German deep-tech startup Pulsetrain said it is working with automotive supplier Yazaki to bring a new battery architecture based on so-called multilevel technology closer to series production, as automakers seek more efficient and compact electric vehicle systems. The two companies are jointly developing an intelligent “MultiCellBridge,” which integrates functions such as cell management, inverters and charging units directly into the battery system. Pulsetrain said the partners aim to demonstrate industrial feasibility through a proof of concept. “As part of a proof of concept, the partners aim to demonstrate the industrial feasibility of this key technology—to significantly enhance the efficiency, safety,…

CATL expects to begin deploying sodium-ion batteries in passenger vehicles as early as the second quarter, marking a significant step toward large-scale commercial adoption of the technology, the company’s chief technology officer said. “The first passenger vehicle equipped with sodium-ion batteries will come from GAC Aion,” CATL CTO Gao Huan told China Securities Journal in an interview published on Thursday. “As production capacity expands, sodium-ion batteries will gradually scale up for passenger vehicles, commercial vehicles, energy storage, and even construction machinery.” See also: China Regulator Probes Ronbay After CATL Supply Deal Announcement CATL, formally known as Contemporary Amperex Technology Co…

CATL has launched a sodium-ion battery designed for light commercial vehicles, marking its first major step this year toward large-scale adoption of the alternative battery chemistry, as the world’s largest battery maker looks to reduce costs and improve performance in extreme climates. The company unveiled its new Tectrans II series of power batteries on Thursday, positioning the range primarily for light commercial vehicle applications such as small vans and micro trucks. A low-temperature variant within the series uses sodium-ion technology, which CATL said is the industry’s first mass-produced sodium-ion battery specifically developed for light commercial vehicles. The sodium-ion battery pack…

Octillion Power Systems said it produced a record 3,653 electric vehicle battery systems in a single day on Dec. 3, 2025, representing around 114 megawatt-hours of energy capacity across its global manufacturing network. The output was achieved across nine production facilities located in the United States, India and China, underscoring the company’s strategy of localized manufacturing aligned with original equipment manufacturer demand. The battery systems support a range of vehicle applications, including passenger cars, trucks, buses and commercial vehicles. “For Octillion to surpass 3,650 battery systems produced in a single day is a momentous achievement,” said Paul Beach, global president…

A circular economy approach to electric vehicle batteries could help avert looming shortages of critical minerals and curb sharp price increases for consumers, according to a new report published by the Ellen MacArthur Foundation. The report, titled “Leading the Charge – Turning risk into reward with a circular economy for EV batteries and critical minerals,” was launched at the World Economic Forum in Davos and outlines five priorities aimed at reshaping how batteries are designed, used and recovered across their lifecycle. The Foundation warned that supply shortfalls in key battery materials are likely to emerge by the mid-2030s, potentially driving…

Connected Energy, a British specialist in stationary energy storage systems using second-life electric vehicle batteries, plans to invest £2 million in a new testing centre for used EV batteries in eastern England, the company said. The facility will be built at Scottow Enterprise Park in Norfolk, close to Connected Energy’s existing technical centre, and is expected to become operational by mid-2026. The project is supported by the Advanced Propulsion Centre UK as part of a broader initiative to strengthen reuse and recycling pathways for electric vehicle batteries. Connected Energy focuses on repurposing retired EV batteries for grid-connected battery energy storage…

Ministry of Industry and Information Technology (MIIT) said China will require electric vehicles to retain their power batteries when they are scrapped, as authorities move to tighten oversight of battery recycling amid a surge in retired batteries from the fast-growing EV sector. The requirement was outlined in a policy document released on Friday by six government departments, including MIIT, and will take effect on April 1, 2026. The rules are intended to prevent discarded power batteries from entering informal or unregulated recycling channels.

Belgian research and materials company Syensqo and French energy firm Axens have formed a joint venture, Argylium, to develop and scale materials for solid-state batteries, aiming to bolster Europe’s battery value chain for next-generation energy storage. Argylium will focus on sulphide-based materials designed exclusively for all-solid-state batteries, which eliminate liquid electrolytes in favour of solid, ion-conducting components. Solid-state batteries are widely seen as a key future technology due to their potential for higher energy density, faster charging, longer driving range and improved safety compared with conventional lithium-ion batteries.

Hongqi, the premium automotive brand of China FAW Group, has introduced its first prototype vehicle equipped with an all-solid-state battery, marking a milestone in its efforts to advance next-generation battery technology toward mass production, the company said on Thursday. The all-solid-state battery pack, developed by Hongqi’s research and development headquarters, was installed on Dec. 31 in a Hongqi Tiangong 06 prototype vehicle, enabling the brand to begin real-vehicle testing of the technology. The company did not disclose details on the battery’s energy density or the vehicle’s driving range. See also: Baidu Robotaxi Falls Into Construction Pit in Chongqing, Passenger Unhu…

China has launched a public consultation process for its first national standard governing solid-state batteries for electric vehicles, a move seen as a key step toward the commercialization of next-generation battery technology, according to a notice released by the country’s auto standards authority. The draft standard, titled Solid-State Battery for Electric Vehicle – Part 1: Terms and Classification, was issued by the National Technical Committee of Auto Standardization on December 30. The consultation period will run until February 28, 2026. The document establishes foundational definitions and technical classifications for solid-state batteries, laying the groundwork for future regulatory and industrial alignment.…
