But, in a solid state battery, the ions on the surface of the silicon are constricted and undergo the dynamic process of lithiation to form lithium metal plating around the core of silicon. "In our design, lithium metal gets wrapped around the silicon particle, like a hard chocolate shell around a hazelnut core in a chocolate truffle," said Li.
Hard carbon, on the other hand, has a larger interlayer spacing and is therefore a more suitable host for Si-NPs in SIBs. In this manner, a composite of Si-NPs inside a matrix of hard carbon can provide a more reliable anode for SIBs. Although hard carbon is becoming a popular anode for SIBs, it has not been explored for the integration of Si-NPs.
