US-based battery company Nuvola Technology has demonstrated that its SafeCoat Direct Deposition Separator (DDS) can prevent thermal runaway in lithium-ion batteries under extreme conditions that typically result in catastrophic fires. In testing, Nuvola’s 41-layer, 5 Ah lithium-ion pouch cell with SafeCoat DDS survived nail penetration testing, maintaining its charge without ignition or thermal runaway. That… Read more »

Altech demonstrates safety of sodium-nickel-chloride batteries under destructive test conditions
Solid-state battery developer Altech Batteries has completed a full suite of safety self-destruction validation tests on its sodium-nickel-chloride (SNC) battery technology, which it recently began selling. The tests were designed to simulate the most severe field hazards that can occur during storage, transport or operation. Across all the scenarios, which included direct fire exposure, rod… Read more »
Dürr unveils X.Cellify DC dry electrode coating system for battery manufacturing
Dürr has announced the development of X.Cellify DC, a dry electrode coating process that forms a free-standing film of active battery material, which is fully recyclable until it is laminated onto the collector foil. The company says this approach reduces active material waste in battery electrode production, and its proof-of-concept confirms the technology’s reliability, scalability,and… Read more »
Edge Energy’s single-phase DC fast EV charging platform can cut installation time and cost
Edge Energy has collaborated with Lincoln Electric to develop a new charging platform designed to bring EV charging to locations that lack access to three-phase power. The single-phase 100 kW charging platform is built on Edge Energy’s solid-state digital phase conversion technology, and integrates Lincoln Electric’s Velion 50 kW DC fast chargers with DC America’s… Read more »
A closer look at capacitor precharge and inrush current control
The vast majority of power converters used in the EV space—from battery chargers to traction inverters—are classified as voltage-fed, meaning they expect to be supplied from a source whose voltage varies little with changes in current draw (i.e. has a low impedance), and the best way to ensure this condition is with a capacitor across… Read more »
Inside the EV battery recall process—the complexity of safety and logistics
As EV adoption accelerates, so does the frequency of battery recalls—and the operational expertise they require. In recent months, a string of recalls from major automakers has underscored the complexities of EV battery systems. Hyundai recently pulled back a limited number of 2025 IONIQ 5s in the US after identifying a short-circuit risk linked to… Read more »
Sakuu reports breakthrough in dry-processed battery cell, retaining 83% charge after 4000 cycles
Sakuu has announced that its Kavian additive manufacturing platform can dry-print lithium-ion battery cathodes with leading cycle life using existing high-nickel chemistry. The company claims that cells manufactured via Kavian’s fully dry process retained 83 percent of their original charge capacity after 4,000 cycles, surpassing typical standards for EV batteries. According to Sakuu, the tested… Read more »
Optimizing the thermal management Ecosystem in EV batteries
Sponsored by Avery Dennison. Continued optimization of battery design means addressing thermal runaway and other issues. Pressure-sensitive adhesive (PSA) tapes may be an important part of the solution. By Max VanRaaphorst, Market Manager, Energy Storage, Avery Dennison This is a dynamic time for the electric vehicle marketplace. According to an April 2025 report by Cox… Read more »
Altech to start selling sodium nickel chloride (SNC) batteries
Australian solid-state battery developer Altech Batteries has entered the market for sodium nickel chloride (SNC) batteries—previously referred to as sodium alumina solid state (SAS)—in Australia, Europe and the US through a strategic collaboration and distribution agreement with AMPower. AMPower is a subsidiary of Chilwee Group, a Chinese battery manufacturer, which has production capabilities spanning lead-acid,… Read more »
Nuvvon battery with solid polymer electrolyte passes nail penetration tests
US solid-state battery technology developer Nuvvon’s polymer electrolyte has passed a series of nail penetration tests, which create a short circuit inside the cell to determine if the battery catches fire or explodes. In two sets of tests, which were conducted at The University of Texas at Austin (UTA), traditional 1 Ah cells of commercial… Read more »
