Solid state battery from Terawatt Technology reaches 432 Wh / kg-state

Terawatt Technology announced in mid-August that you have created a solid battery, which reaches 432 Wh / kg (energy density). This created a battery memory, which comes with 75 percent more power density than one of the most advanced electric cars on the market. The speech is by the way from Model 3. This brings it to a power density of 247 Wh / kg, as Jack Rickard could prove in a Clip from January 2019.

And the company believes it with his Tera 3.0 batteries can reach up to 450 Wh / kg. Nevertheless, there is a hook. So the battery, the Tera 3.0 is called, only 2021 for so-called Early Adopters and 2022 for the wide mass available. Three years of waiting for the company’s first product can be quite long. Especially since the competition does not sleep and increase its power density.

The aim of Terawatt is to produce a semiconductor battery, which reaches 450 Wh / kg and 1.3 kWh / l (energy density). Probably until the time these batteries are offered for sale. A little disillusionment also occurs because the Tera 3.0 should be used more in consumer electronics and not in electric cars. For this you work in parallel at the Tera 4.0 battery, this promises 500 Wh / kg or 1.45 kW / l to deliver. However, a production product is currently not available.

Recently, IMEC has made a solid state battery with an energy density of 400 Wh / liter at a charging speed of 2 hours, a record combination. Now it is correspondingly fast the TERA 4.0 Battery to bring to the market to grasp feet and leave appropriate competition products behind. We will continue to observe which advances Terawatt Technology announces.

  1. Dear editorial,

    Please do not confuse the terms power density and energy density. Accordingly, Model 3 has an energy density of 247 Wh / kg and not power density.

    Best regards
