During the initial cycling of lithium-ion batteries, the generation of SEI at the electrode-electrolyte interface and the occurrence of irreversible side reactions consume the active lithium, resulting in irreversible loss of volume (ICL), which may also be accompanied by electrode volume changes and structural collapse. Addressing these challenges has become critical, and pre-lithiation with additional lithium has emerged as a key way to improve battery performance. Hence, this review comprehensively analyzes and summarizes the causes of ICL in lithium-ion batteries, and systematically discusses various prelithiation methods and mechanisms of different electrode structures, especially electrodes. Moreover, we discuss the importance of developing effective electrolyte, separator, and binder pre-lithiation technologies to improve ionic conductivity and battery life. The effectiveness of each strategy in improving initial capacity and cycling stability, while addressing compatibility issues and minimizing potential side effects, is evaluated to inform the future development and large-scale application of pre-lithiation technology.

The global lithium-ion battery recycling capacity needs to increase by a factor of 50 in the next decade to meet the projected adoption of electric vehicles. During this expansion of recycling capacity, it is unclear which technologies are most appropriate to reduce costs and environmental impacts. Here, we describe the current and future recycling capacity situation and summarize methods for quantifying costs and environmental impacts of battery recycling methods with a focus on cathode active materials.

We report a silicon anode for lithium-ion batteries consisting of a layer of 100% nanotubes directly bonded to copper foil. The process involved silicon deposition on a sacrificial zinc oxide nanorod film and removal of zinc oxide to produce a nanotube film directly on thin copper foils. The thickness of resulting films ranged from 9 to 20 μm with Si nanotubes having diameters of 200-400 nm and lengths of 2-10 μm.

The yolk-shell architecture offers a promising solution to the challenges of silicon (Si) anodes in lithium-ion batteries (LIBs), particularly in addressing the significant volume changes that occur during charge and discharge cycles. However, traditional construction methods often rely on sacrificial templates and acid or alkali etching, which limits industrial applicability. In this work, we successfully constructed a silicon/carbon (Si/C) composite with a multicore yolk-shell structure using scalable spray drying technology and in-situ growth of metal-organic frameworks (MOFs) at room temperature.

Li-ion capacitors (LICs) integrate the desirable features of lithium-ion batteries (LIBs) and supercapacitors (SCs), but the kinetic imbalance between the both electrodes leads to inferior electrochemical performance. Thus, constructing an advanced anode with outstanding rate capability and terrific redox kinetics is crucial to LICs. Herein, heterostructured ZnS/SnS2 nanosheets encapsulated into N-doped carbon microcubes (ZnS/SnS2@NC) are successfully fabricated.
