Lithium metal battery (LMB) possessing a high theoretical capacity is promising candidate of advanced energy storage devices. However, its safety and stability are challenged by lithium dendrites the leakage liquid electrolyte. Here, self-enhancing gel polymer electrolyte (GPE) created in situ polymerizing 1,3-dioxolane (DOL) nanofibrous skeleton for enabling safe LMB. The nanofiber membrane possesses better affinity with poly-DOL (PDOL) than commercial separator constructing homogeneous GPE...

Abstract The energy storage performance of sodium‐ion batteries has been greatly improved by pairing ether‐based electrolytes with high‐capacity alloy‐type anodes. However, the origin this improvement a unique electrode/electrolyte interface yet to be explored. To understand such results, herein, deterministic and distinct interfacial chemistries solid electrolyte interphase (SEI) layers in both ether‐ ester‐based are described, as verified post mortem, in‐depth X‐ray photoelectron...

Abstract All‐solid‐state Li metal batteries (ASSLMBs) using inorganic solid‐state electrolytes (ISEs) are considered promising energy storage technologies owing to their intrinsic safety and high density. Nevertheless, one critical challenge confronting ASSLMBs is the inability of ISEs prevent dendrite growth, which has not yet been fully addressed. Herein, general design principles artificial solid electrolyte interphases (ASEI) for suppressing dendrites in proposed by systematically...
The effects of polyaniline (PANI) with different polymerization times on the film-forming and thermoelectric properties as well performance SWCNTs/PANI composites were systematically investigated in this study. It was found that flexibility PANI films improved increase time. We showed a super high conductivity ∼4000 S cm-1 can be achieved for composite film, which is highest value system at present. Both electrical power factor by an order magnitude than pure far exceed theoretical mixture...
Nanostructuring strategies have immensely improved energy storage performance for Li ion batteries. However, the consequent low tap density and severe side reaction caused by excessive specific surface area make it difficult nanomaterials to exhibit satisfactory in their practical applications. Herein, inspired structural characteristics of egg cartons, a rational nanomicro structure was designed address these problems. Specifically, compact micron-size 2D dimpled carbon frameworks (cartons)...

Poly (vinylidene fluoride) (PVDF)-based polymer electrolytes (PEs) with good electrochemical performance and processability as well low-cost advantage, have great potential applications in solid-state lithium (Li) metal batteries (SSLMBs). PVDF-based PEs are generally produced by employing a solution-casting approach N,N-dimethylformamide (DMF) the solvent, accompanied formation of [DMF-Li+] complex, which facilitates Li-ion transport. However, residual DMF can react continuously metal,...
