Grating voltage damages Li-ion batteries

Lithium-ion battery performance degrades over time, but the underlying causes are not fully understood. Analysis of lithium- and manganese-rich cathodes now reveals how the lattice of atoms in these materials is strained, releasing oxygen…

Lithium-ion batteries that last longer in extreme cold

When temperatures drop below freezing, mobile phones often need recharging, and electric cars have shorter driving ranges. This is because the anodes of their lithium-ion batteries become sluggish, hold less charge and drain energy quickly.…

The life span of solid lithium batteries is extended

Researchers have successfully increased the life and stability of solid-state lithium-ion batteries, creating a viable approach for future widespread use.Person holding a lithium battery cell with an extended life showing where the ion…
