Capacity degradation is the main failure mode of lead–acid batteries. Therefore, it is equivalent to predict the battery life and the change in battery residual capacity in the cycle. The definition of SOH is shown in Equation (1): where Ct is the actual capacity, C0 is nominal capacity.
The extracting and manufacturing of copper used in the anode is the highest contributor among the materials. Consequently, for the lead-acid battery, the highest impact comes lead production for the electrode. An important point to note is that there are credits from the end-of-life stage for all batteries, albeit small.
Compared to the lead-acid batteries, the credits arising from the end-of-life stage of LIB are much lower in categories such as acidification potential and respiratory inorganics. The unimpressive value is understandable since the recycling of LIB is still in its early stages.
The LIB outperform the lead-acid batteries. Specifically, the NCA battery chemistry has the lowest climate change potential. The main reasons for this are that the LIB has a higher energy density and a longer lifetime, which means that fewer battery cells are required for the same energy demand as lead-acid batteries. Fig. 4.
Conclusions In this paper, the health status of lead–acid battery capacity is the research goal. By extracting the features that can reflect the decline of battery capacity from the charging curve, the life evaluation model of LSTM for a lead–acid battery based on bat algorithm optimization is established.
At 56%, the manufacturing process of battery cells contributes the most to the acidification impact for the LFP batteries. The increased contribution is caused by the chemical reaction necessary to produce LFP cathodes, which generates a relatively high amount of mole H + eq.

Technology: Lead-Acid Battery
There are two general types of lead-acid batteries: closed and sealed designs. In closed lead-acid batteries, the electrolyte consists of water-diluted sulphuric acid. These batteries have no gas-tight seal. Due to the electrochemical potentials, water splits into hydrogen and oxygen in a closed lead-acid battery.

Aging mechanisms and service life of lead–acid batteries
In lead–acid batteries, major aging processes, leading to gradual loss of performance, and eventually to the end of service life, are: • Anodic corrosion (of grids, plate-lugs, straps or posts). • Positive active mass degradation and loss of adherence to the grid (shedding, sludging). • Irreversible formation of lead sulfate in the active mass (crystallization, sulfation). • …
