Changan’s black sedan sped down an icy track in northern China. Its tire burst at 95 kilometers per hour. The temperature sat at minus 32 degrees Celsius. Yet the car coasted to a stop. No spin. No crash. This February demonstration highlighted more than winter driving. It signaled the arrival of mass-produced electric vehicles powered by sodium-ion batteries.
CATL supplied the cells for Changan’s Nevo A06. The model reaches dealerships in China this year. Its 45-kilowatt-hour pack delivers over 400 kilometers of range on local test cycles. And it holds 90 percent capacity at minus 40 degrees Celsius. Safety tests prove the point. Technicians sawed a cell in half. It kept powering a light bulb. No fire. No thermal runaway.
These details come from New Scientist. The July 7, 2026, article by Alec Luhn captures a technology long dismissed as too heavy for vehicles. Sodium weighs three times more than lithium. Early cells struggled with energy density. But generations of improvement have changed the math. CATL now reports 175 watt-hours per kilogram. That matches entry-level lithium iron phosphate packs in budget EVs from Tesla and others.
But performance tells only part of the story. Sodium comes from table salt. Abundant. Cheap. No mining bottlenecks like lithium. Processing demands less energy and carries a smaller carbon footprint. China dominates lithium refining. Geopolitical tensions could disrupt supplies. Sodium sidesteps that risk. Its ions move more freely in cold electrolytes. They generate less heat during reactions. Fire risk drops. Cooling systems shrink. Costs fall further.
Moritz Schütte at RWTH Aachen University studied one sodium-ion cell from Chinese maker Hina. It rivaled Tesla batteries on most metrics. The pack weighed one-third more. Still, Schütte sees rapid progress. “The ramp-up of the sodium-ion batteries is fast,” he told New Scientist. “That means the production cost is getting lower and lower. The materials are getting more advanced with every generation. We don’t know where it ends, at which energy density.”
Maria Crespo-Ribadeneyra at Queen Mary University of London takes a broader view. “This is just the start of the battery revolution, in which we are going to see a plethora of new batteries coming to the market and targeting special segments,” she said in the same New Scientist piece. “Sodium is the pioneer that can prove that a world beyond lithium is possible.” Her point lands. Different applications need different chemistries. High-end EVs keep lithium for range. Budget cars, commercial fleets, and stationary storage turn to sodium.
Elliot Richards watched the Changan launch. The Shanghai-based EV vlogger calls sodium the “lithium killer.” He spoke to New Scientist. “We’re all underestimating probably how much this will impact everyone’s daily lives. It’s going to be a lot cheaper to own an EV than a combustion car; it’s going to be a lot cheaper to get batteries into your home; it’s going to be a lot cheaper for the energy provider to deliver energy to your house.”
Commercial momentum builds fast. CATL began shipping its Naxtra sodium-ion cells this summer. Large-scale deployments across vehicles, energy storage, and industrial uses start in 2026. Cumulative shipments could reach one gigawatt-hour by year-end. The company unveiled a grid-specific cell at a Beijing expo in April. Capacity exceeds 300 amp-hours. Round-trip efficiency hits 97 percent. Cycle life surpasses 15,000. Operating range spans minus 40 to 70 degrees Celsius. The cell shares enclosures with CATL’s lithium products. Mixing chemistries becomes simple. IEA noted these advances in a February 2026 commentary. It highlighted CATL’s second-generation cells and confirmed 2026 rollout plans.
BYD broke ground on its first sodium-ion plant in 2024. The facility targets EVs, grid storage, and forklifts. Hina already powered early sodium EVs in China. Smaller producers follow. Yet scaling outside China proves difficult. LG Energy Solution opened a pilot line in Nanjing. Natron Energy, a U.S. developer, shut down operations and halted factory plans. The IEA report flags supply-chain gaps and cost gaps with lithium iron phosphate at current lithium prices.
Grid storage offers the clearest early win. Energy density matters less here. Cost, safety, and longevity dominate. A massive sodium station the size of 15 soccer fields operates in China since 2024. Peak Energy flipped the switch on America’s first grid-scale sodium system near Denver in late 2025. The 3.5-megawatt-hour installation needs no active cooling. That cuts expense and complexity. General Motors partnered with Peak through its venture arm. GM develops purpose-built sodium cells at its Wallace Battery Cell Innovation Center in Warren, Michigan. Kurt Kelty, GM’s vice president of battery, propulsion, and sustainability, explained the appeal in a GM news release on June 9, 2026. “It is delivering reliable, affordable power over long periods of time in real-world conditions. That is what makes sodium-ion battery technology so compelling.”
Peak signed a deal with Jupiter Power for up to 4.75 gigawatt-hours between 2027 and 2030. Value could exceed $500 million. A pilot agreement with RWE Americas followed in March 2026. In Europe, Swiss firm Phenogy commissioned a 1-megawatt-hour sodium system near Bremen, Germany. It sits beside solar panels and powers fast chargers. Bonnen Batteries reviewed these projects in a 2026 comparison. Sodium shines for home storage, data centers, and renewable balancing. Weight penalties disappear when systems sit fixed.
Alsym Energy pushed sodium iron pyrophosphate chemistry for grid use. Its white paper, hosted by Volta Foundation in May 2026, argues this variant offers superior safety and cost in all environments. Unigrid, another U.S. player, eyes international off-takers. CleanTechnica reported the surge in January. Transportation remains secondary. Yet hybrids could pair sodium for cold-weather bursts with lithium for range.
Challenges persist. Sodium cells still cost more than lithium iron phosphate in many scenarios. Energy density trails top lithium chemistries. Production volumes remain tiny compared with lithium-ion. But 2026 marks a pivot. CATL’s factory output, GM’s prototypes, Peak’s installations, and policy pushes for supply-chain diversity accelerate adoption. Lithium stays king for premium vehicles. Sodium claims budget EVs, extreme climates, and stationary muscle.
So the battery mix diversifies. Each use case gets its chemistry. Sodium proves the model. Its ions flow. Its costs drop. Its safety record holds. The Changan sedan did not spin on ice. The grid batteries keep running without cooling fans. The sawed cell kept the bulb lit. These images stick. They signal a shift already underway. One that reaches EVs on dealer lots, solar farms feeding data centers, and homes storing cheap afternoon power. The numbers improve each quarter. The deployments multiply. Sodium has moved from laboratory curiosity to commercial contender.
