“…[72] Given that added introduction of hydrophilic sulfonic groups might cause excessive swelling of IEMs,a cid-base interactions were introduced by Shi et al,b ym odifying GO with polyaniline or amines and blending them with SPEEK. [73] As expected, the swelling ratio was suppressed, so was the vanadium crossover. To compensate for the expense of -SO 3 Hg roups involved in acid-base interactions,t he same research group proposed an ovel GO modified with zwitterions (ZC-GO) and hybridized it with SPEEK (Figure 6g).…”

Redox flow batteries (RFBs) are among the most promising grid‐scale energy storage technologies. However, the development of RFBs with high round‐trip efficiency, high rate capability, and long cycle life for practical applications is highly restricted by the lack of appropriate ion‐conducting membranes. Promising RFB membranes should separate positive and negative species completely and conduct balancing ions smoothly. Specific systems must meet additional requirements, such as high chemical stability in corrosive electrolytes, good resistance to organic solvents in nonaqueous systems, and excellent mechanical strength and flexibility. These rigorous requirements put high demands on the membrane design, essentially the chemistry and microstructure associated with ion transport channels. In this Review, we summarize the design rationale of recently reported RFB membranes at the molecular level, with an emphasis on new chemistry, novel microstructures, and innovative fabrication strategies. Future challenges and potential research opportunities within this field are also discussed.

“…A series of hybrid SPEEK membranes were fabricated by Yuxia et al 13 using aliphatic amine-functional graphene oxide nanofillers as interface modifiers. They produced membranes containing the primary amine (NH 2 -GO), ethylenediamine (EDA-GO), and 1,6-hexanediamine (HMD-GO).…”

Vanadium redox flow batteries (VRFB) are among the most promising approaches to efficiently store renewable energies. In such battery type, Nafion is commonly used as membrane material but suffers from high vanadium crossover and cost. These drawbacks negatively influence the widespread commercial application of VRFBs. Alternative membrane materials with high performance and low cost are thus being developed to address these shortfalls. Among those, possible materials for the VRFB membrane is sulfonated polyether ether ketone (SPEEK), which recently attracted considerable attention due to its low cost, combined with mechanical and chemical stability, and ease of preparation. This review summarizes the research activities related to the development of SPEEK-based membranes for VRFB applications and gives an overview of the properties of PEEK and its sulfonated form. A critical analysis on the challenges of SPEEK-based membranes is also discussed.

Summary Direct borohydride fuel cell (DBFC) is a liquid fuel cell technology that has a number of advantages, including lower operating temperature as well as great cell voltage when compared with hydrogen as well as alcohol fuel cell. The utilisation of reagent in liquids, under room pressures as well as temperatures, facilitated the internal processes of the fuel cell system and its application. Polymer electrolyte membranes or proton exchange membrane are an important component of fuel cells. Commercial perfluorosulphonic acid type membranes such as Nafion are often used in DBFC systems. However, Nafion has some disadvantages such as high cost, low stability at high temperatures, and low conductivity at low humidity or high temperatures that limit its use in DBFC systems. Thus, this review accounts the cheaper alternative membrane than Nafion that applied for DBFC which is sulfonated poly ether ether ketone (SPEEK) based membrane. The mixing of SPEEK with other filler such as graphitic carbon nitride (g‐C3N4), clay, silica, metal oxide, heteropoly acids, and carbon nanotube is being discussed. The properties of SPEEK membranes performance such as degree of sulfonation, water intake, ionic conductivity, BH4 crossover as well as mechanical strength in DBFC were studied.
