Solid‐state batteries (SSBs) are under development as high‐priority technologies for safe and energy‐dense next‐generation electrochemical energy storage systems operating over a wide temperature range. Solid‐state electrolytes (SSEs) exhibit high thermal stability and, in some cases, the ability to prevent dendrite growth through a physical barrier, and compatibility with the “holy grail” metallic...
The design and fabrication of a lithiophilic skeleton are highly important for constructing advanced Li metal anodes. In this work, a new lithiophilic skeleton is reported by planting metal sulfides (e.g., Ni3S2) on vertical graphene (VG) via a facile ultrafast Joule heating (UJH) method, which facilitates the homogeneous distribution of lithiophilic sites on carbon cloth (CC) supported VG substrate...
The design and fabrication of novel carbon hosts with high conductivity, accelerated electrochemical catalytic activities, and superior physical/chemical confinement on sulfur and its reaction intermediates polysulfides are essential for the construction of high‐performance C/S cathodes for lithium–sulfur batteries (LSBs). In this work, a novel biofermentation coupled gel composite assembly technology...
All‐solid‐state lithium metal batteries (LMBs) are regarded as one of the most viable energy storage devices and their comprehensive properties are mainly controlled by solid electrolytes and interface compatibility. This work proposes an advanced poly(vinylidene fluoride‐hexafluoropropylene) based gel polymer electrolyte (AP‐GPEs) via functional superposition strategy, which involves incorporating...
Solid‐state lithium–sulfur batteries (SSLSBs) have attracted tremendous research interest due to their large theoretical energy density and high safety, which are highly important indicators for the development of next‐generation energy storage devices. Particularly, safety and “shuttle effect” issues originating from volatile and flammable liquid organic electrolytes can be fully mitigated by switching...
Nickel sulfides with high theoretical capacitance have aroused tremendous attention for next‐generation supercapacitors. Unfortunately, the structural durability of nickel sulfides is insufficient to support the long‐term working situation. Herein, Ni3S4‐x hollow microspheres with sulfur vacancies (Ni3S4‐x HMs) are constructed by a liquid‐phase anion exchange process using the Ni‐MOF as the precursor...
Tailored construction of advanced flexible supercapacitors (SCs) is of great importance to the development of high‐performance wearable modern electronics. Herein, a facile combined wet chemical method to fabricate novel mesoporous vanadium nitride (VN) composite arrays coupled with poly(3,4‐ethylenedioxythiophene) (PEDOT) as flexible electrodes for all‐solid‐state SCs is reported. The mesoporous...
