<ul><li>Solid-state lithium batteries are considered safer and more powerful than lithium-ion batteries but face longevity issues due to tiny cracks and stress in the anode.</li><li>Metal fatigue is a key problem in solid-state lithium batteries, where repeated expansion and contraction of the anode during charging and discharging lead to cracks and microvoids.</li><li>These cracks create weak spots allowing dendrites to form, which can cause short circuits and battery failure.</li><li>Researchers have identified the Coffin-Manson law governing the battery materials' damage, providing a starting point to develop new materials or structures that could potentially extend the lifespan of solid-state lithium batteries.</li></ul>
