Delphi announces combined inverter and DC/DC converter for Chinese market

Delphi Technologies plans to introduce what it says is the first combined inverter and DC/DC converter in China. The addition of these components is expected to create a more efficient and cost-effective way to deliver increased power density in a smaller and lighter package. The potential to deliver more efficient electric propulsion systems has already… Read more »

New Li-ion battery sensor tech promises 5x faster charging

According to researchers at the University of Warwick (UK), a new testing technique they have developed shows that commercially available lithium-ion batteries can safely be charged up to five times faster than currently recommended. In a paper entitled “Understanding the limits of rapid charging using instrumented commercial 18650 high-energy Li-ion cells,” published in the journal Electrochimica… Read more »

Garnet ceramic electrolyte helps block dendrite formation

Researchers at the University of Maryland have developed a new template that they hope will enable a safer alternative to liquid electrolytes, which have several drawbacks, including flammability, leakage and dendrite formation in the electrodes. In “Lithium-ion conductive ceramic textile: A new architecture for flexible solid-state lithium metal batteries,” published in Materials Today, UMD researchers… Read more »

Tesla to establish electric motor R&D group in Greece

Tesla is expanding its international R&D operations with a small office in Athens, Greece to develop new electric motor technologies. According to Greek Reporter, Tesla Greece has been officially registered, and expects to recruit up to 50 R&D staff over the next few months. Why Greece? For one thing, three of Tesla’s top electric motor… Read more »

Toyota develops new magnet cutting the use of rare earth element neodymium in electric motors

Scientists at Toyota have developed a new heat-resistant magnet that uses “significantly less” neodymium, a rare earth element commonly used in magnets for electric motors. Neodymium is critical for maintaining magnetization at high temperatures. The amount of neodymium in Toyota’s magnets has been reduced by up to 50 percent, partially replaced with lower-priced rare earths… Read more »

Increasing concentration of LiFSI salt suppresses dendrite formation

Lithium metal is considered an ideal anode material due to its exceptional charge and storage capability, but it has a tragic flaw: root-like growths called dendrites, which can lead to short-circuiting and spontaneous combustion. Now, researchers at the University of Maryland (UMD) have announced a breakthrough in their quest to solve the dendrite issue. In… Read more »
