Mimicking Capacity Degradation in a Lithium Ion Battery Anode in Cells With a Li Metal Electrode: A Perspective on Advantages

Advanced Energy & Sustainability Research
The lifetime of Li‐ion batteries (LIB) depends on the amount of Li ions and electrons (= active Li), definingLi inventory and cell capacity and can be limited by active Li loss (ALL) at the negative electrode (= anode), e.g., via electrolyte reduction ...

Demonstrating Vibrational Current Generation With a Self‐Assembled Bioelectret

Advanced Functional Materials, EarlyView.
Vacuum‐deposited films of the plant‐derived molecule, Baicalein, form a self‐assembled bioelectret exhibiting spontaneous orientation polarization and a giant surface potential. The films induce alternating current during the vibration of a movable electrode without charging treatments. Hydrocarbon protection enhances the air stability of the Baicalein

Enhanced lithium host performance of multi-walled carbon nanotubes through acidic functionalization for lithium–sulfur batteries

Heliyon
Carbon nanotubes (CNTs) have been explored as a potential cathode material for lithium-sulfur (Li–S) batteries owing to their unique structure. However, traditional CNTs exhibit poor dispersion properties when preparing electrodes.
