“It’s a race among the battery makers to get more and more silicon in. The number of researchers around the world working on silicon for lithium-ion cells is mindboggling. A large number of academics and industrial folks are working really hard on this problem.”
Jeff Dahn, leading lithium-ion battery researcher and professor at Dalhousie University, recently signed a 5-year exclusive partnership with Tesla, who is now using silicon in its 90 kWh batteries to increase capacity, but not the size.
“Even for Tesla, which is very powerful but also fast, one gear is enough.”
ZF engineer Gerhard Gumpoltsberger says that two or more gears only make sense for larger machines like trains and heavy trucks.
