The preparation of the positive electrode was the same as that for Na metal coin cells, which had a single-side coating and a diameter of 16 mm. FeS electrode was fabricated by mixing FeS material, conductive carbon (super P), and sodium carboxymethyl cellulose in water at a mass ratio of 8:1:1.
Lead, tin, and calcium were the three main components. Other elements constitute ~0.02 wt% of the sample. Corrosion potential and current, polarization resistance, electrolyte conductivity, and stability were studied. IL was selected as an effective additive for capacity tests of the positive electrode.
The positive electrode of the LAB consists of a combination of PbO and Pb 3 O 4. The active mass of the positive electrode is mostly transformed into two forms of lead sulfate during the curing process (hydro setting; 90%–95% relative humidity): 3PbO·PbSO 4 ·H 2 O (3BS) and 4PbO·PbSO 4 ·H 2 O (4BS).
To prepare the positive electrode, the active material was mixed with super carbon and polyvinylidene fluoride (weight ratio 90: 5: 5) in N-methyl-2-pyrrolidone (NMP). Then the slurry was cast onto aluminum foil with a 250 μm scraper and dried overnight in a vacuum oven at 100 °C.
The lower efficiency in a positive electrode could be because of the oxidation of CNTs .
Moreover, in the positive electrode, the premature loss may occur with inadequate doping (e.g., tin and antimony) since the dopant may improve the contact between the polymer chains and link them into an integral system with high electrical conductivity.
