“…The powder compression method also allows for the addition of a binder to create a conventional electrode system containing active materials, conductive agent, and binder. In 2023, Zhe Zhang et al [64] reported a dry LFP cathode preparation process using PPC as a binder. A powder mixture of LFP, multiwall CNTs mixed with CB, and PPC with a mass ratio of 88:10:2 was first directly ball-milled for 12 h, and then hot-pressed at 120 • C to form electrodes (Figure 10a).…”

“…[43] The fluorinated part has good electrochemical stability and adhesive properties; the PEO fragment of PEGMA enhances its hydrophilicity and provides Li + conductivity. Zhang et al [44] used PPC as binder to produce dry LFP electrodes (Active material : Conductive material : Binder = 88 : 10 : 2) with high loading (~20 mg cm À 2 ). The high content of carbonate bonds in PPC can provide a channel for the transfer of Li + , thus effectively improving the electrochemical properties of the LFP electrode.…”

Polymeric binders account for only a small part of the electrodes in lithium‐ion batteries, but contribute an important role of adhesion and cohesion in the electrodes during charge/discharge processes to maintain the integrity of the electrode structure. Therefore, polymeric binders have become one of the key materials to improve the charge/discharge properties of lithium‐ion batteries. Qualified polymer binders should not only require good bond strength, mechanical properties, conductivity, chemical functionality and processing performance, but also be environmentally friendly and low cost. The existing commercial polymeric binders cannot meet all the above requirements at the same time. This is a hot research area that researchers are keen to focus on, and it is hoped that through structural design, the matching of functional groups can meet the requirements of high‐capacity lithium‐ion batteries with long cycle life. Focusing on the structural design of polymer binders, the mechanism of interaction with electrode materials, and the functional properties of polymer binders, this review summarizes the polymer binders used in the cathode and anode in recent years. It could expect that this review can inspire a deep consideration on these critical issues, paving new pathways to improve comprehensive performance of polymer binders.
