摘要
Structural batteries are projected to substantially increase system-level specific energy. By storing energy and bearing mechanical loads, structural batteries reduce the amount of conventional structural materials required by devices. Two approaches to enable this concept have emerged. One emphasizes monofunctional materials with decoupled mechanical and electrochemical functions. The other focuses on multifunctional materials with coupled functions. By using a meta-analysis on reported structural batteries and the flexural-rigidity equation, we show that decoupled structural batteries generally outperform coupled versions. © 2020 Elsevier Inc.
