Another severe problem caused by expansion is the formation of unstable solid‐electrolyte interphase (SEI) layer, . 159 The SiO x layer was generated from the low‐cost, sol‐gel reaction of triethoxy silane. There are obviously observed SiO x 8D,E).

Herein, we report a novel glucose-responsive insulin-release nanosystem through an enzyme–polymer layer-by-layer coating strategy on silica vesicles loaded with insulin. With a choice of polyethylenimine with prioritized proton binding capability and glucose specific enzymes in the coating layer, the insulin-release threshold can be adjusted in a desired glucose concentration range 5–20 mM

An Artificial Polyacrylonitrile Coating Layer Confining Zinc

Aqueous rechargeable zinc‐metal‐based batteries are an attractive alternative to lithium‐ion batteries for grid‐scale energy‐storage systems because of their high specific capacity, low cost, eco‐friendliness, and nonflammability. However, uncontrollable zinc dendrite

Modification of Ni

Our results show that Al2O3 coating improved the NMC cycling performance by 40% and the NCA cycling performance by 34% at 1C/₋1C with respectively 4.35V and 4.4V UCV in 2Ah pouch cells. High resolution TEM/SAED structural characterization revealed that Al 2 O 3 coatings prevented surface-initiated layered-to-spinel phase transitions in coated materials which were prevalent in uncoated

Sodium metal battery (SMB, NMB) anodes can become dendritic due to an electrochemically unstable native Na-based solid electrolyte interphase (SEI). Herein Li-ion activated tin sulfide graphene nanocomposite membrane (A-SnS–G) is employed as an artificial SEI layer, allowing cyclability of record-thin 100 μm Na metal foils.

Solid electrolyte interphases for high

Electrochemical cells based on aluminum (Al) are of long-standing interest because Al is earth abundant, low cost, and chemically inert. The trivalent Al3+ ions also offer among the highest volume-specific charge storage capacities (8040 mAh cm−3), approximately four times larger than achievable for Li metal anodes. Rapid and irreversible formation of a high-electrical bandgap passivating

Design Principles of Artificial Solid Electrolyte

Global energy demands drive both academic and industrial interest in lithium-metal batteries, demanding the development of a stable artificial solid electrolyte interphase to protect the lithium-metal anode. Three critical design principles and selected examples of artificial solid electrolyte interphases are explored in this review.

We employed atomic layer deposition (ALD) for conformal coating of two types of overlayers (In 2 O 3 and TiN), i.e., oxide and nitride thin film, on an electrospun carbon nanopaper (CNp) membrane. The LOB cell with In 2 O 3 -coated CNp exhibited much enhanced cycling performance (over 140 cycles) compared with pristine CNp and TiN-coated CNp as control samples (less than 60 cycles for both

Coulombic efficiency especially in the first cycle, cycling stability, and high-rate performance are crucial factors for commercial Li-ion batteries (LIBs). To improve them, in this work, Al2O3-coated natural graphite powder was obtained through a low-cost and facile sol–gel method. Based on a comparison of various coated amounts, 0.5 mol % Al(NO3)3 (vs mole of graphite) could bring about a

Artificial Cathode

Silver vanadates (SVOs) have been widely investigated as cathode materials for high-performance lithium-ion batteries (LIBs). However, similar to most vanadium-based materials, SVOs suffer from structural collapse/amorphization and vanadium dissolution from the electrode into the electrolyte during the Li insertion and extraction process, causing poor electrochemical performance in LIBs. We
