Tesla disclosed its plans on Tuesday to produce a “tabless” battery, that’ll expand the amount of e-cars and boost their power. Tesla’s CEO Elon Musk noted that the company is ready to open up its in-house battery production. This step, in optimistic days, is supposed to cut the price of e-cars so they’ll cost the same as gasoline-powered cars. 

Andrew J. Hawkins wrote for The Verge that the battery should diminish Tesla’s cost per kilowatt-hour – the measure that counts the capacity of the battery packs. As a result, pulling this lever will take the reduction of the price for Tesla cars with it. The information about the new battey happened to appear during the company’s “Battery Day” in Palo Alto California. 

For a better understanding of what exactly happened, Elon Musk said that Tesla could afford these changes because they’ve removed the tab, a part of the battery that forms a connection between the cell and the power part. These tabless cells Tesla calls – 4860 cells, and they are like legendary objects with orange frames, because they will boost EV batteries a lot. They will increase the energy capacity by five times, make them six times more powerful, and will raise up Tesla’s vehicle’s range by 16 percent.

However, the rule of equivalent exchange says “You should pay the equivalent price”. Tesla has sacrificed the size of the batteries, making them bigger (46 millimeters by 80 millimeters – 4680). Also, Tesla lovers should totally appreciate a 14 percent reduction in cost per kWh at the cell from factor level only.

From Drew Baglino, Tesla’s vice president for powertrain, comes the explanation of the technical part of the new cells, but in easy words. He said that Tesla’s engineers “laser patterned” the existing foils in the cell to create a “shingled spiral” that’ll cut the electrical path length of 50mm from the current 250mm length in old cells. 

“You actually have a shorter path length [for the electron to travel] in a large tabless cell than you have in the smaller cell with tabs,” Musk added. “So even though the cell is bigger, it actually has more power.”

Tesla is big enough to finish the quest with external battery producers so the company can build more cars. Panasonic has produced 2710 cells for the Tesla Model 3 and Model Y at Tesla’s Gigafactory in Nevada.

Tesla isn’t going to dump those batteries all of a sudden. Musk posted a tweet that the company will keep on using batteries supplied by Panasonic, China’s CATL, South Korea’s LG Chem, and others.
