A problem to be solved by the present invention is that there is no method for forming a dense structure on a porous structure at low cost. In addition, another object is to provide a high quality and inexpensive structure of a brittle material and a laminate thereof as an intermediate layer for facilitating formation of a dense structure on a porous structure. A structure is provided having a brittle particle assembly having a plurality of brittle particles, wherein the brittle particle assemblies are arranged adjacently to each other, and the brittle particles having a brittle material region in the periphery are crosslinked (connected) by the brittle material region to bond the brittle particles to each other, and thereby form a brittle material crosslinked structure region preventing the mobility of the brittle particles.

The embodiment of the present application relates to the field of Li-ion battery and, in particular, to a secondary battery. The secondary battery includes a cell, a safety component fixed on the cell and thermal conductive adhesive provided between the cell and the safety component, the thermal conductive adhesive contains at least one of hot melt adhesive, silica gel binder or epoxy resin binder, and thermal conductive filling material. The thermal conductive adhesive in the secondary battery performs good thermal conductivity and adhering property, which can stably adhere the safety component with the cell, meanwhile transferring, via the thermal conductive adhesive, heat of the cell to the safety component rapidly, so that the safety component cuts off the circuit to protect the cell during overcharge, thereby avoid situations that the thermal conductive adhesive is separated from the cell due to cell inflation and deformation.

The present invention relates to a method for preparing a benzoxazine-containing resin composition and a prepreg and a laminate made therefrom. The method for preparing a benzoxazine-containing resin composition is adding an acidic filler to a benzoxazine-containing resin composition. By adding an acidic filler to the benzoxazine-containing resin composition, the present invention promotes greatly the polymerization reaction of benzoxazine and epoxy resin, reduces the curing temperature required for polymerization of benzoxazine and epoxy resin. The laminate prepared from the benzoxazine-containing resin composition, to which an acidic filler is added, has high anti-stripping stability, high glass transition temperature, low water absorption, high heat resistance, high bending strength and good processability, and can achieve low coefficient of thermal expansion.
