Exploring the use of butadiene rubbers as a binder in composite cathodes for all-solid-state lithium batteries

Towards Efficient Polymeric Binders for Transition Metal Oxides‐based Li‐ion Battery Cathodes

“…[51] Lee and coworkers synthesized a polymer binder (NBR25) for composite cathodes by incorporating polybutadiene and acrylonitrilebutadiene rubbers with different acrylonitrile contents. [52] Morphological and mechanical evaluations of the composite cathodes verified that NBR25 strongly attached to NMC721 and Li 6 PS 5 Cl particles due to the existence of nitrile groups and accommodated the mechanical stress induced by the volume variation of cathode particles, thus ensuring good interfacial contact between the cathode components over repeated cycling. This work provides essential structural elements for designing ionic-conductive and elastic binders for all solid-state battery systems.…”

Revealing interfacial parasitic reactions of nitrile rubber binders in all-solid-state lithium batteries

“…30,31 Moreover, additional adhesion properties by polymeric binders enable the battery to perform better by alleviating crack formation and delamination of the composite electrode during the charge–discharge process. 32,33 Therefore, many researchers have explored various binder materials, including rubber binders such as nitrile butadiene rubber (NBR) 24,28,29,34 and polybutadiene (PB), 34,35 as well as fluorine binders such as polyvinylidene fluoride- co -hexafluoropropylene (PVdF-HFP). 36 Despite these efforts, establishing standard polymeric binders that are fully compatible with sulfide-type solid electrolytes remains a challenge.…”

A Highly Efficient Additive for Direct Reactivation of Waste LiFePO4 with Practical Electrochemical Performance

“…20 Adhesive improvement can effectively fix the material and provide a stable structure through improved bonding performance and mechanical strength. 21 There are many research directions to advance the electrochemical performance of LiFePO 4 , but rarely has the focus been on the dispersants used in the mixing process of LiFePO 4 precursors. Dispersants are used to stabilize the particles, powders, or liquids in the dispersion system during the preparation process, so that they are homogeneously distributed in the solution or matrix.…”

“…For example, alloying with metals such as copper and aluminum can improve the conductivity and ion diffusion rate of the material. , Structural optimization is to optimize the ion diffusion path and electron transport channel by changing the crystal structure of LiFePO 4 or doping other elements, to enhance the electrochemical performance of the material . Adhesive improvement can effectively fix the material and provide a stable structure through improved bonding performance and mechanical strength . There are many research directions to advance the electrochemical performance of LiFePO 4 , but rarely has the focus been on the dispersants used in the mixing process of LiFePO 4 precursors.…”
