ALL-SOLID-STATE BATTERY - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240234737 titled 'ALL-SOLID-STATE BATTERY

The abstract describes an all-solid-state battery designed to prevent an increase in resistance ratio. The battery includes an anode active material layer with alloy-based active material, first fibrous carbon, and second fibrous carbon. The ratio of fiber diameters between the two carbon types is 10 to 300, and the proportion of the second fibrous carbon to the total carbon content is 0.5% to 10%.

  Scaling up production requires overcoming manufacturing challenges, ensuring cost-effectiveness, and optimizing performance at larger scales.


Original Abstract Submitted

provided is an all-solid-state battery capable of suppressing a rise in the resistance increase ratio thereof. the all-solid-state battery includes an anode active material layer containing an alloy-based active material, a first fibrous carbon, and a second fibrous carbon, wherein when a fiber diameter of the first fibrous carbon is defined as a, and a fiber diameter of the second fibrous carbon is defined as b, the ratio of a to b is 10 to 300, and when the proportion (wt %) of the first fibrous carbon to the alloy-based active material is defined as x, and the proportion (wt %) of the second fibrous carbon to the alloy-based active material is defined as y, the proportion ({y/(x+y)}�100%) of the contained second fibrous carbon to a total of the first fibrous carbon and the second fibrous carbon is 0.5% to 10%.
