Embodiment Construction

[0067] The electrode for an electrical storage device of the present invention will be described below using the drawings, but the electrode for an electrical storage device of the present invention is not limited to the description below.

[0068] figure 1 It is a cross-sectional view schematically showing an example of the electrode for an electrical storage device of the present invention.

[0069] like figure 1 As shown, the electrode 10 for an electrical storage device includes a current collector plate 20 , electrode portions 30 formed on both surfaces of the current collector plate 20 , and lead wires 40 connected to ends of the current collector plate 20 .

[0070] In addition, the lead-out part 21 and the main body part 22 are formed of the same quality stainless steel.

[0071] In addition, the stainless steel forming the current collector plate 20 is austenitic stainless steel including a martensitic structure.

[0072] In addition, the electrode portion 30 conta...

Abstract

Provided is a storage device electrode with high strength for which high connection reliability is secured, even when a current collector plate, in which an electrode unit including silicon as an active material is disposed, is used. The storage device electrode of the present invention is characterized by comprising: a current collector plate configured from a body part and a lead-out part; an electrode unit disposed in the body part of the current collector plate; and a lead line connected to the lead-out part of the current collector plate, wherein the lead-out part and the body part are formed from the same material of stainless steel, the stainless steel is austenitic stainless steel including the martensite structure, and the electrode unit includes silicon as an active material.

Description

technical field [0001] The present invention relates to an electrode for an electrical storage device, an electrical storage device, and a method for manufacturing an electrode for an electrical storage device. Background technique [0002] Electricity storage devices using metals with a high tendency to ionize lithium are used in many fields because they can store large amounts of energy. [0003] As a method of manufacturing such an electrical storage device, Patent Document 1 discloses a method of manufacturing an electrical storage device including: a positive electrode formed on a positive electrode current collector having a through hole; The negative electrode formed on the negative electrode collector plate and the non-aqueous electrolyte containing lithium salt, the positive electrode contains a carbonaceous material with a layered structure capable of inserting and extracting anions as the positive electrode active material, and the negative electrode contains a ca...
