Extended Cycle Life in Lithium‐Ion Batteries through Lithium Supplementation from Li2C4O4@SiO2 Microcapsules

open access: yesBatteries &Supercaps, EarlyView.
The use of Li2C4O4@SiO2 microcapsules, in which Li2C4O4 serves as an additional source of lithium ions and the porous SiO2 shell shields direct contact between the active material and Li2C4O4, enables an additional supply of lithium ions in the battery cell.

Long‐Term Cycling Stability of Sodium/Sodium Ion Cells Probed by In Situ Solid‐State NMR Spectroscopy

open access: yesBatteries &Supercaps, EarlyView.
The suitability of 23Na in situ solid‐state nuclear magnetic resonance (NMR) spectroscopy for long‐term studies of sodium/sodium ion cells is tested. Using silicon carbonitride and hard carbon working electrodes, local structures are analyzed up to the point of capacity degradation and cell failure.

Effective pretreatment of wet microalgal biomass to enhance lipid extraction in biodiesel production

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract Biodiesel is a viable alternative to fossil fuels. Identifying and evaluating nonedible sources is essential to address ecological concerns and meet energy demands. Microalgae are effective for lipid production but their rigid cell walls hinder bioproduct release making the process energy‐intensive and costly.
