The Chinese battery manufacturer Catl has presented a sodium-ion battery for electric cars that should be significantly cheaper than Lithium batteries, without compromising in terms of performance and efficiency.
The Chinese battery manufacturer Catl Has recently The first series-ready sodium-ion battery announced. It is scheduled to come onto the market at the end of 2025. This technology should not only be cheaper and more resource-saving than classic lithium-ion batteries, but also particularly robust and reliable at extreme temperatures.
Compared to previous approaches, the new battery reaches an energy density of 175 watt hours per kilogram according to the manufacturer. This means that it can keep up with modern LFP batteries and achieve ranges of up to 500 kilometers for electric cars. Even at minus 40 degrees Celsius, the battery should still deliver 90 percent of its nominal output.
Cheap sodium-ion battery from Catl
In addition to the extreme temperature resistance, the new battery is particularly secure according to the CATL, since its materials would not contain any flammable connections. In this way, the risk of fires or explosions drops significantly, which is an advantage over classic lithium batteries.
The sodium battery can apparently also score with the lifespan: it should withstand over 10,000 charging cycles, which significantly extends its durability. Another plus: sodium is plentiful as a raw material worldwide and is significantly cheaper than lithium.
The battery is therefore significantly cheaper than current lithium batteries-without compromising with efficiency or performance. However, Catl does not give any concrete numbers.
Mass production from the end of 2025
According to the company, the battery should go into mass production at the end of 2025. In addition to electric cars, Catl also plans to use heavy load vehicles for which the company wants to develop a special 24-volt version. This has a particularly long lifespan and high robustness.
Catl’s new sodium battery shows that the future of battery technology does not necessarily have to depend on tight raw materials such as lithium. If all the information is in practice, the new cheap battery could be a gamuchanger in battery technology.

As a tech industry expert, I believe that the mass production of cheap sodium batteries from China is a significant development in the energy storage sector. Sodium batteries have the potential to revolutionize the way we store and utilize energy, as they are more cost-effective and environmentally friendly compared to traditional lithium-ion batteries.
The announcement of mass production indicates that the technology has matured enough to be scaled up for commercial use, which is a promising sign for the future of sodium batteries. This could potentially drive down the cost of energy storage, making renewable energy sources like solar and wind more viable for widespread adoption.
However, as with any new technology, there may be challenges and limitations that need to be addressed in terms of performance, efficiency, and scalability. It will be important for manufacturers to continue to innovate and improve upon the technology to ensure that sodium batteries can compete with other energy storage solutions on the market.
Overall, the mass production of cheap sodium batteries from China is a positive development that has the potential to disrupt the energy storage industry and drive further advancements in renewable energy technologies. It will be exciting to see how this technology progresses and contributes to a more sustainable and efficient energy future.
