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!

  • Lighter, cheaper and probably faster!

  • Only a manual transmission would get me in one.... and we know that will never happen

    • You realize there is no transmission in a Tesla?

    • Yes that is the exact reason I said it will never happen.... so but that logic i will never get one.... do you see where this is going??

  • I'm sorry but if you think that just moving something in-house will result in cheaper, better or some other superlative, I can't take the rest of the article seriously. Think about the recent chips fiasco of samsung, the brilliant transmissions zf creates, components of your computer etc. I thought free trade improving efficiency was a econ 100 topic universally but I guess it is not.

    • Well, I’d say my article stands true, based on what battery day stated. Keep in mind this article comes from official sources direct with the matter. Not rumors.

  • I hope Tesla goes out of business in 24 hours

  • So 4 weeks later, their are 10K people still without power in South Louisiana but gas stations have power. I would not buy a car that makes me dependent onnthe power grid
