Lithium-ion batteries are the state-of-the-art electrochemical energy storage technology for mobile electronic devices and electric vehicles. Accordingly, they have attracted a continuously increasing interest in academia and industry, which has led to a steady improvement in energy and power density, while the costs have decreased at even faster pace.
A new class of PFAS (bis-perfluoroalkyl sulfonamides) used in lithium-ion batteries have been released to the environment internationally. This places lithium-ion batteries at the nexus of CO2

Gas saturation matters: Saturation of lithium-ion battery electrolytes with various gases is systematically investigated. Significant differences in cell performance, C-rate capability and charge transfer processes are identified between different gases.
It would be unwise to assume ''conventional'' lithium-ion batteries are approaching the end of their era and so we discuss current strategies to improve the current and next generation systems
Solid-state batteries have a more substantial environmental impact during the production phase, approximately 27 % higher than similar lithium batteries, with NCM outpacing LFP. However, in the usage phase, NCM batteries, due to their unique structure, significantly mitigate energy losses compared to LFP batteries.
In 1995, Rudolph et al. collected the Raman spectra from LiCl saturation concentrations to more dilute solutions at room temperature, where the new band at 255 cm −1 corresponds to the Li─O symmetric stretching of Li(OH 2) 4 +.

The rechargeable lithium metal batteries can increase ∼35% specific energy and ∼50% energy density at the cell level compared to the graphite batteries, which display great potential in portable electronic devices, power tools and transportations. 145 Li metal can be also used in lithium–air/oxygen batteries and lithium–sulfur batteries to improve the capacity
The growth in EV sales is pushing up demand for batteries, continuing the upward trend of recent years. Demand for EV batteries reached more than 750 GWh in 2023, up 40% relative to 2022, though the annual growth rate slowed slightly compared to in 2021‑2022. Electric cars account for 95% of this growth. Globally, 95% of the growth in battery
Over the past 25 years, the number of new trade measures targeting batteries, solar PV, EVs, wind turbines and electrolysers has increased steadily.

Significant differences in cell performance, C-rate capability and charge transfer processes are identified between different gases.
In a secondary battery, energy is stored by using electric power to drive a chemical reaction. The resultant materials are “richer in energy” than the constituents of the discharged device .
Figure 19 demonstrates that batteries can store 2 to 10 times their initial primary energy over the course of their lifetime. According to estimates, the comparable numbers for CAES and PHS are 240 and 210, respectively. These numbers are based on 25,000 cycles of conservative cycle life estimations for PHS and CAES.
Charge–discharge characteristics, C-rate capability, efficiencies and EIS are shown to give a detailed understanding and quantification of gas impacts. The study thus paves the road for future tailoring of electrolyte pretreatment of lithium-ion batteries to increase performance and lifetime.
These new devices believed to result in enhanced performance i.e., energy densities, cycling, power capabilities and efficiencies. Other factors require considerations include operational safety, environmentally friendliness, sustainability of sourcing of battery components and end of life consideration i.e., reusing and recycling.
A matter of concentration: The latest ground-breaking advances and strategies of using concentrated electrolyte for aqueous batteries, are discussed. Emphasis is placed on aqueous batteries for lithium and post-lithium chemistries, with improved energy density, resulting from the unique properties of salt-concentrated electrolytes.
