A secondary battery includes: an electric cell layer including a stack structure sequentially including: a positive electrode layer, a separator layer, and a negative electrode layer having an electrolyte higher in conductivity than an electrolyte of at least one of the separator layer and the positive electrode layer.

Secondary battery and method of producing the secondary battery

The present invention provides a composite positive electrode material for a lithium ion battery, which is particularly excellent in high-rate discharge characteristics in a battery, and also provides a slurry, positive electrode and battery using the composite positive electrode material. The composite positive electrode material for a lithium ion battery contains: a positive electrode active material (a); a conductive material (b) having a primary particle diameter of 10 to 100 nm and/or a fibrous conductive material (c) having a fiber diameter of 1 nm to 1 &#x3bc;m; and a conductive material (d) having an aspect ratio of 2 to 50.

Composite positive electrode material for lithium ion battery and battery using the same

The invention relates to fuel cells and methods of making bipolar fuel cell electrodes. The invention provides a method of producing bipolar fuel cell electrodes, including providing a collector having a first side and a second side opposite the first side, coating the first side with a first active material, coating the second side with a second active material, and compressing the coated collector to form a bipolar cell electrode. The invention also provides a method of producing bipolar fuel cell electrodes wherein the first side of the collector is first coated with the first active material and compressed at a first pressure, and subsequently the second side of the collector is coated with the second active material and compressed at a second pressure. The invention further provides an improved bipolar electrode for fuel cells.
