Generally a passivating layer called the SEI is formed on the negative and positive electrodes of LIBs as a result of electrolyte decomposition, mainly during the first cycle. 20 The SEI is a lithium-ion conductor but an electronic insulator, which mainly consists of polycrystalline materials.
Some important design principles for electrode materials are considered to be able to efficiently improve the battery performance. Host chemistry strongly depends on the composition and structure of the electrode materials, thus influencing the corresponding chemical reactions.
In addition, coating active electrode materials with a conductive layer or embedding the active electrode materials in a conductive matrix can also efficiently improve the electron conductivity of the whole electrode. The structural stability of electrode materials includes two main aspects, the crystal structure and the reaction interface.
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.
