Interestingly, beyond the capacity fading, high-rate lithiation-induced reactivation can occur for the hollow sphere metal oxide electrodes in which lithiation-induced mechanical degradation can ...

Ryan North claims that if you make a hollow metal sphere big enough, you can turn it into a secret floating base to use while you try to take over the world. Or maybe you just want to hang out ...

The hollow-sphere structure employed in our study enabled the PPy to elastically deform and recover upon the application and release of external pressure (as shown in the schematic illustration in ...
