SEO (Reuters) – Tesla Inc (TSLA.O) Chief Executive Officer Elon Musk suggested that the American electric car manufacturer may be able to make longer-lasting batteries with 50% higher energy density in three to four years.

“High cycle life with 400 Wh / kg *, produced in volume (not just a lab) is not far off. Probably 3 to 4 years,” Musk tweeted on Monday ahead of his anticipated “Battery Day” event, where Tesla finds that it has improved its battery performance.

Researchers have said that Panasonic’s energy density6752.T) “2170” The battery used in Tesla’s Model 3 is about 260Wh / kg, which means a 50% jump from the current energy density, which is important to achieve a longer driving range.

Tesla said its Battery Day would take place on the same day as it did at the 22nd annual meeting of shareholders in 2020.

The electric car manufacturer also showed a background image where several dots are clustered into line structures, which leads to speculation among media and fans about what it would reveal on the incident. (here)

South Korean battery expert Park Chul-wan said the image could hint at a “silicon nanowire anode”, a breakthrough technology that could potentially rapidly increase both battery energy density and battery life.

Panasonic Corp (6752.T) Previously told Reuters that it plans to boost the energy density of the original “2170” battery cells that supply it 20% to Tesla over five years.

Tesla is also working with China’s Contemporary Ampex Technology Limited (CATL) (300750.SZ) To introduce a new low-cost, long-life battery in its Model 3 sedan in China later this year or early next year, with batteries designed to last up to a million miles, Reuters Reported in May.

A very “limited number of shareholders” will be able to participate in 22 events due to epidemic-related restrictions, Tesla said, and a lottery will be held to select attendees.
