“…Recently, a wood‐inspired lignin binder was developed for practical S cathodes after modification with amino acids. [ 15 ] Due to the existence of carboxyl and hydroxyl groups (Figure 5c), the lignin promises the dispersion of active/conductive mixture as well as the uptake of LiPS. Moreover, binders with ultra‐low low dosage are expected to maximize the energy density of electrode and significantly increase the bulk resistance of the whole battery.…”

“…Furthermore, they are low cost and easily accessible due to resource abundance. [ 15 ] Although these high‐capacity electroactive materials still face striking challenges, such as huge volume variation during the Li insertion/extraction process, rational structural design and morphological optimization have been correspondingly proposed, [ 17 ] in which, partial research results have been transferred to practical applications. Apart from that, efforts have also been extended to inactive materials, such as polymeric binders, conductive additives, and current collectors.…”

The upsurging demand for electric vehicles and the rapid consumption of lithium‐ion batteries (LIBs) calls for LIBs to possess high energy density and resource sustainability. The former requires the usage of electroactive materials with high capacity and the maximum amount within the fixed electrode volume. The latter essentially creates a closed‐loop circulation scenario for electroactive materials. In all aspects, binders are of practical significance in bonding electroactive materials, maintaining electrode integrity and detaching electrode slurry from the current collector. Currently, the key role of binders in enhancing the electrochemical behavior of sustainable high‐capacity electroactive materials has been recognized. Meanwhile, binders that are designed for easy and cost‐effective recycling of electroactive materials are gradually reported. Herein, recently developed binders that hold promises in establishing sustainable high‐energy‐density LIBs are summarized. The role of binder in facilitating easy separation of electroactive materials are first highlighted. Subsequently, special attention is paid to conductive binders, contributing to less battery chemistries and higher energy density of electrode. Additionally, progress of emerging binders in high‐capacity electroactive materials are also reviewed. It is believed that the advances in binders will open up opportunities for establishing a sustainable high‐energy‐density battery economy.

“…[12,13] Number of novel multifunctional binders with adsorption function have been developed to substitute PVDF, such as saccharide-based binder (CMC/G), [14] crosslinked alginic acid-isosorbide (c-Alg-IS), [15] sodium alginate-Cu (SA-Cu), [16] water-soluble functional polymer binder (GN-BA), [17] zwitterionic polymer binder (ZIP), [18] and others. [19][20][21] Despite the excellent performance obtained with these binders, they only focus on the properties of LiPSs adsorption, while acceleration redox kinetics has been rarely explored (Figure 1b), resulting in poor electrochemical improvement at high sulfur loadings. [22] A prospective binder for Li-S batteries not only effectively adsorb LiPSs to suppress shuttle effects, but also accelerate S-S bond breaking or Li + transport to catalyze the conversion of LiPSs, additionally with essential adhesion.…”

The commercial application of lithium–sulfur (Li–S) batteries is severely impeded by abominable shuttle effects, sluggish redox kinetics, and poor safety performance under high loading conditions. Herein, a novel adsorption‐mediator synergistic polymer binder (PAT) is reported to regulate the conversion of lithium polysulfides (LiPSs) through close intermolecular synergy. The abundant polar groups provide strong anchor ability for LiPSs to effectively inhibit the shuttle effect, and the anchored LiPSs are accelerated by adjacent mediator catalytic sites to facilitate their redox kinetics. Moreover, PAT itself features excellent flame retardant properties, which effectively enhance the safety performance of Li–S cells. Benefiting from these attributes, PAT‐based Li–S cells exhibit outstanding rate performance with an average capacity of 617.34 mAh g−1 at 5 C and excellent cycling stability maintaining a capacity of 629.1 mAh g−1 after 800 cycles at 2 C. Even under the harsh conditions of high loading (9.84 mg cm−2) and lean electrolyte (E/S = 3.56 µL mg−1), PAT‐based cell delivers a high average areal capacity of 9.58 mAh cm−2 and an ultralow overpotential of 3 mV, confirming the application potential of adsorption‐mediator synergistic polymer binder in high performance Li–S batteries.

Binder plays an important role in maintaining the integrity of sulfur electrode in lithium‐sulfur (Li‐S) battery. However, cracks are easily generated inside the electrode and compromise its performance due to the volume change of sulfur during redox reaction and continuous vibration originated from the external environments. It is a challenge yet crucial to develop tough binders with crack‐insensitivity and damping performance. Herein, a polymeric binder is designed with special viscoelastic behavior by tailoring its electrolyte‐philic and electrolyte‐phobic domains. The loss modulus of the binder is regulated to be highly close to its storage modulus within a wide range of frequency, generating an ultra‐high loss factor and equilibrium of viscosity‐elasticity. Based on such rheological behavior, the binder holds 1) high damping ability across a wide frequency to suppress crack generation, 2) high toughness with crack blunting behavior to resist crack propagation, 3) efficient healing capability to repair the cracks. Besides, the pendant zwitterionic groups can immobilize the lithium polysulfides and promote ion transfer. Benefiting from these advantages, the obtained Li‐S battery delivers high specific capacity with considerable capacity retention after long‐term cycling. The viscoelastic design and crack management strategy illustrated here would provide new insights into the binder design.
