Rechargeable batteries play a critical role in the energy storage field, due to their reliable performance and minimal maintenance. Currently, lithium-ion batteries represent the state-of-the-art technology; however, they suffer from moderate energy density, safety concerns, and limited lithium resources, which concurrently restrict their large-scale applications. To tackle these challenges, we integrate the knowledge of chemical bonding, intercalation reactions, material sciences, and electrochemistry to develop next-generation batteries for energy storage. The research focus will be devoted to solid-state batteries with higher energy density, aqueous batteries for higher safety, and post-lithium batteries (Na, K, H, Zn, etc.) for more sustainability.
