Ti3C2Tx/Ni5P4/NiP2 Double‐Heterojunction Anodes With Fluoride‐Free Interfacial Engineering for High‐Rate and Ultrastable Lithium Storage
Transition metal phosphides (TMPs) are promising lithium‐ion battery anodes but are hindered by severe volume expansion and poor cycling stability. To address these challenges, we report a fluoride‐free strategy combining Lewis acidic molten salt etching and in situ phosphorization to grow biphasic Ni5P4/NiP2 nanoparti...
