Recently, Hitachi ltd. and Tohoku University’s Advanced Institute for Material Research (AIMR) group have developed a basic technology to improve thermal durability in lithium-ion batteries, as reported by CrazyEngineers.com. This basic technology reduces “the internal resistance of all-solid-state lithium-ion [batteries] using a complex hydride as a solid electrolyte,” the … [Read more...]
New Cooler Can Advance Heat Exchanger Technology
Recently, researchers at the Energy Department’s Sandia National Laboratories have developed an innovative new air-cooling technology called the Sandia Cooler. “The Sandia Cooler combines a fan and a finned metal heat sink into a single element called a heat-sink-impeller in which the fins of the heat sink rotate, improving heat transfer by a factor of ten,” reports … [Read more...]
Faulty Batteries and Lack of Cooling System Causes Hoverboards to Explode
Due to cheap, faulty batteries, hoverboards are catching fire and exploding. These self-balancing scooters run on rechargeable lithium-ion batteries, and because consumers are looking for more affordable items, they are buying hoverboards with cheaper batteries installed. Professor of Materials Science & Engineering at Carnegie Mellon University, Jay Whitacre, says, … [Read more...]
New Cooling System for Automotive Battery is Simpler and Offers Higher Cooling Rates
As electric cars go to higher charging rates, better cooling will be needed. Direct Expansion, or DX, is a new cooling system that “uses the same refrigerant as used in your vehicle’s air conditioning system to cool the battery directly,” according to HybridCars.com. DX eliminates liquid glycol, even has a cooling rate of 3-4 times higher, and simplifies the battery’s … [Read more...]
New High-Rise Nano-Materials Incorporate Thermal Cooling Layers
Researchers and Stanford engineers are creating a new approach to the layout of computer processors and memory chips (called Nano-Engineered Computing Systems Technology, or N3XT) where processors and memory are stacked on top of one another like a high-rise architecture. This could cause immediate problems involving heat, but Stanford mechanical engineers Kenneth Goodson and … [Read more...]
