    A powerful new material developed by the team of Northwestern University chemists could one day speed up the charging process of electric cars and help increase their driving range.
    An electric car currently relies on a complex interplay of both batteries and supercapacitors to provide the energy it needs to go places, but that could change.
    According to scientists, this material combines the best of both worlds -- the ability to store large amounts of electrical energy or charge, like a battery, and the ability to charge and discharge rapidly, like a supercapacitor.
    Research team have combined a COF -- a strong, stiff polymer with an abundance of tiny pores suitable for storing energy -- with a very conductive material to create the first modified redox-active COF that closes the gap with other older porous carbon-based electrodes.
    But, while COFs are beautiful structures with a lot of promise, their conductivity is limited. By modifying them -- by adding the attribute they lack -- COFs could be used in a practical way.
    And modified COFs are commercially attractive: COFs are made of inexpensive, readily available materials, while carbon-based materials are expensive to process and mass-produce.
