Elucidation of structural property in Li-ion batteries that deliver ultra-fast charging: Improving Li-ion batteries by coating their cathode with BaTiO3 nanodots

Scientists have found a way of greatly improving the performance of LiCoO2 cathodes in Li-ion batteries by decorating them with BaTiO3 nanodots. Most importantly, they elucidated the mechanism behind the measured results, concluding that the BaTiO3 nanodots create a special interface through which Li ions can circulate easily, even at very high charge/discharge rates.
