Standard charging/discharging cycles cause electrodes to expand and compress, creating microcracks that degrade capacity over time.
A new solid stretchy battery design demonstrated 6x higher average charge capacity at fast-charging rates compared to traditional liquid-electrolyte versions.
By pre-stretching intercalation electrodes, researchers can regulate "phase transformation voltages," making the materials less susceptible to fracturing.
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.
