Highlights with ‘batteries’

A ReaxFF force field for sodium intrusion in graphitic cathodes

A new force field has been developed to study sodium interactions in carbonaceous materials, using the MCFF Optimizer on ADF energies and MDC-q charges. With this force field important processes in sodium ion batteries and aluminium electrolysis...

ReaxFF molecular dynamics simulations on lithium sulfur batteries

Understanding of the structural, and kinetic behavior of the sulfur cathode materials are crucial for designing high performance Li-S batteries. In a recent study, ReaxFF molecular dynamics simulations has been utilized to study sulfur cathode...

ReaxFF: Teflon coating reduces Li-S battery electrolyte decomposition

Lithium released from the anode is a highly exothermic process in lithium-sulfur batteries, and as such can lead to reactions with the electrolyte. In a recent ReaxFF study, the lithium discharge from a single-walled carbon...

Relativistic effects up the voltage in batteries

In Early 2011, researchers Rajeev Ahuja, Andreas Blomqvist and Peter Larsson at Uppsala University along with Pekka Pyykkö and Patryk Zaleski-Ejgierd at the University of Helsinki published the results of an extensive computational study on...
