Case Study

Cellulose Acetate-Ammonium Tetrafluoroborate-Based Polymer Electrolyte

Harun N I, et al. Materials Research Innovations, 2011, 15(sup2), s168-s172.

Proton conducting polymers were prepared using cellulose acetate (CA) as the main polymer and ammonium tetrafluoroborate (NH4BF4) as the proton source complex. In order to improve the performance of the proton conducting polymer, polyethylene glycol 600 (PEG) was introduced as a plasticizer. The conductivity study results showed that the temperature dependence of both CA-NH4BF4 and CA-NH4BF4-PEG600 systems exhibited Arrhenius behavior.
Preparation of plasticised polymer electrolyte
· Preparation of CA-NH4BF4
A total of one gram of CA was dissolved in 30 mL of acetone, stirring with a magnetic stirrer for 12 hours. Subsequently, varying weight percentages (ranging from 5 to 45 wt-%) of NH4BF4 were introduced into the polymer solution, which was continuously stirred for a minimum of 24 hours at room temperature (27°C) to ensure a homogeneous mixture. Each resultant sample was then poured into Petri dishes and allowed to dry for several days, forming a thin film.
· Preparation of CA-NH4BF4-PEG600
The plasticized polymer electrolytes were created by incorporating PEG600 as a plasticizer into the optimal CA-NH4BF4 solution, using various weight percentages from 0 to 40 wt-% to achieve the highest conductivity in the salted sample. All samples were produced utilizing the solution cast technique.

Synthesis of ZIF67 Derivatives Induced by Ammonium Tetrafluoroborate

Kuo T R, et al. Journal of Energy Storage, 2023, 68, 107831.

Ammonium tetrafluoroborate (NH4BF4) was used as a structure directing agent (SDA) for the synthesis of zeolitic imidazolate framework 67 (ZIF67) derivatives, which were then annealed at various temperatures for oxidation to form cobalt nickel oxides as electroactive materials. The study showed that the novel SDA of NH4BF4 is promising for the design of other effective electroactive materials for efficient energy storage.
The resulting oxidized ZIF67 derivatives exhibited a unique leaf-like structure and a composition of cobalt/nickel oxides, irrespective of the oxidation temperature. The oxidized ZIF67 derivative created at 450 °C achieved the highest capacitance factor (CF) of 828.9 F/g, attributed to its advantageous two-dimensional (2D) leaf-like structure and (311) crystal facet. In comparison, the oxidized ZIF67 and the original ZIF67 electrodes recorded CF values of 519.9 and 5.0 F/g, respectively.
The optimized battery system utilizing the oxidized ZIF67 derivative as the positive electrode and graphene as the negative electrode demonstrated an impressive energy density of 10.2 Wh/kg at a power density of 357 W/kg, along with a CF retention of 91% and a Coulombic efficiency of 97% following 10,000 charge/discharge cycles. The novel SDA of NH4BF4 is expected to be used to design other effective electroactive materials for efficient energy storage.
