Tesla unveiled plans Tuesday to develop a “tabless” battery that could improve an electric car’s range and power. The company will produce its new batteries in-house, which Tesla CEO Elon Musk predicts will help dramatically reduce costs and allow the company to eventually sell electric vehicles for the same price as gasoline-powered ones.

The battery is expected to lower Tesla’s cost per kilowatt-hour, the unit of energy most commonly used to measure the capacity of the battery packs in modern electric vehicles.
...
Musk said Tesla achieved this breakthrough by removing the tab, a part of the battery that forms a connection between the cell and what it is powering. These new tabless cells, which Tesla is calling 4860 cells, will give the company’s EV batteries five times more energy capacity, make them six times more powerful, and enable a 16 percent range increase for Tesla’s vehicles.

Solid state batteries are a larger improvement. They provide approximately double the power density.

Solid state batteries are a larger improvement. They provide approximately double the power density.

Perhaps. It's exciting that so much is happening in this field. But it should be mentioned that Tesla was getting 250 Wh/KG in 2018, and currently the solid state technology is only at 150 Wh/KG. Solid state manufacturers state that 400 Wh/KG is on the horizon. Tesla states that 400Wh/KG is 3 years out. Based on the gap to close, I would put my money on Tesla.
