High-performance supercapatteries have gained excellent research interest due to their high energy-power delivering capability, rapid charge/discharge, and prolonged cycle life. However, their low specific capacitance, poor rate capability, and inferior energy density of the electrode material constrained their practicality. In numerous energy storage devices, perovskite oxides achieve great importance due to their structural stability and electron conductivity. In the present work, binder-free CeNiO 3 (CNO) nanoparticles are grown on Ni-foam as a supercapattery electrode material. The CNO nanoparticles are successfully grown on Ni-foam as a current collector using a one-step hydrothermal method and an annealing process. This nanostructured perovskite oxide in the Ni-foam reduces the agglomeration and provides efficient pathways for fast charge transport. The synergistic effect, and varying valence states of Ce and Ni in the perovskite structure elucidate fast charge transfer kinetics. The CNO@Ni-foam electrode exhibits the highest specific capacity of 278 C g À1 at 1 A g À1 in a 6 M KOH electrolyte. Further, the constructed symmetric cell CNO//CNO operates at 1.55 V and exhibits high specific capacity (179.81 C g À1 ), high energy density (38.70 W h kg À1 ), and high-power density (7750 W kg À1 ) with long cycle durability (20 000 cycles). The supercapattery exhibits outstanding rate capability and good cyclic stability of 92% from its maximum specific capacity at a current density of 5 A g À1 .

“…In binder-free textile coloration and other related applications, − the film-forming copolymer encapsulated P.R-170 hybrid latex particles were directly immobilized on the fabrics. The change in the ratio of hard and soft monomers (MMA and BA) not only reduced the glass transition temperature ( T g ) of the shell copolymer, but also affected the particle size, PDI, and morphology of hybrid latex particles. , Four groups of the film-forming copolymer/P.R-170 hybrid latexes were prepared via SF-RAFT emulsion polymerization with different ratios of MMA and BA (Table , run 2–5).…”

Reversible addition−fragmentation chain-transfer (RAFT)-mediated hybrid emulsion polymerization is an in situ growth method of increasing interest for preparation of colloidal polymers/inorganic hybrid latex with precise structures and properties. However, the challenges of the conventional organic sulfur-based RAFT agents causing color and undesired odor problems still attract attention. In response to this problem, herein, a cationic amphipathic statistic sulfur-free (SF) macro-RAFT agent with a vinyl end group is proposed to disperse organic pigment particles (C.I. Pigment Red 170), where the vinyl group is the living point to regulate the sulfur-free and surfactant-free RAFT hybrid emulsion polymerization of methyl methacrylate (MMA) or MMA with butyl acrylate (BA). Benefitting from this SF macro-RAFT agent acting as both coupling agent and stabilizer, the "living" chain growth of the polymers onto the C.I. Pigment Red 170 surface causes the formation of encapsulating pigment hybrid particles as proven by size-exclusion chromatography and transmission electron microscopy analyses. As a proof-of-concept experiment, the film-forming P(MMA-co-BA)/pigment hybrid latex particles are applied to textile colorants to pad dyeing cotton fabric. Owing to the unique structure of hybrid particles with high pigment content (81.3%), the dyed cotton fibers exhibit high color strength, dryand wet-rubbing fastness, good air permeability, and softness in comparison with the traditional mixture system. This study will not only broaden the area of RAFT-mediated hybrid emulsion polymerization for preparing hybrid particles but also provide a facile application for clear production.

“…They use high temperature vapor, electric elds and other means to guide the deposition of catalytic groups on the substrate to make electrodes, which are widely used in batteries that do not need gas to participate in the reaction. [105][106][107] The other is the one-time synthesis method, that is to integrate the air electrode synthesis, and usually the precursors are congured in advance and then the air electrode layer is obtained directly through high-temperature and high-pressure carbonization. This method is appropriate for making porous and breathable structures, which are more suitable for metal air batteries.…”
