License of technology
IMDEA Materials has designed and synthesized metal oxide cathodes for Mg batteries. Superior intercalation of Mg-ions results in the high energy density. Cathodes of high capacity (up to 250 mAh/g) and ultralong life (˃3000 cycles).
In order to overcome the energy density and power density limitations of Mg batteries, we have designed and synthesized nanostructured metal oxide cathodes. Mg-ion storage in this case follows a pseudocapacitive mechanism. Diffusion independent nature of pseudocapacitive mechanism enables ultrafast charging (high power density) of the Mg battery.
Advantages and innovations
Superior intercalation of Mg-ions results in the high energy density. Cathodes of high capacity (up to 250 mAh/g) and ultralong life (˃3000 cycles) can be engineered and synthesized through this method. The strategy of pseudocapacitive Mg-ion storage can be extended for numerous metal oxide based cathodes for exceptional Mg-ion storage.
