Scientists 'stretch' li-ion batteries storage capacity, lifespan
Standard charging/discharging cycles cause electrodes to expand and compress, creating microcracks that degrade capacity over time. Recent breakthroughs in 2024 and 2026 have introduced
Researchers from the Shanghai Academy of Spaceflight Technology recently developed an electrolyte that could potentially double the range of existing batteries by improving ion conduction and low-temperature performance. By pre-stretching intercalation electrodes
Scientists at the University of Southern California (USC) have developed a method to physically stretch battery electrodes during manufacturing to increase their resilience. researchers can regulate "phase transformation voltages
Recent breakthroughs in 2024 and 2026 have introduced batteries that can physically expand like rubber without losing performance.
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.
By pre-stretching intercalation electrodes, researchers can regulate "phase transformation voltages," making the materials less susceptible to fracturing.
