Some changes in Lithium form?

The battery event will follow the company’s annual shareholder meeting Tuesday afternoon at Tesla's U.S. assembly plant in Fremont, California, south of San Francisco. Musk has made made vague references about emerging battery technology on Twitter, and analysts expect him to announce a battery that will be able to travel 1 million miles before its storage capacity begins to deteriorate.The new technology may rely on lithium metal, a replacement for the current lithium ion batteries now used in Tesla and other electric vehicles. Lithium metal can store more energy than lithium ion batteries and can handle more charging cycles, but it’s difficult to manufacture and keep the temperature stable, said Guidehouse Principal Analyst Sam Abuelsamid.“Everybody's been been trying to make lithium metal viable,” Abuelsamid said. “If they can do it, that would definitely make for an advance in energy density.”Tesla also could announce another chemistry, lithium ion phosphate, which is used in China. It can be recharged many more times than lithium ion, and is stable and safe to use, but it doesn't store as much energy, Abuelsamid said.The new chemistry likely will be needed as Tesla rolls out larger vehicles including its “Cybertruck” pickup and a Semi that is under development. The pickup will be available late next year, while Semi production is to begin sometime during 2021.“We know TSLA is going to promote its technology and needs to if Semi and Cybertruck are the next platforms both requiring high density solutions,” Canaccord analyst Jed Dorsheimer wrote.“The big question will be on follow through. It’s one thing to announce all these breakthroughs, which might be great for momentum algorithms, but like most things (Tesla), the devil will be in the details, which sadly will take some time to play out,” Dorsheimer wrote.
