HOW IT'S MADE: Tesla 4680 Battery
Tesla would never risk holding back at Battery Day, especially to introduce a new 4680 cell form factor. The novel form factor does away with the tabs, alleviates energy density, supports similar thermal characteristics of smaller cells, betters the power-to-weight ratio, streamlines manufacturing, and is cost-efficient.
Let’s run through each of the advancements that these batteries bring to the table.
This video is going to be all about Tesla’s massive invention with 4680 batteries along with some other related discussions that are currently happening in the said field.

Scale Is Necessary
Tesla was rather satisfied in buying cells with its proper chemistry from its suppliers but came across problems on the horizon. Tesla likes to challenge itself by aiming to develop persistently at a rate of 40–50% every year and to ensure this, they better acquire more and more batteries without compromising on their quality.
Tesla’s battery prediction revealed a lacuna between the production limits of its suppliers and its own internal growing demand for both its automotive as well as energy storage businesses.
As a solution to these issues, Tesla’s teams have been working relentlessly in acquiring as well as designing new technical solutions to facilitate more advancements in the battery cell format.
Besides, Tesla influenced its working in the battery cell manufacturing space in addition to its internationally top-rated manufacturing equipment competency to reimagine the entire process from beginning to finish.
Step Change Advancement In Manufacturing Process
As it desired greater competencies in automotive manufacturing, Tesla quickly raised the bar from simply designing and building products to investing time and mind into the designing aspect of the machine.
With much to do with Musk’s obsession with initial thinking of principles and rationale, he began with every design, every dialogue, and discussion around the bare truth, securing the products to the minerals they are composed of.
In the battery space, we witnessed this company foregrounding new foundations of truths with the possession of the battery as well as supercapacitor pioneers such as Maxwell Technologies and Hibar Systems.
Tesla learned to develop its name through the construction of its first Gigafactory in Sparks, Nevada, obtaining the expertise of manufacturing equipment at the famous Grohmann Automation.
They quickly rose to become the primary developer along the battery cell production lines working under Tesla’s Gigafactory 1, which successfully ensured highly improved production lines by contributing their expertise to the factory since there was a demo and for more cell production capacity.
Bettering each of the primary silos that comprised a battery was cooperative and led to great results at Gigafactory 1, but Tesla had in its store a much wider vision. It was full integration. Tesla’s persistent pursuit of vertical integration buds from a longing to completely annihilate and better the sustainability of the said product.
A byproduct of such vertical integration is a much-needed factor of cost-efficiency during manufacturing that is helping to drive the cost of Tesla’s products low over time. The architecture of the novel 4680 cells also bears a direct influence in bettering manufacturability. In addition to the tabless design that eliminates the requirement for a tab, it also thrashes any need for the production lines to waste time to add the tabs.
These cells do away with this bump in the road that has helped to facilitate a manufacturing line that is somewhat less vulnerable to manufacturing defects which led to the rolling up and spitting out these great 4680 cells.
If we really think this through, a conclusion can be very easily drawn here that it is not just a concept or an exhibition of any sort. They have clearly stated how they are beginning to amp up the manufacturing of these products at their pilot 10 GWh production facility.
Often referred to as Project Roadrunner, Tesla founded a pilot line specifically to serve for the manufacturing processes of these cells, and the CEO of Tesla, Elon Musk, announced how they look forward to amping the pilot line processes up, in terms of gigawatt-hour and, whenever required, to even terawatt-hour scale.
Musk said that even though it might take some time to reach the 10 GWh mark of production capacity, they expect to give it the sweet start in the new production lines not more than the next 12 months from now. Once the said goal is achieved, they are ready to drive scale.
