A greyscale erosion algorithm for tomography (GREAT) to rapidly detect battery particle defects

open access: yesnpj Materials Degradation, 2022
Particle micro-cracking is a major source of performance loss within lithium-ion batteries, however early detection before full particle fracture is highly challenging, requiring time consuming high-resolution imaging with poor statistics.

Calcium-tin alloys as anodes for rechargeable non-aqueous calcium-ion batteries at room temperature

open access: yesNature Communications, 2022
The key challenge for rechargeable Ca batteries originates from the severe passivation of the calcium metal anode in electrolyte solutions. Here, the authors demonstrate the feasibility and elucidate the electrochemical properties of calcium-tin (Ca–Sn ...

Nanocatalyzed PtNi Alloy Intact @3D Graphite Felt as an Effective Electrode for Super Power Redox Flow Battery

open access: yesAdvanced Materials Interfaces, 2023
A zinc‐bromine redox flow battery (RFB) is highly suitable for high‐energy storage due to its decoupled energy and power generation. However, the poor kinetics and poor reversible behavior of Br2/Br− redox activity are some of the significant barriers ...

Electrochemical Gating in Scanning Electrochemical Microscopy [PDF]

open access: yesThe Journal of Physical Chemistry C, 2008
We demonstrate that scanning electrochemical microscopy (SECM) can be used to determine the conductivity of nanoparticle assemblies as a function of assembly potential. In contrast to conventional electron transport measurements, this method is unique in that electrical connection to the film is not required.

Electrochemical Deposition of Nanomaterials for Electrochemical Sensing [PDF]

open access: yesSensors, 2019
The most commonly used methods to electrodeposit nanomaterials on conductive supports or to obtain electrosynthesis nanomaterials are described. Au, layered double hydroxides (LDHs), metal oxides, and polymers are the classes of compounds taken into account.

Analysis of the changes in quality and characteristics of hot air drying of Xinjiang jujube (Zizyphus jujuba Mill. cv. Junzao) following a delayed harvest

open access: yesScientific Reports, 2023
Dry processing is ineffective in preserving fresh jujubes (Zizyphus jujuba Mill.), contributing largely to the delayed jujube harvest in Xinjiang. However, no studies have evaluated the impact of delayed harvest periods on processing quality.

Trace Amounts of Triple-Functional Additives Enable Reversible Aqueous Zinc-Ion Batteries from a Comprehensive Perspective

open access: yesNano-Micro Letters, 2023
Highlights A triple functional additive with a trace amount (1 mM) was proposed to protect Zn anodes. The additive lowers the hydrogen evolution reaction potential, encourages the formation of an in situ solid electrolyte interphase and shields the “tip ...
