The Future of Battery Technology: Lithium-Ion vs Sodium-Ion Batteries and New Shipping Regulations

Introduction: The Power Behind Our Connected World

In today's rapidly evolving technological landscape, batteries have become the unsung heroes powering our increasingly connected and environmentally conscious world. From smartphones to electric vehicles, lithium-ion batteries have been at the forefront of this energy revolution. However, with the global lithium-ion battery market expected to surpass $446.85 billion by 2032, we're facing unprecedented challenges in safety, transportation, and environmental impact.

As we approach 2025, a pivotal moment in battery regulation is on the horizon. Global authorities are introducing the most comprehensive updates in a decade, redefining how lithium-ion and emerging sodium-ion batteries are classified and transported. These changes will set the stage for safer, more sustainable energy storage solutions. Whether you're a manufacturer, shipper, or end-user, understanding these new rules is critical to staying competitive and compliant in the global market.

At FreightAmigo, we're committed to helping our clients navigate these changes seamlessly. Our Digital Logistics Platform is designed to adapt to evolving regulations, ensuring that your battery shipments remain compliant and efficient. Let's dive into the details of these changes and how they might affect your business.

The Rise of Sodium-Ion Batteries: A New Contender in Energy Storage

As the demand for energy storage solutions grows, especially in the context of renewable energy, the industry is witnessing a shift towards alternative battery technologies. Sodium-ion batteries have emerged as a promising alternative to lithium-ion batteries. Both types are rechargeable and applicable to everyday technologies, but they have distinct characteristics that set them apart.

Energy Density and Performance

Lithium-ion batteries have long been favored for their high energy density, typically ranging from 150 to 250 Wh/kg. This makes them ideal for applications like electric vehicles and portable electronics, where long usage times and reduced weight are crucial. In contrast, sodium-ion batteries currently offer lower energy densities, usually between 100 to 150 Wh/kg. While this makes them less suitable for compact applications, ongoing advancements in materials science are gradually improving their performance.

Cost and Resource Availability

One of the most significant advantages of sodium-ion batteries lies in the abundance and low cost of sodium compared to lithium. Sodium is widely available in seawater and various mineral sources, making it less susceptible to market fluctuations. On the other hand, lithium extraction can be expensive and environmentally challenging, contributing to higher costs for lithium-ion batteries. As global demand increases, concerns about lithium supply and sustainability continue to grow.

Manufacturing and Environmental Impact

The manufacturing processes for sodium-ion batteries are similar to those of lithium-ion batteries. However, the lower material costs associated with sodium could lead to overall cost reductions in the future, making sodium-ion batteries a more economically viable option, especially for large-scale applications.

From an environmental perspective, lithium-ion batteries have raised concerns due to mining practices, pollution, and recycling challenges. The production and disposal of lithium batteries can have significant ecological impacts. In contrast, sodium-ion batteries benefit from more abundant materials and potentially pose fewer environmental risks. Their development could lead to a more sustainable energy storage solution, particularly if effective recycling technologies are implemented.

At FreightAmigo, we understand the importance of staying ahead of these technological advancements. Our Digital Logistics Solution is designed to accommodate the shipping requirements of both lithium-ion and sodium-ion batteries, ensuring that our clients can adapt to market changes efficiently.

Key Changes to UN Classifications: Preparing for 2025

The emergence of sodium-ion batteries has caught the attention of dangerous goods regulators, resulting in new UN numbers and shipping requirements set to take effect in 2025. These changes will significantly impact how batteries are classified and transported. Here are the key additions:

• UN 3551 - Sodium-ion batteries
• UN 3552 - Sodium-ion batteries packed with/contained in equipment
• UN 3556 - Vehicle, lithium-ion-battery-powered
• UN 3557 - Vehicle, lithium-metal-battery-powered
• UN 3558 - Vehicle, sodium-ion-battery-powered

It's crucial to note that lithium-battery-powered vehicles, such as e-bikes, e-scooters, and any other lithium-battery-powered contraption that can transport people or cargo, will no longer be classified under UN 3171 Battery-Powered Vehicles. Instead, they must be classified under UN 3556, UN 3557, or UN 3558, depending on the battery chemistry.

Given the significant impact this change will have on supply chains for lithium-battery-powered vehicles, regulators have provided a three-month transition period beginning January 1, 2025. Effective March 31, 2025, UN 3171 will only be applicable to battery-powered vehicles that are powered by battery chemistries other than lithium, such as traditional lead-acid batteries.

At FreightAmigo, we're committed to helping our clients navigate these new classifications seamlessly. Our Digital Logistics Platform will be updated to reflect these changes, ensuring that your shipments are correctly classified and compliant with the new regulations.

Updated State of Charge (SoC) Requirements: A New Era of Safety

Another significant change coming into effect is the updated State of Charge (SoC) requirements for lithium-ion batteries. Previously, only loose lithium-ion batteries were subject to a SoC restriction of no more than 30% of their rated capacity when transported on airplanes. However, starting January 1, 2026, these SoC requirements will apply to a broader range of lithium-ion battery products.

According to packing instructions 952, 966, and 967 of the International Air Transport Association Dangerous Goods Regulations (IATA DGR), shippers will need to ensure their lithium battery products conform to the following restrictions:

From January 1, 2026 (UN 3556, UN 3557, UN 3558, UN3481)

• Vehicles with batteries >100 Wh: No more than 30% of rated capacity (mandatory), approval needed for higher SoC
• Vehicles with batteries ≤100 Wh: No more than 30% of rated capacity (recommended)
• Lithium-ion batteries packed with equipment > 2.7Wh (UN 3481 PI 966): No more than 30% of rated capacity (mandatory), approval needed for higher SoC
• Lithium-ion batteries contained in equipment (UN 3481 PI 967): No more than 30% of rated capacity (recommended)

This 30% charge restriction represents a major regulatory update for businesses handling lithium-battery-powered vehicles, as well as those that move lithium-ion batteries packed with equipment, such as charging cases for bluetooth earbuds.

At FreightAmigo, we understand the complexities these new regulations bring. Our Digital Logistics Solution is designed to help you manage these new SoC requirements effectively, ensuring your shipments remain compliant while optimizing your supply chain efficiency.

The Impact on Businesses and Supply Chains

The 2025 and 2026 lithium-ion battery regulation changes represent a significant turning point for the transportation and storage of batteries. These changes will ensure greater safety and sustainability as global reliance on energy storage continues to grow. However, they also present challenges that businesses across industries must address quickly and strategically.

For manufacturers, these changes may require adjustments to production processes and packaging methods. Shippers will need to update their documentation and handling procedures to comply with the new classifications and SoC requirements. End-users, particularly those in industries heavily reliant on battery-powered equipment, may need to reassess their inventory management and charging practices.
