    Using custom optics, the laser radiates a larger area on the copper foil coated with graphite paste. The interaction between the graphite particles and the light energy generates heat and the liquid evaporates.
    As startups and global transportation manufacturers continue to explore and make commitments to expand e-mobility, improving batteries ultimately takes center stage.

    Schematic illustration of light-induced ultrafast lattice response in 2D perovskites. An ultrashort laser pulse creates a high density of electron-hole plasma, which triggers a relaxation of the lattice distortion via reduced octahedral tilt.
    Thanks to ultrafast electron diffraction at SLAC National Lab, researchers captured a change of structural response in 2D perovskites: a relaxation of lattice distortion initiated...
