Abstract
<jats:p>The purpose of this work is to investigate the structure and mechanism of long‐range electronic contacts which are formed by wet mixing and their interaction and relationship with the structure responsible for ion‐transfer within the conductive binder domain of next‐generation LiNi<jats:sub>0.6</jats:sub>Mn<jats:sub>0.2</jats:sub>Co<jats:sub>0.2</jats:sub>O<jats:sub>2</jats:sub> lithium‐ion batteries. This paper introduces a novel concept involving an efficient adapted structure model, which includes a bridge structure with two “nested” small and large pore systems, and an effective electrode conduction mechanism involving two “nested” percolation systems. The paper also highlights a limitation in the improvement of the battery performance by percolation systems for electron transfer, which is restricted by pore systems for ion transfer through the ratio of electrical conductivity (<jats:italic>σ</jats:italic>) and ionic conductivity (<jats:italic>κ</jats:italic>) as <jats:italic>σ</jats:italic>/<jats:italic>κ</jats:italic> = 10. The findings of this paper may provide valuable insight for formulation design and manufacturing of an optimal structure of the conductive binder domain for next‐generation lithium‐ion batteries.</jats:p><jats:p>This article is protected by copyright.
