      abstract     = {Here in this work, we report on micro-Raman spectroscopy
                      investigations performed on freestanding Ni-rich NCM
                      (LixNi0.83Co0.11Mn0.06O2) microcrystals transferred to
                      flexible polyethylene terephthalate (PET) host substrates.
                      This technological procedure introduces a first building
                      block for future on-chip-integrated micro-accumulators for
                      applications in flexible optoelectronics, sensors,
                      microbiology, and human medicine. An after-synthesis thermal
                      treatment was used to help improve the material homogeneity
                      and perfection of the cathode material. To this end, a local
                      laser micro-annealing process was applied to the
                      freestanding Ni-rich NCM microcrystals. The thermally
                      initialized structural processes in the singular
                      micro-cathode units were characterized and determined by
                      micro-Raman spectroscopy. Micro-Raman mapping images
                      revealed the evolution of a recrystallization process after
                      the local annealing procedure. Furthermore, laser
                      micro-annealing led to the suppression of the pristine
                      “polycrystalline morphology” of the investigated
                      micro-cathode regions. Besides the dominant characteristic
                      Raman mode at ~1085 cm−1, most likely ascribed to lithium
                      carbonate, metal oxides with Raman modes around ~550 cm−1
                      were identified. This highly efficient transfer and
                      integration technology represents a basic building block
                      towards micrometer-sized accumulators for a large range of
                      emerging applications.},
