A lithium-air battery and gas handling system demonstrator (2023)
Journal Article

The lithium-air (Li-air) battery offers one of the highest practical specific energy densities of any battery system at >400 W h kgsystem−1. The practical cell is expected to operate in air, which is flowed into the positive porous electrode where it... Read More about A lithium-air battery and gas handling system demonstrator.

Why charging Li–air batteries with current low-voltage mediators is slow and singlet oxygen does not explain degradation (2023)
Journal Article

Although Li–air rechargeable batteries offer higher energy densities than lithium-ion batteries, the insulating Li2O2 formed during discharge hinders rapid, efficient re-charging. Redox mediators are used to facilitate Li2O2 oxidation; however, fast...

Hydroperoxide-Mediated Degradation of Acetonitrile in the Lithium–Air Battery (2023)
Journal Article

Understanding and eliminating degradation of the electrolyte solution is arguably the major challenge in the development of high energy density lithium–air batteries. The use of acetonitrile provides cycle stability comparable to current state-of-the... Read More about Hydroperoxide-Mediated Degradation of Acetonitrile in the Lithium–Air Battery.

Voltammetric Evidence of Proton Transport through the Sidewalls of Single-Walled Carbon Nanotubes (2023)
Journal Article

Understanding ion transport in solid materials is crucial in the design of electrochemical devices. Of particular interest in recent years is the study of ion transport across 2-dimensional, atomically thin crystals. In this contribution, we describe...

Self-Assembled Surfactant-Polyoxovanadate Soft Materials as Tuneable Vanadium Oxide Cathode Precursors for Lithium-Ion Batteries (2023)
Journal Article

The mixing of [V10O28]6− decavanadate anions with a dicationic gemini surfactant (gem) leads to the spontaneous self-assembly of surfactant-templated nanostructured arrays of decavanadate clusters. Calcination of the material under air yields highly...

Enflurane Additive for Sodium Negative Electrodes (2022)
Journal Article

Development of sodium anodes, both hard carbon (HC) and metallic, is dependent on the discovery of electrolyte formations and additives able to stabilize the interphase and support Na+ transport. Halogen salt additives are known to lower the energy b... Read More about Enflurane Additive for Sodium Negative Electrodes.

Competitive Oxygen Reduction Pathways to Superoxide and Peroxide during Sodium-Oxygen Battery Discharge (2022)
Journal Article

The sodium-air battery offers a sustainable, high-energy alternative to lithium-ion batteries. Discharge in the cell containing glyme-based electrolytes can lead to formation of large cubic NaO2 particles via a solution-precipitation mechanism. While...

Singlet oxygen and dioxygen bond cleavage in the aprotic lithium-oxygen battery (2022)
Journal Article

Investigation of lithium-oxygen cells on discharge using a mixture of 16O16O and 18O18O gases, showed that O–O bond cleavage occurs during disproportionation of LiO2 to O2 and Li2O2, detected by the presence of isotopic 16O18O. The formation of singl... Read More about Singlet oxygen and dioxygen bond cleavage in the aprotic lithium-oxygen battery.
