Here's everything Tesla will announce on Battery Day before you're supposed to know
Here's everything you need to know about Tesla Battery Day, before you're supposed to know about.
Due to the powerful tool of the internet and knowing the right people, we now know a big part of what Tesla is going to announce for Battery Day.
Tesla will manufacture its own cells after acquiring Maxwell Technologies, a company that specializes in supercapacitor production. Tesla also bought Hibar Systems, an equipment manufacturer. By buying these two companies, it will allow Tesla to improve energy density and reduce costs. And while that may all sound Chinese, bear with me, as it all translates to some great news.
One of the big issues Tesla is facing is the cost of its cells, or more specifically, cathode manufacturing. The cathode bit of the cell itself accounts for 50% of the price for the whole cell. Beforehand, Tesla relied on other manufacturers to supply cathodes for them. But now that Tesla has bought Maxwell Technologies and Hibar Systems, these cells will be built in house, the cells will become better and cheaper.
So here's the direct result of all of this: Energy density will go from 250Wh/kg per cell to 400Wh/kg per cell. This means batteries will now be lighter, making the weight a Tesla car lighter, and the performance better.
The other bonus to building cells in-house is that it will ultimately bring costs down, by A LOT. Tesla is expected to announce that the average battery pack will cost Tesla at or below $100/kWh, while before it was $128/kWh. By 2025, Tesla believes that pack prices will go down to $80/kWh. And here's why this is a big deal: if Tesla batteries become cheaper to make, that means that their cars and trucks are going to become cheaper and more affordable.
Wrap it up
In simple terms, Tesla's are going to become lighter and cheaper, a win-win for everybody. All of this will be officially announced officially on 9/22/20 at 4:30 pm EST. And now, you know ahead of time!
