Problems solved by technology

[0004] However, in the case of forming a carbon film as in JP-A-10-106585 and JP-A-11-250900, attempts to form a film by a sputtering process with high mass productivity often result in the formation of insulating like Diamond carbon (DLC) film, which has the problem of reducing electrical conductivity
On the other hand, using platinum or gold is expensive and impractical

Embodiment 1

[0087] (Embodiment 1) Embodiment 1 of the present invention will be described with reference to the drawings. First, the battery 1 according to Embodiment 1 will be described. figure 1 is a perspective view of battery 1, figure 2 A partially cut sectional view of the battery 1 is shown. The battery 1 according to Embodiment 1 is a wound type lithium ion secondary battery including a power generating element 20 and an electrolytic solution 60 . In this battery 1 , a power generating element 20 and an electrolytic solution 60 are accommodated in a rectangular box-shaped battery case 10 . The battery case 10 has a battery case main body 11 and a sealing cover 12 . Among components of the battery case 10 , the battery case main body 11 has a bottomed rectangular box shape, and an insulating film (not shown) made of resin is attached to the entire inner surface of the battery case main body 11 .

[0088] The sealing cover 12 has a rectangular plate shape, and closes the openin...

Embodiment 2

[0157] (Embodiment 2) A vehicle 700 according to Embodiment 2 is equipped with a battery pack 710 including the plurality of batteries 1, 401, 501 described above. Specifically, such as Figure 18 As shown, vehicle 700 is a hybrid motor vehicle that is propelled using engine 740 , front electric motor 720 , and rear electric motor 730 . This vehicle 700 has a vehicle body 790 , an engine 740 , a front motor 720 attached to the engine 740 , a rear motor 730 , cables 750 , an inverter 760 , and a rectangular box-shaped battery pack 710 . Among these assemblies, the battery pack 710 accommodates the aforementioned plurality of batteries 1 , 401 , 501 within a rectangular box-shaped battery case 711 .

[0158] Therefore, since the vehicle 700 according to Embodiment 2 is equipped with the above-described battery 1, 401, 501, the vehicle can have good running characteristics and have stable performance.

Embodiment 3

[0159] (Embodiment 3) A hammer drill 800 according to Embodiment 3 has a battery pack 810 including the above-described batteries 1 , 401 , 501 . Hammer drill 800 is a battery-equipped appliance having batteries 1, 401, 501 and battery pack 810, such as Figure 19 shown. In addition, the battery pack 810 is detachably housed in the bottom 821 of the main body 820 of the hammer drill 800 .

[0160] Therefore, since the hammer drill 800 according to Embodiment 3 is equipped with the above-described batteries 1, 401, 501, it is possible to provide a battery-equipped appliance that has good characteristics for hammer drill use and also has stable performance.

Abstract

A battery-dedicated electrode foil (32) includes an aluminum electrode foil (33) in which metal aluminum is exposed, and corrosion-resistant layers (34A, 34B) that are formed on surfaces (33a, 33b) of the aluminum electrode foil, and that are in direct contact with the metal aluminum that forms the aluminum electrode foil, and that are made of tungsten carbide.

Description

technical field [0001] The present invention relates to a battery electrode foil used in a positive electrode plate of a battery, a positive electrode plate, a battery, a vehicle, and a battery-equipped appliance (appliance) using the battery, a method of manufacturing the battery electrode foil, and a positive electrode plate Production method. Background technique [0002] In recent years, along with the widespread use of portable electronic devices (such as cellular phones, notebook personal computers, video camcorders, etc.) and vehicles (such as hybrid electric vehicles, etc.), the The demand for batteries is increasing day by day. Among these batteries, there are batteries using a positive electrode foil whose base material is an aluminum electrode foil. Examples of such batteries include lithium ion batteries employing a positive electrode plate formed by applying a positive electrode active material containing a lithium compound to such an aluminum electrode foil. ...
