Nickel, known for its high energy density, plays a crucial role in positive electrodes, allowing batteries to store more energy and enabling longer travel ranges between charges—a significant challenge in widespread EV adoption (Lu et al., 2022). Cathodes with high nickel content are of great interest to researchers and battery manufacturers
Electric current is generated when lithium ions migrate from the negative electrode (anode) to the positive electrode (cathode) through the electrolyte during discharge. Reversing this process results in intercalation of lithium ions
where Δ n Li(electrode) is the change in the amount (in mol) of lithium in one of the electrodes.. The same principle as in a Daniell cell, where the reactants are higher in energy than the products, 18 applies to a lithium-ion battery; the low molar Gibbs free energy of lithium in the positive electrode means that lithium is more strongly bonded there and thus lower in

At higher charge cutoff voltages, the positive electrode materials are destabilized, leaving the material more susceptible to chemical and electrochemical leaching of the electrolyte (Figure 1D). The dissolution of transition metal cations only accounts for a mild or negligible capacity loss of the positive electrode materials [47,48].
In addition, considering the growing demand for lithium and other materials needed for battery manufacturing, such as [3], [27], [28], it is necessary to focus on more sustainable materials and/or processes and develop efficient, cost-effective and environmental friendly methods to recycle and reuse batteries, promoting a circular economy approach and
Na-ion batteries are operable at ambient temperature without unsafe metallic sodium, different from commercial high-temperature sodium-based battery technology (e.g., Na/S5 and Na/NiCl 2 6 batteries).

Subsequently, the insertion of lithium into a significant number of other materials including V 2 O 5, LiV 3 O 8, and V 6 O 13 was investigated in many laboratories. In all of these cases, this involved the assumption that one should assemble a battery with pure lithium negative electrodes and positive electrodes with small amounts of, or no, lithium initially.

Electric current is generated when lithium ions migrate from the negative electrode (anode) to the positive electrode (cathode) through the electrolyte during discharge. Reversing this process results in intercalation of lithium ions back into the anode and their removal from the cathode to produce the charged state.
