Excellent Cycling Stability

Highly efficient electrode materials were constructed from polyaniline/cellulose microspheres (PANI/PA/CM)viaphytic acid (PA) as “bridge” through hydrogen bonding. The electrodes exhibited excellent cycling stability and high rate capability as a result of the superior affinity of cellulose with the electrolyte and the homogeneous nanoporous architecture, leading to good ion channels.

Coated Separator

The adhesion between electrode and separator is a key feature in cell assembly. Nafion™-coated separators for water-processed LiNi0.5Mn1.5O4 (LNMO) electrodes are here proposed as an alternative to the polyolefin separators. Specifically, polyolefin separators are modified with Nafion™ solutions and their adhesion to high-potential LNMO electrodes is investigated. The physicochemical properties of the Nafion™-coated separator and its electrochemical performance in Li/LNMO cells are discussed and compared to those obtained with polyolefin Celgard® (Charlotte, NC, USA) PP2075 separator. Improved adhesion and cycling stability, which could be further enhanced by a mild lamination process, were demonstrated with a thin layer of Nafion™ (0.1 mg cm−2).
