Solving the energy density challenge with single wall carbon nanotubes
Sponsored by OCSiAl Group Li-ion batteries represent the most dynamic and fastest growing battery market, with total sales of $10 billion in 2015 [i]. Historically, the primary challenge for battery manufacturers has been the constant demand for greater energy density, both volumetric and gravimetric. Li-ion’s dramatic rise is in large part due to solving this challenge more… Read more »
Carpenter Technology develops a new soft magnetic alloy with key benefits for EV motors
Electrical steels are soft magnetic materials found at the heart of electric motors. They’re typically manufactured in cold-rolled strips, cut into shapes to make laminations and then stacked together to form the stator and rotor of a motor. These specialty steels are tailored to produce certain magnetic properties, and have a magnetic flux density (key… Read more »

Seaworthy EVs: Leclanché designs and manufactures Li-ion cells and systems
The advantages of electrifying transportation are far-reaching. Advanced energy storage systems are even making their way into the commercial marine industry. There are many marine applications in which adding a large Li-ion battery pack makes a lot of sense. The best-use case varies depending on the boat size and purpose. All-electric ferries, for example, are… Read more »
An airbag for battery packs: PyroPhobic says its unique thermoplastics will stop thermal runaway
Engineers have been searching for ways to mitigate the risk of fire with Li-ion batteries since the technology was first commercialized. Chemists are creating new cell formulations that are less prone to problems, electronics experts are designing fail-safe battery management systems, and mechanical engineers are building complex cooling and fire suppression systems. A common rule… Read more »

Elon Musk: Tesla can increase the speed of its production line 20-fold
Tesla’s future depends on being able to ramp up to high-volume production quickly. The main pillar of its strategy for doing so is making the production process more efficient – “building the machine that makes the machine,” as Elon Musk puts it. The mathematically-minded Musk has even formulated an equation to quantify the challenge: Production… Read more »
