AI Customer ServiceLow active material loading in the composite electrode of all‐solid‐state batteries (SSBs) is one of the main reasons for the low energy density in current SSBs.
AI Customer ServiceEvery time a battery is discharged a small portion of the active material falls to the bottom, reducing its overall capacity, this is known as shedding. This material slowly accumulates at the base and will eventually lead to battery failure.

AI Customer ServiceLead-acid batteries, widely used across industries for energy storage, face several common issues that can undermine their efficiency and shorten their lifespan. Among
AI Customer ServiceThis not only extends the process chain, but also reduces the purity of the recovered cathode materials .Thus, battery cells should be disassembled down to the individual electrodes to achieve a pure separation as well as efficient collection of the active materials , as shown in Figure 4 (direct recycling with route B).
Positive plate softening (active material appears muddy) will happen before shedding if the battery is regularly undercharged. In the field, a “new” battery that presents itself as being low on capacity can often be conditioned using an external charger and successfully put back into service.
In a corroded battery, much of the current gets lost to resistance (in the form of heat) as the grid wires become exposed and/or disconnected from the active materials.
Disassembly Sequence and Strategies Batteries at their EoL stage are usually collected after being dismantled from EVs and transported to recycling facilities, where valuable active materials and other components can be recycled. Disassembly is an essential step in this recycling process chain.
However, if we made a tear-down analysis of that battery, we would observe positive plates that appear to be in good shape, but the active material looks to be softening and muddy. In a battery suffering from acid stratification, the muddy appearance may be concentrated on the bottom of the plate.
Retrieving cathode active materials from Li-ion battery electrode scraps is a crucial step in direct recycling; however, it presents challenges due to the strong bonds between the active material, carbon black, and binder.
