“…The EDS elements mapping confirms that lithiated‐Nafion with a thickness of ≈9 nm is evenly distributed as a coating on the surface of NCM particles ( Figure 5 i; Figures S25 and S26, Supporting Information). Both NCM and NCM@LN are of typical hexagonal α‐NaFeO 2 structure (Figure S27, Supporting Information), [ 61–64 ] indicating that the presence of the lithiated‐Nafion nanolayer does not have a substantial impact on the crystal phase of NCM.…”

Ultrathin all‐solid‐state electrolytes with an excellent Li+ transport behavior are highly desirable for developing high‐energy‐density solid‐state lithium metal batteries. However, how to balance the electrochemical performance and their mechanical properties remains a huge challenge. Herein, an ultrathin solid electrolyte membrane with a thickness of only 3 µm and a weight of 11.7 g m−2 is well constructed by integrating individual functionalized organic with inorganic modules. Impressively, the optimized hybrid electrolyte membrane shows a set of merits including a high room‐temperature ionic conductivity of 1.77 × 10−4 S cm−1, large Li+ transference number of 0.65, and strong mechanical strength (strength of 29 MPa, elongation of 95%), as well as negligible thermal shrink at 180 °C. The analysis results reveal that the lithium sulfonate‐functionalized mesoporous silica nanoparticles in the membrane play a crucial role in the selective transport of Li+ through anion trapping and cation exchange. The pouch full cell is further assembled with a high‐voltage NCM cathode and thin lithium anode, which exhibits excellent long‐term cycling stability, outstanding rate performance at room temperature, and high safety against abused conditions. The current work provides an innovative strategy for achieving lithium metal batteries with ultrathin all‐solid‐state electrolytes.

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

“…3,4 However, there are still several issues that need to be addressed before applying lithium metals to lithium metal batteries: (1) the extra irreversible reaction between lithium electrodes and organic electrolytes will produce a thick passivation film (SEI) on the surface of lithium electrodes, consume a large amount of lithium and electrolyte, and also increase impedance and reduce the cycle life. 5,6 (2) Uncontrolled growth of lithium dendrites in repeated plating/stripping results in the formation of “dead” lithium, which is easy to pierce the separator and cause an inner short circuit, bringing great safety hazards. (3) The volume and morphology changes of lithium metal batteries (LMBs) caused by repeated plating/stripping processes of lithium metal anodes affect their safety use.…”
