Abstract

The invention provides an electrode active substance by which ionic conductivity can be enhanced, and an all-solid battery using the electrode active substance, etc. A negative electrode active substance 4 is used for a negative electrode layer 30 of an all-solid battery 100 and contains a plurality of secondary particles. The plurality of secondary particles contain impregnated particles which are secondary particles having a polymer solid electrolyte region impregnated with the polymer solid electrolyte therein and an active material region.

Description

technical field [0001] The present application relates to an electrode active material, a method for producing the same, and an all-solid battery using the electrode active material. Background technique [0002] In recent years, the development of reusable secondary batteries has been demanded due to weight reduction and wirelessization of electronic devices such as notebook computers and mobile phones. As the secondary battery, there are nickel-cadmium batteries, nickel-hydrogen batteries, lead storage batteries, lithium-ion batteries, and the like. Among these, lithium-ion batteries have attracted attention due to their light weight, high voltage, and high energy density. [0003] In the field of automobiles such as electric vehicles and hybrid vehicles, the development of high-capacity secondary batteries is highly valued, and the demand for lithium-ion batteries tends to increase. [0004] A lithium ion battery is composed of a positive electrode layer, a negative ele...
