As Hurricane Helene continues to batter the southeastern United States, electric vehicle (EV) owners face unique challenges and risks. The powerful storm, which has already caused widespread flooding and significant damage, poses a particular danger to EVs that may be submerged in saltwater.
- EVs submerged in saltwater during hurricanes can catch fire due to short circuits and thermal runaway.
- Florida Governor Ron DeSantis advised EV owners to move their cars to higher ground before Hurricane Helene.
- The NHTSA has been researching EV risks since Hurricane Sandy, but comprehensive statistics on fires are still limited.
- EV manufacturers recommend moving submerged cars away from structures until they can be inspected for safety.
Florida Governor Ron DeSantis urged EV owners to move their vehicles to higher ground before Hurricane Helene’s arrival. Although rare, there have been instances of electric vehicles catching fire after being inundated by saltwater. The National Highway Traffic Safety Administration (NHTSA) has been researching this issue since Hurricane Sandy in 2012, but detailed statistics remain scarce.
NBC reported that during Hurricane Ian two years ago, the batteries of up to 5,000 EVs were compromised, with 36 catching fire. Similar incidents occurred after Hurricane Idalia last year, prompting concerns about potential fires during Hurricane Helene.
Tom Barth, chief of the special investigations branch of the NTSB’s office of highway safety, explained the risk: “If the saltwater is able to bridge the gap between the positive and negative terminals of the battery, it can cause a short circuit.” This can lead to a chain reaction called thermal runaway, where the heat spreads between different cells in the battery pack.
Carmakers design their batteries to prevent such issues, incorporating separations and insulation barriers between cells and measures to keep moisture out. However, prolonged submersion in standing water can overcome these moisture seals, leading to potential fires.
As reported by ABC News, Tesla and other EV manufacturers advise moving submerged vehicles at least 50 feet away from structures or anything combustible until they can be inspected by a mechanic. Keeping EVs out of standing water is the best way to avoid fires.

Why Silver Makes a Better Battery: The Future of Energy Storage
In the ongoing quest for more efficient and longer-lasting energy storage solutions, researchers are increasingly turning to silver as a potential game changer in battery technology. While lithium-ion batteries remain dominant in the market, silver offers several advantages that could lead to the development of superior batteries with faster charging times, greater energy density, and longer lifespans. Here’s why silver may pave the way for the next generation of batteries.
Superior Conductivity
One of the primary reasons silver is considered for battery development is its exceptional electrical conductivity. Silver is the most conductive element of all metals, allowing electrons to flow more freely compared to other materials used in batteries, such as copper or aluminum. This high conductivity can lead to faster charging and discharging times, making silver-based batteries more efficient. When applied to electric vehicles (EVs) or portable electronics, this means reduced charging times and greater convenience for consumers.
Greater Energy Density
Another key advantage of silver in batteries is its potential to increase energy density. Energy density refers to the amount of energy a battery can store relative to its size or weight. Higher energy density means that a battery can power a device for longer periods without increasing its size, making it ideal for smartphones, laptops, and electric vehicles. Silver-zinc batteries, in particular, are known for their high energy density, offering up to 40% more power than traditional lithium-ion batteries of the same size. This could revolutionize industries like electric vehicles, where battery weight and size are critical concerns.
Enhanced Safety and Stability
Safety is a major concern when it comes to batteries, especially lithium-ion technology, which can overheat or even catch fire under certain conditions. Silver-based batteries, however, are more stable and resistant to thermal runaway, a dangerous chain reaction that occurs in overheated batteries. Silver’s excellent thermal conductivity helps dissipate heat more effectively, reducing the risk of overheating. This makes silver batteries a safer alternative, particularly for high-performance applications like electric vehicles, drones, and military equipment.
Longer Lifespan
Battery longevity is a key factor influencing consumer satisfaction and the overall cost-effectiveness of energy storage solutions. Silver-based batteries, particularly those that incorporate silver oxide or silver-zinc chemistries, tend to have longer lifespans compared to traditional lithium-ion batteries. These chemistries are less prone to degradation over time, allowing the batteries to retain their capacity after numerous charge cycles. For industries where battery replacement is costly or difficult, such as aerospace or remote installations, silver’s longevity offers a significant advantage.
Environmental Considerations
With the growing demand for sustainable and environmentally friendly technologies, the environmental impact of battery production is coming under scrutiny. Silver, though more expensive than other materials, is highly recyclable. Silver-based batteries can be recycled with a higher recovery rate than lithium-ion batteries, which often require complex recycling processes that are less efficient and more harmful to the environment. Additionally, the extraction of silver is less environmentally damaging compared to lithium mining, which can lead to water contamination and habitat destruction.
Challenges to Overcome
While silver offers numerous advantages as a battery material, several challenges must be addressed before it can become a mainstream option. The primary obstacle is cost. Silver is significantly more expensive than other materials currently used in battery production, such as lithium or copper. This makes large-scale adoption difficult, especially in price-sensitive markets like consumer electronics or electric vehicles.
However, ongoing research into optimizing silver’s use in batteries could help bring costs down. By reducing the amount of silver required or combining it with other materials, scientists aim to make silver-based batteries more economically viable. Additionally, as demand for high-performance, fast-charging batteries grows, the premium cost of silver may become justifiable for certain high-end applications, like aerospace, military, or luxury electric vehicles.
The Future of Silver Batteries
Silver’s unique properties offer a tantalizing glimpse into the future of battery technology. As industries continue to seek more efficient, safer, and environmentally friendly energy storage solutions, silver-based batteries could play a critical role in powering everything from smartphones to electric cars and renewable energy grids. While cost remains a barrier to widespread adoption, advancements in materials science and recycling technologies could make silver a key component in the next generation of batteries. In the quest for better energy storage, silver’s potential is too promising to ignore.
