Standard charging/discharging cycles cause electrodes to expand and compress, creating microcracks that degrade capacity over time.
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 Fully Stretchable Batteries for Wearables Scientists at the
Scientists at the University of Southern California (USC) have developed a method to physically stretch battery electrodes during manufacturing to increase their resilience. Other designs can withstand a 1200% stretch and
By pre-stretching intercalation electrodes, researchers can regulate "phase transformation voltages," making the materials less susceptible to fracturing. researchers can regulate "phase transformation voltages
Scientists 'stretch' li-ion batteries storage capacity, lifespan
Some prototypes feature electrolyte layers that can stretch up to 5000% while maintaining stable capacity over 70 cycles. Other designs can withstand a 1200% stretch and still power devices like LEDs.
Incorporating silicon (often mixed with carbon nanotubes) is a key strategy for 2026 to "stretch" capacity, as silicon can store significantly more energy than graphite. New "Vertically Integrated Silicon-Carbon Nanotube" (VISiCNT) structures help prevent the typical cracking associated with silicon expansion.
