Microporous polymeric coatings for Li-ion battery electrodes

Lithium-ion batteries (LIBs) are commonly used for electric cars and portable electronic devices. In order to make these devices cheaper, lighter and more accessible, high capacity LIBs are needed. Lithium or silicon are ideal materials for LIBs due to their high specific capacity. However, they cannot be used to substitute the graphite anode in the current commercial LIBs due to the stability issue related to the lithium dendrites growth and the extreme volume change. Herein, polymers of intrinsic microporosity (PIMs) have been suggested as a potential solution to suppress the problems associated with the new anode materials. Different types of PIMs will be synthesised and used as a protective layer for Li metal anode to facilitate uniform deposition of Li metal, and as a binder for Si anode to put the Si-based materials together.
