“…We note that, in addition, the fluorination of phosphate, vanadate and sulfate‐based CAMs was studied. The following non‐exhaustive list gives an impression on available reports: NaVPO 4 F, Na 3 V 2 (PO 4 ) 2 F 3 , Na 3 (VO 1‐ x PO 4 ) 2 F 1+2x , coated/doped/double treated Na 3 (VO 1‐x PO 4 ) 2 F 1+2x , Na 3‐x Li x V 2 (PO 4 ) 2 F 3 , Na 2 M 1 PO 4 F (M 1 =Co, Fe, Mn), LiVPO 4 F, coated/doped/treated LiVPO 4 F, Li 2 VPO 4 F, Li 3 V 2 (PO 4 ) 3‐z F z , Li 5 V(PO 4 ) 2 F 2 , xLi 3 V 2 (PO 4 ) 3‐y *LiVPO 4 F, LiFeSO 4 F, treated LiFeSO 4 F, LiVSiO 4 F, LiFePO 4 F, LiFePO 4 (OH) x F 1‐x , Li 2 FePO 4 F, Li 2 CoPO 4 F, Li 2 NiPO 4 F, and Li 2 MnPO 4 F …”

“…A further good next generation CAM class are the “Li‐ excess/Li‐rich/over‐lithiated” NCM electrode materials with a general formula of 0.35Li 2 MnO 3 ⋅ 0.65Li[Ni 0.35 Co 0.20 Mn 0.45 ]O 2 . In terms of good safety properties, the lithium metal phosphate (LiMPO 4 ‐M=Fe, Mn, Co, and Ni) and lithium iron fluorosulfate are good choices.…”

In this Review, we report and compare non‐fluorinated with fluorinated cathode active materials (CAMs) based on a nickel‐cobalt‐manganese (NCM) composition such as HE‐NCM, NCM, Ni‐rich, Co‐rich, and Mn‐rich CAMs. We evaluate the CAMs according to their fluoride concentration, the F sources used in the synthesis method, characterization techniques, and battery performance [(initial) capacity or coulombic efficiency at C‐rate before/after cycles and the temperature]. In detail, we address 33 publications with “single” fluorinated NCM CAMs, including F sources such as LiF, [NH4]F, [NH4]FHF, NaF, NiF2, and F2. Furthermore, we give a short overview of 52 articles for “multiple” (anion and cation) treated NCM CAMs. For all reported articles (single and multiple treated NCM CAMs), we give the CAMs, conductive additives, and binder materials, as well their electrolyte compositions.

“…Additionally, reversible hydration reaction of ZnSO 4 from monohydrate to heptahydrate is a promising way to store solar heat energy due to the high enthalpy of hydration (ΔH = ‐58 KJ mol −1 ) 24 . Iron (II) sulfate heptahydrate is also frequently use in low‐cost adsorbent material and up till now, 30 several investigations have been done on xLiF‐FeSO 4 binary composite systems for lithium‐ion batteries as a cathode material 31 . However, as a solar heat storage material (TCMs) for long‐term, FeSO 4 7H 2 O has not been study before in an issues concerning the thermochemical storage technology.…”

Summary Thermochemical heat storage materials offer high‐energy storage densities and clean means of long‐term solar energy storage. The aim of the study is to assess the potential heat storage efficiency of salt hydrates, based on sufficient hydration/dehydration performance, water sorption and cyclicability. MgSO4 7H2O, ZnSO4 7H2O and FeSO4 7H2O were evaluated based on preselected criteria. The main highlights of the dehydration result show that higher enthalpy was obtained for MgSO4 and ZnSO4, shows 2256 and 1731 J g−1 enthalpy, respectively. During hydration process, six water molecules were absorb by MgSO4 and ZnSO4 after pre‐dehydrated temperature 150°C and 120°C, respectively. The cycle stability of MgSO4 and ZnSO4 showed better performance which give rise 1210 g−1 and 1155 J g−1 enthalpy, respectively. It was expected that FeSO4 would show higher cyclicability due to their higher enthalpy (1400 J g−1) in the first round; however, overhydration does not permit it to released larger energy. The impact of relative humidity on water sorption performance and rate of hydration were reported which showed that MgSO4 and ZnSO4 can uptake maximum water under 85% and 75% relative humidity. Ongoing studies and the booming progress of ZnSO4 7H2O illustrate that likewise MgSO4 7H2O, it is also the potential candidate and can be use in thermochemical heat storage devices. To bring zinc sulfate heptahydrate into market, more detail studies in fields of evaluation of advanced materials and development of efficient and compact prototypes are still required.

“…The high-energy mechanical ball milling method is well known as an efficient and convenient approach for the synthesis of nanomaterials, and it is widely applied to the fabrication of cathodes and anodes used for LIBs [8,9] and NIBs [10]. The electrochemical performance of electrodes is improved by decreasing the size of the particles to the nanoscale range.…”

A novel carbonophosphate, Na3MnPO4CO3, was synthesized as a cathode material using a mechanical ball milling method with starting materials of MnCO3 and Na3PO4 without washing or drying. Duo to the formation of nano-size particles and good dispersion of the obtained Na3MnPO4CO3, the initial discharge capacity in an organic electrolyte of 1 M NaPF6/ethylene carbonate (EC): dimethyl carbonate (DMC) (1:1 v/v) was 135 mAh∙g−1 and 116 mAh∙g−1 at 1/30 C and 1/10 C, respectively. We also investigated the cathode properties of Na3MnPO4CO3 in an aqueous electrolyte of 17 m NaClO4. This is the first investigation of the electrochemical performance of Na3MnPO4CO3 with aqueous electrolyte. Na3MnPO4CO3 achieved a discharge capacity as large as 134 mAh g−1 even at a high current density of 2 mA cm−2 (0.5 C), because of the high ionic conductivity of the aqueous electrolyte of 17 m NaClO4.
