[PDF Version]Recycling batteries is a complex process that involves several stages, each critical for efficient material recovery and environmental sustainability. The primary methods include mechanical, pyrometallurgical, and hydrometallurgical processes, each suited to different components and types of batteries, as follows.
Lithium-ion batteries recycling processes The three major methods of recycling LIBs are pyrometallurgical, hydrometallurgical, and direct recycling processes. Pyro- and hydrometallurgical processes are chemical processes, while direct recycling is a physical process .
Enhanced leaching techniques, such as ultrasonically assisted leaching, improve the efficiency of metal recovery using eco-friendly solvents. Additionally, closed-loop recycling systems, which aim to recover and reuse all battery components, are being developed to minimize waste and reduce the need for new raw materials.
Despite these challenges, direct recycling is particularly promising for reducing the overall environmental impact of battery disposal. The complexities associated with the diverse chemistries, designs, and sizes of LIBs further complicate the recycling process, often necessitating manual sorting and disassembly.
Typical direct, pyrometallurgical, and hydrometallurgical recycling methods for recovery of Li-ion battery active materials. From top to bottom, these techniques are used by OnTo, (15) Umicore, (20) and Recupyl (21) in their recycling processes (some steps have been omitted for brevity).

In the first part of this paper, we review the developments which led to the present state-of-the-art in the surface passivation of today's industrially predominant dopant-diffused crystalline silicon (c-Si) s. ••We review the surface passivation of dopant-diffused crystalline silicon (. The steadily increasing bulk carrier lifetimes of crystalline silicon (c-Si) wafers for the application to commercial c-Si solar cells makes recombination at the cell surfaces and at the contac. In this review, we do not intend to provide a complete historic overview of the evolution of the various surface passivation schemes. For such an overview, the reader is referred to the existing co. 3.1. Definition of selectivityThe above discussion showed that carrier-selective layers should allow one polarity of charge carriers to pass to the metal and should block the. 4.1. Poly-Si layers on oxideExcellent carrier-selective contacts based on hydrogenated amorphous silicon (a-Si:H) layers are well known and have recently led to th.
[PDF Version]An efficiency (22.01%) of MoO x -based crystalline silicon solar cells Effective surface passivation is pivotal for achieving high performance in crystalline silicon (c -Si) solar cells. However, many passivation techniques in solar cells involve high temperatures and cost.
We review the surface passivation of dopant-diffused crystalline silicon (c-Si) solar cells based on dielectric layers. We review several materials that provide an improved contact passivation in comparison to the implementation of dopant-diffused n+ and p+ regions.
Eventually, by employing sulfurization in hole-selective contacts, remarkable efficiencies of 19.85% and 22.01% are attained for NiO x - and MoO x -based passivating contact c -Si solar cells, respectively. Our work highlights a promising sulfurization strategy to enhance surface passivation and hole selectivity for dopant-free c -Si solar cells.
To further promote the surface passivation and hole selectivity of the rear contact for high-performance p -Si solar cells, an additional ultrathin Al 2 O 3 film was employed as the passivation interlayer.
In general, the efficiency potential of solar cells with carrier-selective passivation layers is much higher compared to conventionally diffused c-Si cells, because recombination at the metal/c-Si contact is more effectively suppressed.
Due to the simple deposition by spin- or spray-coating techniques from a liquid dispersion under ambient environment and the fact that PEDOT:PSS is a very cost-effective material, it is a promising low-cost candidate for contact passivation in future generations of c-Si solar cells.
Lithium–silicon batteries are lithium-ion batteries that employ a silicon-based anode, and lithium ions as the charge carriers. Silicon based materials, generally, have a much larger specific capacity, for example, 3600 mAh/g for pristine silicon. The standard anode material graphite is limited to a maximum theoretical capacity of 372 mAh/g for the fully lithiated state LiC6. The first laboratory experiments with lithium-silicon materials took place in the early to mid 1970s. Silicon. The lattice distance between silicon atoms multiplies as it accommodates lithium ions (lithiation), reaching 320% of the original volume. The expansion causes large anisotropic stresses to occur within the electrode materia. Besides the well recognized problems associated with large volume expansion, for example cracking the SEI layer, a second well recognized issue involves the reactivity of the charged materials. Since charged silicon is a lithium.
