Lithium-ion 'traffic jams' ease with additive that helps unlock energy in thicker battery electrodes
Researchers in South Korea have developed a new cathode additive using graphitic carbon nitride to improve the performance of thick-film lithium-ion batteries. This technology helps overcome 'ion traffic jams,' allowing for higher energy density in batteries for electric vehicles.
Why it matters
Advancements in battery electrode technology are critical for increasing the range and efficiency of electric vehicles, accelerating the transition to sustainable transport.

Credit: Korea Research Institute of Chemical Technology (KRICT) To develop batteries that last longer on a single charge, more energy must be stored without increasing their size or weight. A research team led by Dr. San Moon and Dr. Jungdon Suk at the Korea Research Institute of Chemical Technology (KRICT) has developed a dry thick-film cathode technology by incorporating graphitic carbon nitride (g-C 3 N 4 ) as a cathode additive for the first time.
