Herein, a cathodic electrodeposition method is presented to activate NiFe-based MOF nanosheets on a nickel foam (NF) support to form a NiFe-MOF/(oxy)hydroxide nanocomposite (A-NiFe-TDC). This activation route not only creates abundant defective structures but also involves partial valency reduction in Ni/Fe species and electron transfer to grow a new component of NiFe-(oxy)hydroxide on the surface of the NiFe-TDC MOF. By adjusting electrodeposition times and Ni/Fe mol ratios, the as-prepared A-NiFe-TDC-5 nanocomposite exhibits improved electrocatalytic performance for OER in an alkaline medium, achieving a high current density of 100 mA cm<sup>−2</sup> at a low overpotential of 242.9 mV, a small Tafel slope of 24.9 mV dec<sup>−1</sup>, and good long-term stability over 450 h. After OER, A-NiFe-TDC-5 is self-reconstructed to form NiFe-OOH nanosheets, contributing to optimizing the electronic structures and further improving the electrocatalytic activity and stability.

Proper amount of Ta doping not only increases the interlayer spacing for fast Li<sup>+</sup> transport, but also improves the electrical conductivity, being successfully proved by experimental analyses.

Effectively addressing these issues while retaining high ionic conductivity remains a major obstacle. In this study, Ce was introduced into the Ga-LLZO lattice via an in situ tuning strategy, which significantly reduced internal pore retention and suppressed the reduction of migrating Li<sup>+</sup> into dead lithium. The optimized Ce in situ tuning controlled Ga-LLZO achieved an ionic conductivity exceeding 1 mS cm<sup>−1</sup> at 25 °C, while the critical current density (CCD) in lithium symmetric cells reached 0.7 mA cm<sup>−2</sup>—twice that of unmodified Ga-LLZO. Remarkably, no short-circuiting occurred even after 2700 h of cycling at 0.3 mA cm<sup>−2</sup>, in contrast to the unmodified Ga-LLZO, which failed after only 50 h. The corresponding full cells also demonstrated excellent cycling stability and ultra-high capacity retention, significantly outperforming unmodified Ga-LLZO. Compared with recent electrolyte modification strategies, the Ce in situ tuning controlled Ga-LLZO delivers outstanding overall performance.
