Tesla CEO Elon Musk has suggested that the automaker may be able to produce batteries with 50% more energy density within three to four years. This news comes ahead of the firm's "Battery Day" event where it is expected to reveal improvement in its battery performance.


400 Wh/kg *with* high cycle life, produced in volume (not just a lab) is not far. Probably 3 to 4 years.
— Elon Musk (@elonmusk) August 24, 2020
According to researchers, the energy density of Panasonic's "2170" batteries that Tesla uses in its Model 3 cars is roughly 260Wh/kg, which would mark a 50% surge from current energy density. Battery Day will take place on September 22, which is when Tesla is also holding its annual shareholders' meeting. Due to coronavirus restrictions, the automaker will have limited attendees who will be selected via a lottery.

The event's background image shows white-colored dots clustered in line formations, which Park Chul-wan, a South Korean-based battery expert, believes to hint at "silicon nanowire anode." This breakthrough technology could help Tesla substantially increase both battery energy density and battery life.

Currently, Tesla's batteries are manufactured in partnership with Panasonic at the Nevada Gigafactory, and the automaker also has battery contracts with LG Chem and Contemporary Amperex Technology. Earlier this year, it was reported that Tesla was planning to build a battery research and manufacturing facility in Fremont.

I hope there is more to tell on sept. 22 though.. people arent really gonna wanna hear.. "We are gonna do this in 4 years"

Like yeah ok.. but what about right now?! Hopefully they are manufacturing these batteries to put into something like the Roadster NOW and they will trickle down through the lineup as production ramps.

Elon promised 9/22 will be a "mind blowing" day. He mentioned that it blows HIS mind so I do think it's something pretty big. V2G charging? 100% silicone nanowire batteries? Leasing battery packs? Mind blowing battery production speed?

Hey medicaljmp, I think I’m two in front of you in line. Maybe he’ll have the batteries perfected by then.

I'm only 54,000ish in line so I am likely going to get the old junky style batteries in mine. =P

Don’t worry, after 6 months they’ll just open it up as a free for all....first order, first served
