Interfacial friction enabling ≤ 20 μm thin free-standing lithium strips for lithium metal batteries [PDF]

Nature Communications, 2023
A practical high-specific-energy Li metal battery requires thin (≤20 μm) and free-standing Li metal anodes, but the low melting point and strong diffusion creep of lithium metal impede their scalable processing towards thin-thickness and free-standing ...
