In pursuit of rapid expansion of its own battery cell production, Tesla is accelerating its recruitment for related positions. The company launched a page on its website whereby it is possible to get acquainted with relevant information, as well as to apply for a job at Tesla in specialties that pertain to the production of battery cells.
'Tera is the New Giga'
Tesla explains that in order to move to sustainable energy as quickly as possible, the company must make more affordable cars. This will only be possible when Tesla achieves its goal of producing cheaper battery cells.
At Battery Day, the company unveiled its new 4680 cell architecture, which is significantly larger than the current 2170 cells. New technologies are used to manufacture new batteries, which require a lot of specialists to scale up production.
Tesla removed the two tabs connecting the battery cover and jar to the anode/cathode of the "jelly coil," replacing this with a spiral architecture. This change allows for many more connection points, increasing efficiency and reducing resistance. Tesla's new "dry electrode" technology cuts energy consumption and floor space by up to 10 times, offering significant savings and environmental benefits.
Tesla plans to reduce the volume and weight of its anode cells by replacing graphite with more efficient metallurgical grade silicon crystals. The company will add “new coatings” to the nickel in the cathode to provide cobalt-free stability. This in turn will lead to lower production costs.
The company aims to establish its own battery production in various parts of the world, next to its car factories. Tesla's CEO Elon Musk said Tesla will have factories producing its own cells in the US, Germany, and China.
So far, the California-based manufacturer has said its Roadrunner pilot line will be capable of producing about 10 GWh of batteries per year by 2021, making it the de facto 13th largest battery manufacturing facility in the world. Also yesterday, during the European Conference on Batteries, Musk said that 100 GWh of annual cell production is expected for the German battery plant, with a possible expansion to 200 to 250 GWh in the future.
