Sodium ion batteries hold a lot of promise. They are energy dense, non-flammable and work well in colder temperatures, and sodium is cheap and abundant. In addition, sodium-based batteries are more environmentally friendly and even cheaper than the lithium-ion batteries that are currently being replaced. The performance of the sodium-ion battery is limited by poor durability, but it is getting better.

Sodium-ion battery breakthrough
A research team at the U.S. Department of Energy’s Pacific Northwest National Laboratory (PNNL) has developed a sodium ion battery with a significantly longer lifespan. The findings, published in the journal Nature Energy, offer a promising recipe for a battery that could one day power electric vehicles and store solar energy.
The researchers shifted the ingredients that make up the battery’s liquid core. This shift avoids the performance issues that have plagued previous sodium-based batteries.
PNNL lead author Jiguang (Jason) Zhang, a battery technology pioneer with more than 23 patented inventions in energy storage technology, said:
Here we have fundamentally demonstrated that sodium ion batteries can be a long-lasting and environmentally friendly battery technology.
The right salt
As PNNL explains, the electrolyte in batteries is the circulating “blood” that keeps the energy flowing. An electrolyte is formed by dissolving salts in solvents, resulting in charged ions that flow between the positive and negative electrodes. Over time, the electrochemical reactions that keep the energy flowing become slow and the battery can no longer charge. In current sodium-ion battery technologies, this process occurs much faster than in lithium-ion batteries.
The PNNL team attacked this problem by switching out the liquid solution and the type of salt passing through it to create a new electrolyte recipe.
For the first time, researchers significantly extended the number of charge cycles (300 or more) of a coin-sized battery in laboratory tests with minimal volume loss (>90% retained).
As PNNL explains, the current electrolyte recipe for sodium-ion batteries causes the protective film on the negative end (anode) to dissolve over time. This film is critical because it allows sodium ions to pass through while maintaining battery life.
Technology created by PNNL stabilizes this protective film. The new electrolyte also creates an ultra-thin protective layer on the positive pole (cathode), which contributes to the additional stability of the entire device.
Nonflammable technology
The sodium ion technology, newly developed by PNNL researchers, uses a naturally occurring fire extinguishing solution that is also resistant to temperature changes and can operate at high voltages. One of the keys to this feature is the ultra-thin protective layer that forms on the anode. This ultra-thin layer remains stable once formed, providing the long cycle life described in the research paper.
Sodium ion technology still lags behind lithium in terms of energy density. But it still has its own unique advantages, such as resistance to temperature changes, stability and long service life. These advantages will prove valuable in the future for certain light electric vehicles and even grid energy storage.
