Commercial batteries have been largely applied in mobile electronics, electric vehicles, and scalable energy storage systems. However, thermal runaway of still obstructs the reliability equipment. Considering this, building upon recent investigations safety, commercially available organogel fiber-based implantable sensors developed through 3D printing technology for first operando monitoring cell temperature. The printed fibers present excellent superelasticity because internal supramolecular cross-linking. High temperature sensitivity (−39.84% °C–1/–1.557% °C–1) within a wide range (−15 to 80 °C) is achieved, corresponding mechanism clarified based on situ temperature-dependent Raman technology. Furthermore, taking pouch as an example, combined with finite element analysis, real-time observation system successfully demonstrated implanted sensor wireless Bluetooth transmission. This enlightening approach paves way achieving safety smart warnings various

Lithium-ion batteries (LIBs) are currently the predominant energy storage power source. However, urgent issues of enhancing electrochemical performance, prolonging lifetime, preventing thermal runaway-caused fires, and intelligent application obstacles to their applications. Herein, bio-inspired electrodes owning spatiotemporal management self-healing, fast ion transport, fire-extinguishing, thermoresponsive switching, recycling, flexibility overviewed comprehensively, showing great promising potentials in practical due significantly enhanced durability safety LIBs. Taking advantage self-healing core-shell structures, binders, capsules, or liquid metal alloys, these can maintain mechanical integrity during lithiation-delithiation cycling. After incorporation fire-extinguishing current collectors, flame retardants be released spatiotemporally runaway ensure safety. Thermoresponsive switching also constructed though adding thermally responsive components, which rapidly switch LIB off under abnormal conditions resume functions quickly when normal operating return. Finally, challenges electrode designs presented optimize It is anticipated that proposed with will not only promote industrial application, but strengthen fundamental research bionics storage.

Lithium-ion batteries (LIBs) have become one of the most competitive energy storage technologies. However, “thermal runaway” LIBs leads to serious safety issues. Early warning is a prerequisite for widely applications power battery and large-scale systems. As reported, hydrogen (H2) could be generated due reaction lithium metal polymers inside battery. The generation H2 some time earlier than runaway”. Therefore, rapid detection trace effective method early LIBs. Resistive sensors attracted attention in recent years. In addition, they placed LIB package initial detection. Here, we overview key advances resistive room temperature (RT) sensors, explore possible LIB.
