In an article posted by EV Specifications, it reports that South Korean publication The Elec says that industry sources from South Korea show that Tesla will produce its own batteries. They get their information from the fact that Daebo Magnetic will likely be the supplier of the electromagnetic filters that are needed to produce the batteries. Daebo Magnetic is a battery equipment manufacturer headquartered in South Korea. The sources also say that these products could possibly enter Tesla’s Nevada Gigafactory by the end of this year.
Daebo Magnetic is reportedly the only manufacturer globally that creates wet-type electromagnetic filters that are “used to remove foreign substances before the battery is assembled.” It has developed and produced magnetic separators and other magnet-related devices. Magnetic separation simply means that anything that has magnetically susceptible particles is separated from its non-magnetic particles.
Ever since Tesla acquired Maxwell Technologies, many have been thinking that Tesla does want to start making its own batteries. Its purchase of Hibar Systems earlier this fall just added more weight to this theory. Since Tesla is in the energy business, it makes sense that it would want to create its own batteries at the cell level as well as the pack level.
Last month, several news reports revealed that Tesla could have a battery that lasts a million miles, which is well more than double what drivers can expect right now. At Tesla’s Autonomy Day back in April, Elon Musk promised that Tesla would soon be able to have enough power for its vehicles to last one million miles. He was, of course, ridiculed and mocked by his critics, but a group of researches at Dalhousie University who work with Tesla published a paper in the Journal of Electrochemical Society that describes a lithium-ion battery that “should be able to power an EV for over 1 million miles.”
In June, CNBC reported that Tesla had a “secret lab” where it was developing its own battery cells. Battery cells, for those who may not be aware, are the key components of a battery module. Battery packs are made up of multiple modules, and provide the power for electric vehicles. Usually, EV makers source cells from manufacturers and then create modules or battery packs that are compatible for their vehicles. A great example of this partnership is Tesla and Panasonic. To date, this partnership between Tesla and Panasonic produces around 60% of the world’s electric vehicle battery output.
Amazing results by @Panasonic at Tesla Gigafactory Nevada! Very much appreciate extreme hard work it took to achieve this result. Together with Pana Japan cell plants, Tesla/Pana partnership is producing ~60% of global EV battery output!

If Tesla were to build its own batteries, this would allow Tesla to better optimize them for its own needs, such as longer range, as well as cut down production costs. If Tesla was to make its own battery cells and eventually cut out the “middle men,” then production cost could be significantly lower.
Whether or not the South Korean sources have come to the right conclusion, Tesla seems to be on the path to creating not just its own batteries, but as it has done in various ways with the auto industry, it will probably revolutionize the battery industry as well. This could lead us into a safer and less toxic way of creating batteries while inspiring competitors to jump in and make their own. Either way, this is a technology that we are all looking forward to seeing developed.
I don't like paywalls. You don't like paywalls. Who likes paywalls? Here at CleanTechnica, we implemented a limited paywall for a while, but it always felt wrong — and it was always tough to decide what we should put behind there. In theory, your most exclusive and best content goes behind a paywall. But then fewer people read it! We just don't like paywalls, and so we've decided to ditch ours. Unfortunately, the media business is still a tough, cut-throat business with tiny margins. It's a never-ending Olympic challenge to stay above water or even perhaps — gasp — grow. So ...
