Alkali ions pre-intercalated layered vanadium oxide nanowires for stable magnesium ions storage

Owing to the high energy density, high security and low price, rechargeable magnesium batteries (RMBs) are promising candidate for the next generation of high-performance batteries. However, the development of cathode materials for RMBs is hindered by the intensive polarization of Mg2+, which tends to destroy the stability of crystal structure and results in the degradation of batteries. Pre-intercalating the different alkali ions in crystal...
