Южнокорейски учени създадоха нов електрод за литиево-серните батерии, като го покриха с ултратънка полимерна „кожа“. Решението е помогнало на батерията да работи стабилно след повече от хиляда цикъла на зареждане и разреждане. Екипът от Корейския университет разработи литиево-метален анод, използвайки пореста рамка от материала MXene, покрита с полимерен филм с дебелина само около 100 нанометра. Според Корейския университет, този слой действа като вид „изкуствена кожа“: той предотвратява проникването на електролита през повърхността на електрода, но позволява на литиевите йони да преминават. Това дава възможност на метала да се натрупва по-равномерно вътре в порестата структура и броят на нежеланите химични реакции се намалява.

Carbon nanotubes and MXene combine shielding, strength and thermal camouflage in a hair-thin film.

A research team led by Dr. Taehoon Kim of the Composites & Convergence Materials Research Division at the Korea Institute of Materials Science (KIMS), collaborated with research teams led by Dr. Seon Joon Kim and Dr. Jaewoo Kim of the Korea Institute of Science and Technology (KIST) to develop an ultrathin composite film that combines electromagnetic interference (EMI) shielding, infrared (IR) stealth and high mechanical strength.

Carbon nanotube fibers and MXene form an ultrathin, mechanically strong film that provides electromagnetic interference shielding while suppressing infrared emission.

MXenes are two-dimensional nanomaterials first synthesized at Drexel University in 2011. They have been recognized by the International Union of Pure and Applied Chemistry as an emerging technology with "true potential to transform our world." But their widespread use has thus far been limited by the complicated process required to produce them.
