Factory tour of Shenzhen Grepow battery Co.,Ltd

The video is missing the part where the bad cells are sold cheaply on ebay to people in the US. Then they lie about a warranty and the cost of shipping the bad battery to china costs more than the battery isself.

It's a win win for them.
 
What they showed in the video there is WAY WAY better than your typical RC lipo factory.
 
those last 2 have nice looking equipment but a whole lot of human errors and messy steps involved........ compared for the first one.

Re my comment about working there, it's the production line creation/setup part that i'd love.. something about assembly lines just ... well.. i'm weird.

I'm with you Ypedal, I've spent months in battery factories over the last handful of years, and I still get excited to visit them. :)
 
I guess HK lipo is like pate - you can enjoy the product as long as you don't see how it was made.

Where do we buy Grepow batteries?
 
at the end of the video, imagine if one cell went poof, that would be such a huge fire with the thousands of lipos in cardboard boxes.
 
Oddly, on the how it's made video for "lithium ion batteries", they are not making lithium ion batteries at all, they are making very old school metallic lithium anode batteries that my hunch is for a military or satellite application or something.

Making lithium ion batteries at no point involves handing metallic lithium in any form.
 
Tesla considers massive battery factory

Last night on the conference call, Musk talked about their ideas for the new battery factory, which he said would be “comparable to all of the lithium-ion battery production in the world—in one factory.” If Tesla Motors Inc (NASDAQ:TSLA) moves forward with plans, it would probably be located somewhere in North America.

According to Musk, the facility would likely take in the raw materials and complete the entire process of creating the cells and then assembling the battery packs. Currently Tesla gets its battery cells from suppliers and has them assembled somewhere else. He also said the factory would be eco-friendly in various ways, like using solar power and recycling old battery packs to make new ones. In addition, the facility would create batteries which are similar if not the same as the battery packs they use now.

Tesla challenged by battery supply

So far battery supply has been one of the biggest challenges facing Tesla. Tesla Motors Inc (NASDAQ:TSLA) recently announced that it was expanding its battery agreement with Panasonic so that it will buy three times as many battery cells than it did before. Now the automaker plans to buy at least 1.8 billion battery cells from the company over the next four years, but that still may not be enough.



Musk has said repeatedly that they’ve been having problems getting enough battery cells to keep up with the demand for their vehicles. He also said this has resulted in them not marketing their vehicle as aggressively as they would if battery supply wasn’t a problem.

Some North American customers have had to wait longer for their vehicles so that the company could make deliveries to customers in Europe who had been waiting for their vehicles for years. Tesla Motors Inc (NASDAQ:TSLA) opened its showroom in Beijing recently without much marketing because the automaker didn't want to create more demand than it would be able to meet.

Hi Liveforphysics

They were electroplating /metalizing film and on the second videos slurry coating poly film from what I saw in the videos. One side had some sort of thin lithium compound. Much like a poly capacitor.

You're right, I somehow had this video playing in that window, and thought it was what he had posted. lol

This is a video of a failed battery technology, lithium metal polymer pouch cells.

Most interesting is the first vid with the automated electro dep line. Looks amazing. It does not look like any metalazation lines I have seen. They call it electro chemical in the vid. Wonder if it is some sort of electrostatic powder dep./ coat process. Any idea how thick of a layer they are depositing or what exactly is going on there. Looks to be multy layers of possibly several different compounds.
