To address the major drawbacks of traditional lithium-ion batteries, researchers have suggested the creation of solid-state lithium-ion batteries (SSLIBs) as a viable panacea. In contrast to conventional lithium-ion batteries, which utilize polymer electrolytes or organic liquid, SSLIBs incorporate solid electrolytes of inorganic origin.
Achieving a rational structural design to optimize the stress distribution in silicon/carbon composites has been demonstrated as an effective approach.
