Positive electrodes for Li-ion and lithium batteries (also termed “cathodes”) have been under intense scrutiny since the advent of the Li-ion cell in 1991. This is especially true in the past decade.
Positive electrodes made of lead-calcium-tin alloy. 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.
Ultimately, the development of electrode materials is a system engineering, depending on not only material properties but also the operating conditions and the compatibility with other battery components, including electrolytes, binders, and conductive additives. The breakthroughs of electrode materials are on the way for next-generation batteries.
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).
At the microscopic scale, electrode materials are composed of nano-scale or micron-scale particles. Therefore, the inherent particle properties of electrode materials play the decisive roles in influencing the electrochemical performance of batteries.
Minimizing the particle size to the nanoscale is a well-known approach for improving the kinetics of electrode materials. In this way, the shorten ion diffusion path and the increased surface area are conductive to increase the charge transfer reaction on the surface with the electrolyte (Kim, Jeong, Yoon, & Kang, 2020).
