The rapid evolution of energy storage technology has necessitated the exploration of alternatives to conventional Li-ion batteries. It is driven by the limitations of resource scarcity, safety concerns, and sustainability challenges. This chapter critically discusses the technical, economic, and environmental aspects of emerging battery technologies. While Li-ion batteries are instrumental in powering electronics, electric vehicles, and renewable energy systems, their reliance on limited lithium and cobalt deposits, flammability risks, and recycling hurdles necessitate the development of next-generation solutions. A compelling alternative is solid-state batteries based on non-flammable ceramic, polymer, and glasses. These batteries feature enhanced safety, higher energy density, and improved thermal stability. These parameters satisfy applications in vehicles. Yet, challenges related to manufacturing scalability, interfacial resistance, and cheap production persist. Na-ion batteries gain researchers’ attention due to the low cost of sodium. Despite their lower energy density compared to Li-ion, recent advancements in cathode and anode materials can decrease the performance gap. Another promising avenue is lithium-oxygen and zinc-air systems. The latter offer theoretical energy densities surpassing the ones of Li-ion systems. Oxygen management, electrolyte degradation, and limited cycle life remain limiting barriers. Redox flow batteries, particularly vanadium and organic redox flow systems, provide scalable solutions for long-duration performance, though their bulkiness and lower energy density eliminate their compatibility with tablets and smartphones. Mg , Ca , and Al ions are cheap and offer high theoretical capacities. A slow-ion kinetics must be dealt with in the future. Organic and biodegradable batteries leverage eco-friendly materials and designs, while their current performance limitations restrict them to niche applications. Presently, Li-ion remains the dominant player due to its established infrastructure and cost-effectiveness. Therefore, recycling and sustainability efforts, such as closed-loop recovery systems and ethical sourcing initiatives, are critical in minimizing the ecological footprint of Li. Technological optimizations and machine-learning optimizations are essential for the future of energy storage and portable devices.

Electrolytes are pivotal components of Li-ion batteries. Electrolytes enable ion transport between electrodes. The chemical composition and thermodynamic phase of an electrolyte directly influence performance, safety, and longevity. This chapter discusses challenges and advancements in liquid and solid electrolytes with an accent on their roles in shaping next-generation energy storage systems. Liquid electrolytes, composed of lithium salts dissolved in organic solvents remain the present industry standard, thanks to their desirable ionic conductivity and mature manufacturing infrastructure. Flammability, toxicity, and chemical reactivity under extreme conditions pose risks, such as thermal runaway and fire hazards. In turn, solid electrolytes offer non-flammable alternatives. They exhibit enhanced thermal stability and compatibility with highly energy-dense anodes like lithium metal. Ceramic electrolytes boast promising conductivity and electrochemical stability. Thus far, high production costs and processing challenges hinder the scalability of ceramic alternatives. Polymeric Li-ion electrolytes are flexible and easy to process, yet face limitations, such as relatively low ionic conductivity. Liquid Li-ion electrolytes dominate due to established supply chains and cost-effectiveness. Alternatively, solid electrolytes steadily gain traction amid modern demand for safer and higher-capacity batteries. The synthesis of solid Li-ion electrolytes involves costly processes and requires rare materials. Safety represents a critical driver for solid electrolytes, as they eliminate flammability risks and mitigate lithium dendrite formation. Sustainability and recyclability limitations are common challenges across both electrolyte types. Ionic liquids dissolving lithium salts can be considered to represent the third type of Li-ion electrolyte due to their non-volatility and broad voltage tolerance. Liquid Li-ion electrolytes contribute harshly to environmental pollution due to toxic solvent leakage, whereas solid electrolytes face obvious hurdles in material recovery.
