Tesla has submitted a new patent for improved battery cell chemistry under the title “Dioxazolones and nitrile sulfites as electrolyte additives for lithium-ion batteries”. This is intended to increase the performance and service life of the batteries as well as reducing costs.
Weiterlesen Jeff Dahn and his team, who carry out battery research for Tesla, have published test results for a new battery cell that could have a life of 1 million miles (1.6 million km) and thus be suitable for Tesla’s planned robo taxis. At the same time, Tesla battery cell manufacturing appears to be well underway.

“We’re open to anything that makes sense.”
Jeff Dahn, a leading battery researcher and teacher at Dalhousie University, has taken an exclusive contract with Tesla and was asked to do whatever it takes to improve battery performance. With many wondering if Tesla can realistically reach their targets, Dahn’s contract may signal that Musk is open to other methodologies.

“It helps. It helps the whole industry. Every story about the Model 3 includes a mention of the Bolt EV and our target date is ahead of theirs. We’re on track.”
Shad Balch, New Product and Public Policy Communications at General Motors, talks about the upcoming Chevy Bolt, undaunted by the Tesla Model 3. While the Model 3 has been getting ample press, Balch says it has channelled more interest in the Bolt, which will be on the roads before the Model 3.

“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.
