Tesla lately introduced an intention to make use of its all-new 4680-type cylindrical battery cells in battery power storage programs (BEES), just like the Megapack, Powerpack, or possibly even Powerwall.
The brand new sort of cell is at the moment used solely within the Tesla Mannequin Y produced in Texas (at the least a few of them, because the manufacturing unit additionally makes automobiles powered by 2170-type cells).
It is an fascinating factor, as a result of so far as we all know, the present Tesla in-house 4680 cells are primarily based on the NCM 811 cathode chemistry, whereas within the case of BEES, the corporate wish to make a transition from NCA/NCM to Lithium Iron Phosphate (LFP) battery chemistry.
If we perceive it accurately, the subsequent era power storage programs from Tesla could be LFP, however in a 4680 cell format. In any other case, if Tesla would follow the NCA or NCM, then there could be no transition to LFP. The third situation is a mixture of merchandise – 4680-type cells (NCA/NCM) in some merchandise, and prismatic LFP cells in some merchandise.
The information was shared by the way in which of the announcement of the new $3.6 billion funding on the Tesla Giga Nevada, which is able to convey 100 gigawatt-hours (GWh) battery cell manufacturing (4680-type) to the manufacturing unit. The plant already produces 37+ GWh of 2170-type cells yearly (in partnership with Panasonic).

Tesla Giga Texas: 4680-type battery cell manufacturing (Tesla This fall 2022 report)
100 GWh is a large quantity of batteries. Tesla estimates that it is sufficient for 1.5 million light-duty automobiles.
Alternatively, if the corporate plans to supply as much as 50,000 Tesla Semi per 12 months (sooner or later sooner or later), and one truck requires as much as 900-1,000 kWh of batteries (within the 500-mile vary model), then we’re speaking about 50 GWh/12 months for the Semi alone.
The remaining 50 GWh/12 months could be used for native manufacturing of battery power storage programs. Tesla may also require 40 GWh of batteries for its new Megapack manufacturing unit in Lathrop, California.
Within the long-term, the Giga Nevada plant would possibly produce as much as 500 GWh of 4680-type battery cells (it might require additional investments), whereas the corporate could be at 1,000 GWh/12 months globally. Tesla’s CEO Elon Musk hints that possibly it can even attain 2,000-3,000 GWh/12 months yearly sometime (excluding exterior suppliers).
Tesla Giga Nevada part two funding:
- $3.6 billion
- 4680-type cylindrical battery cell manufacturing
100 GWh/12 months initially (as much as 500 GWh/12 months sooner or later) - Tesla Semi manufacturing
- 3,000 extra jobs
The plant is already producing 2170-type cylindrical battery cells (in partnership with Panasonic) at round 37+ GWh/12 months, battery modules and packs, power storage merchandise, and drive models/energy electronics.
Up to now, the plant produced 7.3 billion battery cells, 1.5 million EV battery packs, 3.6 million drive models, and 1 million power storage modules (14+ GWh).
Tesla Giga Nevada part one funding:
- $6.2 billion
- 5.4 million sq. toes facility
- 11,000 staff
