solution to these problems due to the properties of nanoparticles on the microscopic scale. This research summarises the application of nanotechnology in the development of lithium batteries by data analysis, and outlines the current mainstream research directions in several aspects for different types of batteries.
