Abstract—This study provides a comprehensive overview of recent advances in electrochemical energy storage, including Na+-ion, metal-ion, and metal-air batteries, alongside innovations in electrode engineering, electrolytes, and solid-electrolyte interphase control.. Using electric energy on all scales is practically impossible without devices for storing and converting this energy into other storable forms. This applies to many mobile and portable applications, grid-related stationary applications, and the growing integration of renewable energies.. Given the escalating demand for wearable electronics, there is an urgent need to explore cost-effective and environmentally friendly flexible energy storage devices with exceptional electrochemical properties. It also explores the integration.
