Table of Contents
Augustโฃ 17, 2025 -โข Contemporary Amperex Technology Co. Limited โ(CATL), the world’s leading battery manufacturer [[1]], is poisedโ to introduce a groundbreakingโฃ sodium-ion battery, dubbed Naxtra,โค that could significantly lower the cost of electric vehicles and extend battery lifespan. Production is rampingโฃ up,withโ initial deliveries toโฃ six automakers โslated for โ2026.
A Leap in Batteryโ Technology
The Naxtra batteryโฃ represents a strategic shift away from reliance โon lithium, nickel,โฃ manganese, and โฃcobalt – materials often subject to priceโ volatility andโข geopolitical concerns.Rather,it utilizes sodium,an abundant and inexpensive element commonly found in โฃsalt. This innovative approachโข is โprojected to reduce โbattery production costsโ to approximately 10% โขof current lithium-ion โbatteryโ prices.
CATL initially unveiled plans for the sodium-ion battery in April 2025 alongside other โadvancements, โฃbut is now moving swiftly toward large-scale production. this commitment โunderscores the company’s โขconfidence in the technology’s potential to reshape the energy storage โlandscape.
How โฃNaxtra Differs from Existing Batteries
While sodium-ion batteries have been exploredโข for years, previous iterations suffered from lower โenergy โขdensity andโฃ increased weight, limiting their suitability for automotive applications. CATL’s Naxtra battery overcomes these limitations with an electrolyte designed to prevent dendrite formation โฃand degradation, ensuring โstable performance across a wide temperature range.
the โbattery operatesโ effectively between -40ยฐC andโข +70ยฐC, โmaintaining 90% of its โฃdischarge power even at -40ยฐC. This resilience is a notableโฃ advantage over customary lithium-ionโ batteries, which can experienceโ performance drops inโค extremeโค temperatures.
Key Specifications of the Naxtra Battery
| Feature | Specification |
|---|---|
| Energy Density | 175โ Wh/kg (cell level) |
| Estimated Range | 500 km (real-world driving) |
| Cycle Life | 10,000+ cycles |
| Operating Temperature | -40ยฐC to +70ยฐC |
| Projectedโ cost | 10% โof Lithium-ion |
Didโค You Know? โขSodium-ion batteries eliminate โthe risk of thermal runaway, a common safety concern with lithium-ion batteries, as they lack components that support combustion.
Building on LFP โTechnology
CATL’s โdevelopment of the โขNaxtra battery builds uponโฃ its success withโค Lithiumโค Iron Phosphateโ (LFP) batteries, which already offer a cost-effective alternative to traditional lithium-ion chemistries. LFP batteriesโข currently represent โ40-70% of the cost of comparable lithium-ion batteries, providingโ a 30-60%โค cost reduction. [[3]] Theโ Naxtra batteryโค promises to further reduce โฃcosts,potentially making EVs more accessible to aโข widerโ range of โคconsumers.
Northvolt, a European battery manufacturer, previously announced a solid-state sodium-ion battery with โฃaโ comparable energyโ density โคin 2023, but faced challenges โฃin scaling production. โCATL’s โคapproach, utilizing a more conventional โฃelectrolyte, appears to be โฃacceleratingโค the path โขto commercialization.
Pro Tip: The extended cycle lifeโ ofโข the Naxtra batteryโฃ – exceeding 10,000 cycles – translates to a potential lifespan โof 5 million kilometers, offering exceptional long-term value.
Impact on the โEV Market
The introduction of the Naxtra battery is โขexpected to intensify competition โwithin the electric vehicle market. With a projected cost reduction of up โto 80-90% compared to lithium-ion batteries, automakers utilizing Naxtra technology could offer EVs atโ significantly lower price points – potentially reducing costs by 7,000 to 10,000โค euros per vehicle.
Thisโค cost advantageโข could forceโ other battery manufacturers and automakers to adopt similar technologies or risk losing market share. Will this shift โคlead to a more โaffordable and enduring future for electric mobility? What innovations โขwill โคemerge as โcompetitors respond to โขCATL’s โฃbreakthrough?
