4680 Battery Cells. The 4680 battery cell is named for its 46 mm diameter and 80 mm length. Tesla unveiled the 4680 cells at its Battery Day event in September 2020, marking a departure from the smaller 21700 and 18650 cells Tesla had previously used in its vehicles. Currently, 4680 cells are powering both the Cybertruck and Model Y.
1 天前· The above estimates are also in line with the plan mentioned by Musk when he released the 4680 battery concept on Battery Day: "4680 battery production will reach 100GWh a year in 2022 and 3TWh a year in 2030. 4680 battery silicon-based anode demand is about 56,000 tons. The 4680 battery uses a silicon-based negative electrode material.
The 4680 battery (46mm in diameter and 80mm in axial length) offers higher energy and power advantages compared to commonly used 18650 or 21700 cylindrical cells.
Before the 4680 battery, silicon-based materials have actually been added to the negative electrode scheme in a small amount by some manufacturers. For example, 5%

It uses three cutting-edge technologies: CTC technology (a technology that mounts cells directly to the chassis), 4680 cells and one-piece die-casting, which significantly reduces the difficulty and cost of assembling
At the end of 2023, the 4680 battery chemical composition ratios in Cathode material was NMC 811 (80% Nickel, 10% Lithium, 10% Cobalt). However, Tesla is finishing the process of transitioning over to NMC 955 now that we are in 2024. They are also trialing asymmetric lamination with one side of the laminated material thicker than the other.
The reason behind that is most likely the necessity to carry forces in a structural battery pack. It makes the 4680-type cell heavier. According to the video, the weight penalty is estimated at 10-15%. 2170-type: 125-250
The 1GWh 4680 battery consumes about 750 tons of silicon-carbon anode materials, and the demand for silicon-based anodes for the 4680 battery is expected to be about 56,000 tons. On February 19, Tesla announced that it has produced 1 million 4680 batteries in its pilot plant in California.
The elegant design allows for a simple flow of electrons to actively pass without causing an increase in heat. Image used courtesy of Tesla. The anode of the 4680 battery utilizes raw metallurgical silicon which unlike industry used silicon the structure of the material does not crack when energy is passing through.
4680 battery silicon-based anode demand is about 56,000 tons The 4680 battery uses a silicon-based negative electrode material. Compared with graphite, the typical negative electrode material of lithium batteries, the intercalation of silicon for lithium is 9 times that of graphite, which is more abundant on earth.
It appears to be an NCM 811 chemistry with very good energy density and total energy estimated at 96-99 Wh. In the second part of the Tesla 4680-type cylindrical battery cell teardown and analysis, The Limiting Factor presents the initial specs and findings.
In essence, after all, 4680 battery is a large-size container. Since it can be filled with ternary lithium, it can naturally be filled with lithium iron phosphate, and even further reduce costs. It can also be seen from the current trends of major battery manufacturers that many parties in the industry chain are actively developing 4680 batteries.
With the new 4680 cylindrical cells, the high system voltage is achievable in typical packs even with parallel connection of 3 to 5 cells. In addition to the 4680 cell originally announced by Tesla, other formats are now under discussion, ranging from a height of 40 mm to 120 mm.
