On the other hand, a sodium-ion battery counts on an aspect– salt– that you can discover in salt and ocean water.
Amongst the other advantages, sodium-ion batteries carry out much better than lithium-ion batteries in severe cold. CATL has stated its brand-new battery operates in temperature levels as low as -40 ° Fahrenheit.
A sodium-ion battery has much lower threat of fire. When lithium-ion batteries sustain damage, it can result in “thermal runaway,” which activates a hazardous and hazardous fire.
The procedure of making sodium-ion batteries resembles that of lithium-ion batteries, or a minimum of comparable adequate that business can move existing assembly lines without needing to invest greatly on retooling.
Sodium-ion batteries have some downsides. The huge one is low energy density compared to lithium-ion. As an outcome, an EV working on a sodium-ion battery will go fewer miles per charge than a lithium-ion battery of the exact same size.
“That is simply what nature has actually provided us,” Srinivasan stated. “From a physics viewpoint, salt batteries naturally have lower energy density than lithium batteries.”
A normal sodium-ion battery has an energy density of about 150 watt-hours per kg at the cell level, he stated. Lithium-ion batteries can vary from about 180 to almost 300 watt-hours per kg.
I asked Srinivasan what he makes from CATL’s claim of a sodium-ion battery with 200 watt-hours per kg.
“We tend to be hesitant of press release from business,” he stated. He defined that his remark uses to all battery business.

The nationwide laboratories’ effort has a five-year timeline, with an objective of establishing sodium-ion batteries with energy densities that match or go beyond those these days’s iron phosphate-based lithium-ion batteries. Scientists would do this by discovering numerous effectiveness in style and products.
The job is taking place together with the laboratories’ continuous work to establish and enhance other type of batteries.
Lithium-ion batteries control today’s market. This year, international production of lithium-ion batteries had to do with 1,500 gigawatt-hours, and production of sodium-ion batteries was 11 gigawatt-hours, or less than 1 percent, according to Benchmark Mineral Intelligence.
