Metal hydride reaction
WebVandaag · Cai W. et al. [23] found that the addition of carbon nanotubes prevents the nucleation of the metal from the hydride as a result of nanoconfinement. On the contrary, this leads to a decrease in the efficiency of the desorption kinetics. In the case of the SWCNTs – metal hydrides systems, these issues have received only limited attention. Web23 mrt. 2024 · Project 2 : Hydrides have outstanding properties as both negative electrodes and solid electrolytes for Li-ion batteries. Metal hydrides can operate as anodes through the conversion reaction MHx + xLi <-> M + xLiH leading to high gravimetric (1000-2000 mAh/g) and volumetric (2000-4000 mAh/cm3) capacities with a typical potential < 0.6 V [1].
