The present disclosure relates to a rechargeable lithium battery. More particularly, the rechargeable lithium battery includes an electrode substrate, an electrode active material block coated on the electrode substrate, and a membrane stacked on the electrode active material block. The electrode…

A secondary battery positive electrode includes a belt-shaped positive electrode current collector with two regions and a positive electrode mixture thereon. The first region being at both ends and the second region is a central area. The positive electrode mixture layer includes a first positive…

The present disclosure provides an electrode for a secondary battery capable of measuring the width of a first mixture layer and the width of a second mixture layer when the first mixture layer and the second mixture layer are stacked and formed on the surface of a metal foil. A positive electrode…

An electrode structure of a flow battery. A density of the vertical tow in the electrode fiber is larger than the density of the parallel tow. In the electrode fiber per unit volume, the quantity ratio of the vertical tow to the parallel tow is at least 6:4. The electrode structure includes an odd…
