AI Customer ServiceOne of the key components of a lithium-ion battery is separator film. It can help to prevent short-circuiting and stop thermal runaways with its special thermal shutdown properties, all while still facilitating the flow of charged ions. The safety and efficiency of separator film can be improved by coating it with materials such as ceramic.
According to Sepion, its unique property sets this membrane apart – it allows the unrestricted flow of lithium ions while effectively obstructing the passage of electrolyte solvents. As a result, lithium metal batteries using these separator coatings have a higher energy storage capacity compared to current Li-ion batteries.
In this study, a novel method of applying a Lithium titanate (LTO) active coating on the separator of Li-ion batteries is proposed. The LTO active coating can participate in electrochemical reactions and provide additional capacity.
Lithium-ion batteries (LIBs) require separators with high performance and safety to meet the increasing demands for energy storage applications. Coating electrochemically inert ceramic materials on conventional polyolefin separators can enhance stability but comes at the cost of increased weight and decreased capacity of the battery.
In addition, the LTO coating layer can enhance the Li-ion transport and unify Li-ion flux, preventing the growth of lithium dendrite. This method offers a simple and effective way to enhance the performance and safety of LIBs by using an active coating on the separator.
Among the key components (anode, cathode, separator, electrolyte, current collection) of LIBs, separator is a crucial one to guarantee safety property by physically isolating the cathode and anode, and maintain good electrochemical performance by providing lithium ions free flow microporous structure [, , , ].
