LeydenJar says its silicon anode boosts battery energy density by 70%

LeydenJar Technologies, a Dutch spinoff of the applied research institute TNO, has developed a new battery anode that’s made from 100% silicon. The company says this provides two key benefits: batteries with a 70% higher energy density (1,350 Wh/L) and 62% lower CO2 emissions than current models. The anode is ready for production, and LeydenJar… Read more »

Webinar tomorrow: Rework ability of gap fillers in EV battery packs

The fast-growing electric vehicle market demands robust and efficient thermal management solutions for battery packs, such as gap fillers and thermal pads. Gap fillers outperform thermal pads to achieve lower thermal impedance, as the gap fillers conform to surface roughness before curing. This allows gap fillers to adhere well to surfaces and provide mechanical support… Read more »

UN highlights social and environmental impacts of surging demand for battery raw materials

Demand for raw materials used in the production of EV batteries is expected to soar, and the UN trade body, UNCTAD, says the industry urgently needs to address the social and environmental impacts of the extraction of raw materials. UNCTAD predicts that the market for EV batteries will grow from an estimated $7 billion to… Read more »

Elon Musk offers to let automakers license Tesla’s tech (again)

Tesla’s mission has always been to advance the transition to electromobility, and Elon Musk has said many times that he’s open to licensing deals that would allow other automakers to use the company’s technology. As far as we know, only two major brands have ever taken Tesla up on the offer: back in the 2010s,… Read more »

Linear Labs to mass-produce new hub motor in Texas for light EV and marine applications

Electric motor maker Linear Labs has announced that starting this September, it will be mass-producing its high-torque M200 e-mobility motor for off-the-shelf use. The announcement comes on the heels of a $68.9-million economic incentive deal with the city of Fort Worth to bring advanced automation manufacturing to the Texas metropolis. The company will start with… Read more »

DOE issues RFI to strengthen critical battery material supply chains

The DOE has issued a request for information (RFI) on challenges and opportunities in the upstream and midstream critical battery material supply chains. “As the demand for critical materials continues to grow, a secure and domestic upstream supply chain becomes vital,” said Assistant Secretary for Energy Efficiency and Renewable Energy Daniel R. Simmons. “Innovation in… Read more »

Sunstone Engineering’s new battery welding system enables copper and nickel tab welding

Sunstone Engineering, a manufacturer of high-tech micro-welding and engraving solutions, has developed a new battery welding system that’s capable of welding copper and nickel tabs to power cells. Sunstone’s Omega PA250i includes new welding technology that clears a path for battery manufacturers to use pure copper or nickel tabs in the production of power cells…. Read more »

Renesas unveils integrated LIN interface sensor signal conditioner for EV HVAC Systems

Renesas Electronics recently introduced the ZSSC4132—an automotive pressure sensor solution featuring an integrated certified LIN v2.2a interface. Available in a single-package compact form factor, the sensor signal conditioner (SSC) is designed for EV climate control systems. Renesas says the AEC-Q100 qualified ZSSC4132 can be configured for nearly all resistive bridge sensors.  “HVAC plays a significant… Read more »

Freudenberg develops thermally conductive elastomer for EVs

Engineers at Freudenberg Sealing Technologies have developed an elastomer that merges relatively high heat capacity with electrically insulating properties by combining silicone rubber with special fillers. Electronic components can be mounted in a thermally conductive aluminum housing, which dissipates heat through cooling water or convection. Senior Application Manager Armin Striefler explains why Freudenberg decided to… Read more »
