We have analysed the Li nucleation and growth in a 90-µm-thick LNI–CNT interlayer and validated the interlayer design principle (Supplementary Table 5). To enhance the energy den.Solid-state batteries can use metallic lithium for the anode and oxides or sulfides for the cathode, increasing energy density1. The solid electrolyte acts as an ideal separator that allows only lithium ions to pass through. The solid-state battery developed by Harvard researchers uses a lithium metal anode as opposed to a graphite anode, which has ten times the capacity of commercial graphite anodes and uses micron-sized silicon particles to stop dendrites forming on the anode2. However, dendrites can form on the surface of the lithium metal anode, which can cause the battery to short or even catch fire3. Solid-state lithium batteries can utilize any anode material, but there is an implicit assumption that they will utilize lithium-metal anodes4.
