In this work, planarization growth by hydride vapor phase epitaxy (HVPE) is studied as a method of enabling the direct use of spalled substrates without polishing. A 24%-efficient solar cell is achieved after in situ growth planarization of 3-µm-tall facets with equivalent open-circuit voltage compared to a device grown on a traditional planar substrate....

The integration of porous high-loading electrodes and in-situ polymerized electrolytes is a facile and effective approach for commercially large-scale production and application in high-energy-density and safe lithium-ion batteries, which improves interfacial contact between electrode and electrolyte, provides a homogeneous distribution of Li-ion...

An overview of strategies of preparation of fiber shaped battery and corresponding integration techniques and patterns are reported, which can significantly affect both the electrochemical and mechanical performances. This review aims to address pivotal questions regarding design of FSBs and provides an overview of relationship between traditional...

The electrocatalytic properties of multi-metal materials are determined by electronic and geometric parameters, which are intricately intertwined. This research investigates the interplay between these parameters, using the quaternary Pd─Ag─Cu─Fe thin-film system as a platform. The established correlation between valence electron density and catalytic...

By combining the density functional theory calculation and experimental results, the charge transfer source and spin polarization engineering of the active center of pyridinic-N are revealed and applied to low-temperature quasi-solid Zn–air batteries. Abstract The oxygen reduction reaction (ORR) is a crucial cathode reaction for developing...

A cathode additive, interlayer expanded zirconium hydrogen phosphate (EI-ZrP), is employed to confine polyiodides and provide multiple channels for zinc ions transport. This additive significantly improves the rate and long-cycle performance of aqueous Zn-I2 batteries. For practical application, a Zn-I2 paper battery incorporating the EI-ZrP is integrated...
