How Sodium-BasedSolutions are Redefining Security
September 1, 2025
As the adoption of renewable energy systems grows, so does the incidence of battery theft, particularly targeting lithium-ion batteries. The high resale value of lithium and associated metals like cobalt and nickel make these batteries attractive to thieves, posing significant challenges to infrastructure security.
Theft Incidents and Economic Impact
In South Africa, telecommunications companies have reported alarming rates of battery theft. Telkom experienced the theft of at least 1,800 batteries over six months, each valued at approximately R250,000, resulting in losses exceeding R450 million. 1 Similarly, Vodacom reports an average of 62 lithium battery thefts per month across over 120 sites, leading to annual losses of more than R5.35 million.2
These thefts not only incur financial losses but also disrupt essential services. The stolen batteries are often resold or repurposed, and their removal can lead to service outages, affecting communication networks and emergency services.
Sodium-Based Batteries: A Less Attractive Target
Sodium-based batteries offer inherent advantages in theft resistance. Unlike lithium batteries, they do not contain high-value metals, reducing their attractiveness to thieves. The materials used in sodium batteries have low resale value, making them less lucrative targets.
Additionally, sodium batteries are typically larger and heavier than their lithium counterparts, complicating unauthorized removal and transportation. Their design often includes integrated safety features and lower operating voltages, further deterring tampering and unauthorized use.
Enhanced Safety and Reduced Risk
Beyond theft resistance, sodium-based batteries offer improved safety profiles. They are non-flammable and exhibit thermal stability, reducing the risk of fires—a concern with lithium-ion batteries, especially when damaged or improperly handled. This safety aspect is crucial in residential and commercial installations, where battery fires can have catastrophic consequences.
In an era where energy infrastructure security is paramount, sodium-based energy storage systems provide a compelling solution. Their low theft appeal, combined with enhanced safety features, make them ideal for applications where security and reliability are critical. As the energy sector continues to evolve, incorporating sodium-based technologies could significantly mitigate risks associated with battery theft and enhance overall system resilience.
