getting carmakers to use recycled materials remains a hard sell. “In general, people's impression is that recycled material is not as good as virgin material,” says Yan Wang, a professor of mechanical engineering at Worcester Polytechnic Institute. “Battery companies still hesitate to use recycled material in their batteries.”
A new study by Wang and a team including researchers from the US Advanced Battery Consortium (USABC), and battery company A123 Systems, shows that battery and carmakers needn't worry. The results, published in the journal Joule, shows that batteries with recycled cathodes can be as good as, or even better than those using new state-of-the-art materials.
The silicon carbide will specifically be used in the integrated power electronics contained within GM’s Ultium Drive units in its next-generation EVs.
Faraday's original electric motor design used was an axial type, more flux are in the working zone of the motor therefore having higher efficiency compared to the common radial type
Much of the early enthusiasm for the automobile stemmed from its promise to solve the problems associated with horse-drawn vehicles, including noise, traffic congestion and accidents. That cars failed on each of these counts was tolerated because they offered so many other benefits, including eliminating the pollution – most notably, horse manure – that had dogged urban thoroughfares for centuries.
