RE: Tesla question ?13 Jan 2020 17:52
Hi Robin
The Tesla question is extremely interesting and very pertinent, I have been following Tesla for some time and I am desperately awaiting their Investors Battery and Power-train day which was set for late last year and is now slated for sometime in Q1 this year. My take is that they will reveal quite a lot. From Elon Musks presentations for his new Roadster, Semi and Cybertruck it is obvious that there must be a new / different battery about to be unveiled: these vehicles are being offered with 500 miles of real world range at very competitive prices.
Around 2016 Professors John Goodenough (co-inventor of the Lithium-ion battery) and Helena Bragga put out a paper on a glass electrolyte battery effectively the much vaunted solid state battery, it was met with a lot of skepticism, interestingly there has not been any rebuttable from the scientific community so I presume it was true. It is very likely they contacted Tesla about this (they do use half of the worlds supply of Lithium-ion batteries ) and they do have a battery guru Jeff Dahn at Dalhousie University on the payroll to check it out. Apparently it takes three to five years minimum to develop and bring into production a new battery so given that Tesla is very interested and committed to bringing down battery prices they probably put it on the very fast track.
Last year Tesla bought Maxwell Technologies (makers of Ultra Capacitors and developers of a dry battery electrolyte for Lithium-ion batteries) and Hibar Systems (manufacturers of machinery and equipment for producing Lithium-ion batteries and other precision tooling).
Speculation here I think Tesla will be announcing that they have a new lighter, more energy dense, longer lasting and more durable battery that is cheaper to produce and very quick to charge probably with either a dry battery electrolyte or a solid glass electrolyte and that they intend to manufacture the new batteries themselves in enormous quantities
