Summary: Routine electrolyte additives are not effective enough for uniform zinc (Zn) deposition. Based on underpotential deposition (UPD), an escort effect of electrolyte additives for uniform Zn deposition at the atomic level is proposed. With nickel ion (Ni2+) additives, metallic Ni deposits preferentially and triggers the UPD of Zn on Ni, facilitating firm nucleation and uniform growth of Zn while suppressing side reactions. The optimized cell operates for over 900 h at 1 mA cm(-2), more than 4 times longer than the blank one, indicating the significance of this work.

Summary: In this study, a facile manufacturing process is used to fabricate Zn-MnO2 microbatteries with a 3D macroporous microelectrode, which exhibit easy integration, mass customization, and superior electrochemical performance. The microbatteries achieve ultrahigh capacity and outstanding areal energy density due to the high electron/ion transport path and high mass-loading of the PEDOT-MnO2 film. Additionally, a 3D macroporous PEDOT-MnO2 hybrid film is achieved, which improves the cycling performance without reducing areal capacity or hindering ion diffusion. Therefore, the PEDOT-MnO2//Zn microbatteries hold great potential as a next-generation component for self-powered microelectronic devices.

Summary: In this work, an ultrathin solid-state electrolyte (SSE) named LA-SSE was developed by combining a lipoic acid-assisted semi-interpenetrating polymer network and an ultrathin porous membrane. LA-SSE, with a thickness of only 10 μm, showed excellent mechanical properties to suppress lithium dendrite growth and favorable interfacial compatibility between the lithium anode and electrolyte. By using LA-SSE as the electrolyte, long-term cycling of over 3000 hours was achieved in a Li parallel to LA-SSE parallel to Li symmetric cell, and a LiFePO4 parallel to LA-SSE parallel to Li full battery exhibited stable operation over 200 cycles with a capacity retention of 84% at room temperature. This study provides a promising strategy for designing ultrathin SSEs with satisfactory mechanical properties, excellent interfacial compatibility, and safety for lithium-ion batteries.
