Polymer-ceramic composite articles with relatively low dissipation factor (Df) and relatively high dielectric constant (Dk), as well as polymer-ceramic core-shell powders and pellets adapted for making such composite articles. The ceramic-polymer composites, in powder and / or pellet forms, comprise a plurality of core-shell particles, where: each of the core-shell particles comprises a core and a shell around the core; the core comprises a ceramic that is selected from the group of ceramics consisting of: BaTiO3, SrTiO3, TiO2, CaTiO3, MgTiO3, and combinations of any two or more thereof; and the shell comprises a polymer selected from the group of polymers consisting of: polyetherimide (PEI), polyetherimide (PEI) copolymers, polyphenylene ether (PPE), polyphenylene sulfide (PPS), polyaryl ether ketone (PAEK), polypropylene (PP), polytetrafluoroethylene (PTFE), perfluoroalkoxy alkane (PFA), fluorinated ethylene propylene (FEP), ethylene tetrafluoroethylene (ETFE), polyvinylidene fluoride (PVDF), and ethylene chlorotrifluoroethylene (ECTFE).

The invention discloses a ceramic-polymer composite material for reinforcing a V-grade surrounding rock culvert and a preparation method of the ceramic-polymer composite material, and belongs to the technical field of civil engineering materials. The problems that an existing reinforcing material is difficult to have self-sensing and self-healing functions and functional components are prone to being damaged in the preparation process are solved. The method is characterized by comprising the following steps: dry-mixing fly ash, slag and fibers; preparing an alkali activator; shearing and dispersing the acidized multi-walled carbon nanotubes, a water reducing agent and water to form a carbon nanotube suspension; sequentially adding the carbon nanotube suspension, water and a defoaming agent into the dry powder mixture, and stirring at a low speed for wetting; adding styrene-butadiene latex, stirring and dispersing, adding an alkali activator, and stirring at a medium speed to form slurry; and finally, adding the self-healing microcapsules, and stirring at a low speed until uniform distribution. The prepared material is mainly used for reinforcing a V-grade surrounding rock culvert, and can sense damage in real time and automatically repair cracks.

The invention relates to a method, apparatus, and product for manufacturing lithium-ion batteries, employing a novel z-fold assembly approach with an integrated separator-anode structure. The method involves coating separator layers directly onto both sides of an anode sheet, forming a unified structure that is folded into a z-pattern with cathode sheets positioned between the folds. This innovative assembly technique eliminates the need for a separate separator layer and the die-cutting step for the anode, reducing the number of layers in the assembly process and streamlining manufacturing. By removing the necessity for separate separator placement, the invention reduces production complexity, minimizes risks of misalignment, and enhances assembly precision. The z-fold approach further optimizes the manufacturing workflow by minimizing scrap rates, increasing production speed, and simplifying operations. The integrated separator is composed of advanced materials, including polymers and ceramic-polymer hybrids, offering superior thermal stability, ionic conductivity, and mechanical strength. The invention also introduces an automated apparatus that integrates dual-sided coating, z-folding, and cathode placement processes. Equipped with precision alignment sensors and robust quality control systems, the apparatus ensures scalable, high-efficiency industrial production. Batteries produced using this approach exhibit enhanced cycling stability, reduced internal resistance, and higher energy density, coupled with significant improvements in safety and manufacturing efficiency. The invention is compatible with various battery chemistries, including lithium-ion, and supports applications in consumer electronics, electric vehicles, aviation, and energy storage systems.

The core-shell particles can be in a powder form (e.g., a dry powder). In pellet form, shells of adjacent core-shell particles are joined to resist separation of the adjacent core-shell particles and deformation of a respective pellet. Methods of forming a ceramic- polymer composite comprise: superheating a mixture of the polymer (PEI, PEI copolymers, PPE, PPS, PAEK, PP, PTFE, PFA, FEP, ETFE, PVDF, and / or ECTFE), solvent, and the ceramic (BaTiO3, SrTiO3, TiO2, CaTiO3, and / or MgTiO3), to dissolve the polymer in the solvent; agitating the superheated mixture while substantially maintaining the mixture at an elevated temperature and pressure; and cooling the mixture to cause the polymer to precipitate on the particles of the ceramic and thereby form a plurality of the present polymer-ceramic core-shell particles. Methods of molding a part comprise subjecting a powder or pellets of the present polymer-ceramic core-shell particles that substantially fills a mold to a first pressure while the powder is at or above a first temperature above a glass transition temperature (Tg) or if no Tg then above a melting temperature (Tm) of the polymers.
