The company I work for producing battery mainly for storage. Now it's your term!
Hello guys I'm new here. I work for a China battery company and I guess I know something you're interesting in. Ask whatever you wanna know

No but they seem to be a Chinese trader

You wanna see the cells production line or packs production line?

I wait for a couple of minutes for the video to upload and only gets this. I'll try with some pictures

Some are 32700 cells. Some are prismatic cells, 3.2V 50Ah

It's hard to upload videos. Hope the admin will update the system soon
You may have to upload to youtube and insert video links here.

Have you ever had an incidents? you know, someone drops a wrench on a battery, something explodes, etc?

Why do you think the battery will explode if you drop a wrench on it?

In battery manufacturing, there are two specified tests. In the first test, after charging the battery cell according to the specifications of 3.2, a heat-resistant steel needle with a diameter between ϕ5 mm and ϕ8 mm is used. The needle is inserted at a speed of (25±5) mm/s, perpendicular to the direction of the battery cell's electrode plate. The penetration point should be close to the geometric center of the pierced surface. The steel needle is left in the battery cell, and observation is carried out for 1 hour.
In the second test, the battery cell, charged according to the specifications of 3.2, is subjected to compression. A semi-cylindrical body with a radius of 75 mm is pressed vertically towards the direction of the battery cell's electrode plate at a speed of (5±1) mm/s. The compression is stopped when the voltage reaches 0 V, or the deformation reaches 30%, or the compression force reaches 200 kN. Observation is conducted for 1 hour after the compression.
The final result must be that the battery cell does not explode or catch fire.
I am more interested with the gray market questions.
I understand the best batteries are reserved for those high end automotive or stationery energy storage stuff.
How about those cells that don't pass the test? There are many questions I like to ask about these "unwanted" cells that currently in gray market.3

- Why are those cells "discarded"?
- What kind of tests that make those cells failed to be qualified?
- Why company doesn't simply recycle those failed cell, yet they auctioned those and many unscrupulous people "relasered" it to trick people?
- Why the manufacture does have DIRECT TO Customers sales?

Are the 32700 cells the largest of that format? What are they typically used for?
