Back to the Future of Sodium-Ion Energy Storage and Automotive mobility

"Sine Sale, non est Vita". Sea salt has a long centenary history as a valuable commodity, used at first as money in ancient civilizations, where it was traded and hoarded due to its essential role in food preservation and flavour enhancement. Ancient Romans even referred to soldiers' salaries as "salarium," derived from the Latin word for salt, while beyond its historical economic significance, salt has been crucial for food preservation methods, such as curing and pickling methods, as ancient as "Garum" preservation method of fresh fish. Additionally, with modernity and technology, from sea salt have been developed and produced saline solutions already utilized in ordinary battery packs to start-off car engines and lights, illustrating salt's versatile applications throughout history and into modern technology. The development of new-generation batteries is a determining factor in the future of energy storage, which is key to decarbonization and the energy transition in the face of climate change challenges. Storing renewable energy makes renewable energy production more flexible and ensures its integration into the system. Since their emergence in 1991, lithium batteries have dominated the energy storage sector. However, this leadership has led to a significant increase in demand for lithium, raising concerns about potential supply shortages, price increases, and delays. In recent years, battery manufacturers and the automotive industry have been exploring alternative raw materials to lithium for the manufacture of energy storage systems. One of the most promising options is the sodium-ion battery. With the relative abundance of sodium and its low cost, sodium-ion batteries are positioned as a revolutionary force in renewable energy storage. What Are Sodium-Ion Batteries and How Do They Work? Sodium-ion batteries are rechargeable batteries that function similarly to lithium batteries, but use sodium ions (Na+) to carry the charge instead of lithium ions (Li+). Sodium, a soft alkaline metal, is abundant in nature, and found in sources such as sea salt and the earth's crust. The operation of sodium-ion batteries resembles that of lithium-ion batteries due to the chemical similarities of the two elements. Despite their potential, sodium batteries have historically faced challenges. Their heavier raw material and lower voltage lead to reduced energy density, impacting the range of electric vehicles (EVs). However, recent innovations, particularly from Korean researchers, have addressed these shortcomings by developing high-performance sodium-based EV batteries. Innovations from Korean Research Researchers at the Korea Advanced Institute of Science and Technology (KAIST) have created a hybrid sodium battery that combines anode materials from conventional batteries with cathodes derived from supercapacitors. This novel design includes iron sulfide particles embedded in carbon and graphene, enhancing both energy storage capacity and conductivity. In tests, this sodium battery has demonstrated impressive results, achieving an energy density of up to 250 Wh/kg and the ability to charge up to 100 times faster than existing lithium-ion batteries. After 5,000 charge and discharge cycles, the battery maintained its efficiency and performance, suggesting a long lifespan without significant degradation—a stark contrast to lithium-ion batteries that often begin to decline after 500 cycles. Advantages and Disadvantages of Sodium-Ion Batteries Sodium-ion batteries offer several advantages: Cost-Effectiveness: They are generally cheaper to produce than lithium batteries due to lower raw material costs. Environmental Benefits: Sodium-ion batteries are considered more environmentally friendly, as sodium is abundant and easier to source than lithium, cobalt, and nickel, which often require extensive mining processes. Safety: Sodium-ion batteries are less prone to thermal runaway compared to lithium-ion batteries, enhancing safety in various applications. Sodium-ion batteries offer a notable safety advantage over lithium-ion counterparts, as they are non-flammable and operate with more stable chemistry. Unlike lithium, sodium does not react as aggressively with air or moisture, reducing risks of overheating and combustion. This enhanced safety profile makes sodium-ion technology particularly appealing for applications in electric vehicles and energy storage, where durability and reduced fire hazards are critical. Additionally, the lower environmental impact and wider availability of sodium contribute to its potential as a safer, sustainable alternative. Energy Density: Sodium-ion batteries currently developed have an improved energy density compared to lithium-ion batteries, which improves the driving range of electric vehicles. Charging Time: research developments have improved the charging speed of sodium-ion batteries making them faster compared to their lithium counterparts.
