An effective strategy to address these issues is optimizing the separator to regulate ion transport and trap the lost active component. Herein, a crosslinked gelatin nonwoven (CGN) separator is elaborately fabricated through electrospinning and <em>in-situ</em> vapor phase crosslinking process to manipulate the dual electrode interface. Benefitting from the characteristic composition of gelatin, and porous structure of electrospun nonwoven, the CGN separator exhibits excellent interface wettability and low interface resistance, featuring a high Li<sup>+</sup> transference number of 0.70 and high ionic conductivity of 3.75 mS/cm. As expected, the symmetrical Li/Li cells present stable cycling behavior for 1900 h at 0.5 mA/cm<sup>2</sup> with low overpotential of 20 mV. The optimized LiMn<sub>2</sub>O<sub>4</sub>/Li cells deliver high reversible capacity of 103 mAh/g as well as high capacity-retention ratio of 83.7 % after 100 cycles at 0.3 C, which can be effectively attributed to the strong interaction between CGN separator and Mn ions to prevent the loss of active Mn component.

Compared with single-stage hydrogen bonds, multiple dynamic chemical bonds constructed by 10% hydrogen bonds and 0.25 equiv. metal coordination endowed the polymer semiconductors with an 58% enhancement in carrier mobility and a two-fold increase in crack-onset strain. Notably, the polymer exhibited stable carrier mobilities parallel to the stretching direction, with 91% of initial values even under 150% strain, which is the unprecedented value for intrinsically stretchable semiconducting polymers without blending of elastomers.
