In recent years, there has been a notable surge in efforts aimed at advancing lithium-ion batteries, crucial for electric vehicles, stationary storage technologies, and portable electronics. The lifespan of these batteries, particularly concerning capacity fade, hinges largely on electrode degradation and the deactivation of active materials. Additionally, a pivotal factor impacting both battery lifespan and […]

Parallel connected battery modules are a necessary component of large battery packs to increase the overall pack capacity. Unlike series connected cell systems, conventional parallel battery modules have a sparse sensing arrangement such that the battery management system (BMS) does not measure individual cell currents and temperatures. In this arrangement, single cell failures and current […]

The overwhelming majority of lithium-ion batteries currently in use feature a graphite anode, which is approaching its maximum theoretical capacity. Lithium metal batteries are regarded as pivotal enablers for the forthcoming generation of lithium-ion technology, largely due to their superior energy density. Indeed, lithium (Li) metal has the lowest reduction potential (-3.04 V vs. std […]

Lithium-sulfur (Li-S) cells have the potential to provide high gravimetric density energy storage, but currently suffer from rapid capacity degradation due to redistribution of the electrochemically active material during cycling. Research to address this challenge typically aims to synthesise cathodes with homogeneously dispersed sulfur particles, seeking uniform current density and discharge product deposition to enable […]

Approximately four billion discarded tires end up in landfills each year due to inadequate recycling, contributing to severe environmental concerns. Transforming waste tires into carbon powder for alkali-ion battery anodes presents a promising recycling solution, yet heavy metals and unwanted elements hinder electrochemical performance. Conventional purification methods rely on harsh chemicals like concentrated sulfuric acid […]
