By pre-stretching intercalation electrodes, researchers can regulate "phase transformation voltages," making the materials less susceptible to fracturing.
Standard charging/discharging cycles cause electrodes to expand and compress, creating microcracks that degrade capacity over time. By pre-stretching intercalation electrodes
Broader research is "stretching" the capacity limits of Li-ion technology through material innovation: researchers can regulate "phase transformation voltages
Researchers have recently made significant breakthroughs in "stretching" lithium-ion batteries—both literally and metaphorically—to enhance their storage capacity, lifespan, and physical flexibility. By pre-stretching intercalation electrodes
This approach allows batteries to operate in a wider voltage window , which directly increases their efficient energy storage capacity and extends their overall lifespan. 2. Fully Stretchable Batteries for Wearables