The development of sodium-ion batteriesโข represents a crucial stepโ towards diversifying battery chemistries and reducing reliance on criticalโ materials. This trend aligns โwith broader sustainability goals and efforts to build a moreโ resilient supply โchain for โthe EVโฃ industry.Ongoing research focuses โฃon โคfurther improving energy density and cycle life of sodium-ion batteries, paving โฃthe way for even moreโ advanced energy storage solutions โin the future.

Power outages at two AEON stores in Okinawa, lightning strikes on distribution facilities. Rycom’s currently showing movies are suspended; Chatan store will close as is – Ryukyu Shimpo Digital
lightning Strike Causes Power Outages at Okinawa Malls
A powerful lightning strike on September 26th around 3:30 PM caused a critically important power outage affecting AEON Mall Okinawa Rycom and AEON Chatan stores. The incident occurred during a period of heavy rain and thunderstorms. Okinawa Electric Power Company confirmed that lightning struck a power distribution facility, leading to the disruption.
The Rycom store had power restored around 4:15 PM, while the Chatan store was forced to close approximately 30 minutes after the outage began. shoppers at both locations were safely guided outside by staff during the event.
According to Oki Electric Railway, the power failure impacted both the Rycom (Kitanakagusuku Village) and chatan (mihama) locations at 3:39 PM. Power was eventually restored to mihama at 4:46 AM the following day,and to Rycom at 6:10 AM.
An Aeon Ryukyu spokesperson stated that the Rycom store managed to continue operations with manual registers while monitoring the situation. One shopper at Rycom described being evacuated and then encountering traffic congestion when trying to leave the parking lot due to an accident. She was able to return to shopping once power was restored.
An employee from a tenant store at Rycom noted that only customers were evacuated, with staff remaining inside. They reported that customers remained calm and followed announcements. The power outage also led to the suspension of movie screenings at Rycom cinemas and a temporary halt to event activities.While the concession stand was closed, some screenings resumed later in the evening for those with advance tickets.
A visitor to the Chatan store reported that some lights remained on initially, but the air conditioning ceased functioning about 30 minutes after the outage. Store employees informed customers that the mall would be closing due to the inability to operate cash registers and other essential equipment.
PIEZO2 ion channel plays critical role in the formation of coronary vessels and the heart
Ion Channel Discovery Unveils Key to Coronary Vessel Formation
Scientists have discovered a vital role for a specific ion channel in the intricate process of coronary vessel development, opening new avenues for understanding and potentially treating congenital heart defects. This breakthrough could pave the way for earlier diagnostics and intervention.
The Role of PIEZO2
Research, helmed by Dr. Annette Hammes from the Max Delbrรผck Center, has revealed the PIEZO2 ion channel is crucial for developing coronary vessels. This channel, known for detecting touch stimuli, significantly impacts how these vital blood vessels form and function.
Without the PIEZO2 channel, mouse models displayed malformed coronary arteries. These vessels were either too narrow or branched abnormally, which reduced oxygen supply to the heart muscle. This phenomenon mirrors issues seen in humans with Marden-Walker syndrome, a rare genetic disorder caused by an overactive PIEZO2 variant. In both cases, the heart muscle, especially the left ventricle, becomes abnormally thick due to the irregular development of blood vessels.
โMalfunctions in this ion channel during embryonic development may initially lead to subtle yet unnoticeable vascular changes โ only to trigger serious heart issues later in life or under physical stress.โ
โDr. Annette Hammes, Max Delbrรผck Center
According to the American Heart Association, congenital heart defects affect nearly 1% of births annually in the United States, underscoring the need for improved understanding and treatment (American Heart Association).
Further Investigation
Dr. Hammes’ team is collaborating with institutions like the Helmholtz Institute for Translational AngioCardioScience to determine how PIEZO2 can be influenced in humans. They are using human endothelial cells derived from pluripotent stem cells for this research.
The study’s findings could enhance the diagnosis and prevention of genetically caused cardiovascular diseases. Dr. Hammes believes this research expands the list of genes potentially useful in diagnostics and prevention, aiming for earlier detection and intervention.
