Overview of Metal-Ion Battery Recycling Methods
Metal-ion batteries (MIBs), particularly lithium- and sodium-ion ones (LIBs and SIBs, respectively), are an essential part of portable and stationary electronics due to their energy density characteristics and long-term cycling ability. The expected growth of the MIBs market unavoidably leads to the generation of tons of spent batteries, this in turn dictates the necessity of a proper life cycle management of used cells and packs.

Electromagnetic Fields Exposure
In different situations, electromagnetic fields (EMF) are consumed every day in several sociable purposes. Additionally, they are employed securely in medical treatments. Conversely, when these fields are operated inadvertently, it can crop unfavorable outcomes. These consequences are intimately linked to the type of the EMF and the exposed substance. The strength of the field as well as its frequency typify EMF, whereas the physical and geometric properties describe matter.

Electrocatalytic Reactions for Converting CO2 to Value-Added Products
Carbon dioxide (CO2) emissions are an important environmental issue that causes greenhouse and climate change effects on the earth. Nowadays, CO2 has various conversion methods to be a potential carbon resource, such as photocatalytic, electrocatalytic, and photo-electrocatalytic. CO2 conversion into value-added products has many advantages, including facile control of the reaction rate by adjusting the applied voltage and minimal environmental pollution. The development of efficient electrocatalysts and improving their viability with appropriate reactor designs is essential for the commercialization of this environmentally friendly method.

Energy Efficiency in a Global Context
Energy efficiency is, in principle, a simple idea: an output of human value, for example, vehicle-km traveled, divided by the needed input energy. Efficiency improvements are regarded as an important means of mitigating not only climate change, but also other environmental problems. Much has been written about energy efficiency, but it is mainly concerned with means for improving efficiency, or barriers to implementing higher energy efficiency. In contrast, this entry argues that the concept of energy efficiency needs to be broadened, both conceptually to include ethical considerations, and spatially, to include distant as well as local impacts.

Electricity Day-Ahead Market Conditions and Market Price Forecasting
Participants in deregulated electricity markets face risks from price volatility due to various factors, including fuel prices, renewable energy production, electricity demand, and crises such as COVID-19 and energy-related issues. Price forecasting is used to mitigate risk in markets trading goods which have high price volatility. Forecasting in electricity markets is difficult and challenging as volatility is attributed to many unpredictable factors.

Lithium-Ion Battery Disassembly Processes for Efficient Recycling
Recycling plays a crucial role in achieving a sustainable production chain for lithium-ion batteries (LIBs), as it reduces the demand for primary mineral resources and mitigates environmental pollution caused by improper disposal. Disassembly of the LIBs is typically the preliminary step preceding chemical recovery operations, facilitating early separation of components consisting of different materials. Despite that extensive research has been conducted on the chemical processes involved in the recycling of LIBs, systematic studies on disassembly processes in the recycling process are relatively scarce.
