JP_2020021736_A

Resumen de: GB2581071A

An electrode comprises a conductive substrate 105, and a material comprising (i) a plurality of carbon nanofibres 110 acting as support fibres; (ii) a binder 1140; (iii) a faradaic material that interacts with charge carriers on a surface of the material, which comprises an intercalation material 1610; and (iv) a plurality of nanoparticles 1430. The intercalation material may be Si and may be coated on the carbon nanofibres, and the nanoparticles may be concentrated on the surface of the intercalation material (figure 18). The carbon nanofibres may be detached from the substrate and connected thereto via the binder (as shown), or may be directly connected to the substrate, preferably in an array of vertically aligned fibres (Fig 14). The highly conductive and mechanically stable CNF core supporting a coaxially coated amorphous Si shell is claimed to have a higher theoretical specific capacity by forming a fully lithiated alloy. Addition of the nanoparticles provide surface effect dominant sites in close proximity to the intercalation medium, resulting in a hybrid device that includes advantages of both batteries and capacitors.

INTEGRATED ALL-SOLID-STATE SECONDARY BATTERY

Nº publicación: EP3691013A1 05/08/2020

Solicitante:

SEVEN KING ENERGY CO LTD [KR]

CN_111164815_A

Resumen de: EP3691013A1

In order to improve the safety of a rechargeable battery, methods for manufacturing the rechargeable battery using a solid-state electrolyte are being studied. However, a process of manufacturing the all-solid state rechargeable battery by separately preparing and laminating an electrode and a solid-state electrolyte is not only complicated, but also may cause side reactions due to residual moisture between the electrode and the solid-state electrolyte. In addition, additional processes are required to reduce the interface resistance between the electrode and the solid-state electrolyte. In order to solve these disadvantages, the present invention is to manufacture an integral all-solid state rechargeable battery by applying a mixed slurry of a conductive ceramic material and a polymer mixed with a solvent onto an electrode, evaporating the solvent, absorbing a liquid electrolyte, and then covering the electrode with a counter electrode. The manufacturing method of the integral all-solid state rechargeable battery has an effect of simplifying the manufacturing steps, suppressing side reactions, and reducing the interface resistance between the electrode and the solid-state electrolyte.
