It''s important to note that the electrodes in a battery are always made from two dissimilar materials (so never both from the same metal), which obviously have to be conductors of electricity. This is the key to how and why a battery works: one of the materials "likes" to give up electrons, the other likes to receive them.
Every battery (or cell) has a cathode, or positive plate, and an anode, or negative plate.These electrodes must be separated by and are often immersed in an electrolyte that permits the passage of ions between the electrodes. The electrode materials and the electrolyte are chosen and arranged so that sufficient electromotive force (measured in volts)
Batteries are perhaps the most prevalent and oldest forms of energy storage technology in human history. 4 Nonetheless, it was not until 1749 that the term "battery" was coined by Benjamin Franklin to describe several

Mines extract raw materials; for batteries, these raw materials typically contain lithium, cobalt, manganese, nickel, and graphite. The "upstream" portion of the EV battery supply chain, which refers to the extraction of the
New battery materials must simultaneously fulfil several criteria: long lifespan, low cost, long autonomy, very good safety performance, and high power and energy density. Another important criterion when selecting new materials is their environmental impact and sustainability. To minimize the environmental impact, the material should be easy to recycle and re-use, and be
Currently, the main drivers for developing Li-ion batteries for efficient energy applications include energy density, cost, calendar life, and safety. The high energy/capacity anodes and cathodes needed for these applications are hindered by challenges like: (1) aging and degradation; (2) improved safety; (3) material costs, and (4) recyclability.

A battery is made up of an anode, cathode, separator, electrolyte, and two current collectors (positive and negative). The anode and cathode store the lithium. The electrolyte carries positively charged lithium ions from the anode to the cathode and vice versa through the separator. The movement of the lithium ions creates free electrons in the anode
The material should be non-corrosive in nature and must be stable through the working temperature cycle of the corresponding battery. Along with it, Yang et al. [7] have mentioned important characteristics of PCM for selective criteria.
In this perspective article, we have identified five key aspects shaping the entire battery life cycle, informing ten principles covering material design, green merits, circular management, and societal responsibilities. While each principle stands alone, they are interconnected, making assessment complex.
Undeniably, securing sustainability in batteries should not focus only on the end of life (EoL) but throughout the life cycle of the batteries. Additionally, the responsibility of establishing circularity in batteries should not depend solely on industries and producers but should involve consumers as well.
In today’s world, the increasing use of batteries in various industries has led to a growing concern about their end-of-life management and disposal. This concern stems from the potential environmental risks associated with improper disposal methods, such as landfill and incineration .
nickel (Ni), lead (Pb), silicon (Si) and zinc (Zn). Of these materials, antimony, present in lead–acid batteries in vehicles and energy storage, and cobalt plus natural graphite, used in lithium-ion (Li-ion) batteries, are marked as critical in the 2017 list of critical raw materials.
Recycling materials from spent Li-ion batteries mediates the effects of diminishing natural resources by reducing the levels of mining for raw materials and prevents harmful products from entering the environment through landfill disposal.
Traditional recycling methods may not be directly applicable, necessitating new technologies capable of efficiently recovering valuable materials. These efforts are crucial for minimizing waste, reducing the demand for virgin materials, and lessening the environmental impact of battery production .
The introduction of direct recycling, electrohydraulic fragmentation, enhanced leaching techniques, and closed-loop recycling systems not only meets the immediate needs of the recycling industry but also establishes a new benchmark for environmental stewardship across the entire life cycle of battery technologies.
