costs 14% less per kWh than the 2170.

Fewer cells reduce assembly time, improve group efficiency, and further bring cost advantages.<\/p><p>Only the external dimension changes, the energy density can be increased by 10%; when the silicon carbon negative electrode is replaced, the energy density can be increased by 20% to more than 300wh\/kg.<\/p><h4 id=\"Cell-factory\">Cell factory<\/h4><p>Costs will be reduced by 18% as manufacturing processes are simplified, line efficiencies are improved, and processes are improved.

Overall, the large cylindrical battery can achieve continuous and uninterrupted production.<\/p><p>The manufacturing process is less than the soft case and the square aluminum shell (about 10 processes for a large cylinder). The production line time is short (about 7 days for large cylinders, about 10 days and 12 days for square and soft bags, respectively), which improves the turnover rate and reduces the inventory rate.<\/p><p><img fetchpriority=\"high\" decoding=\"async\" class=\"size-full wp-image-55346 alignnone\" src=\"https:\/\/www.takomabattery.com\/wp-content\/uploads\/2022\/10\/4680-battery-battery-performance-has-been-improved.jpg\" alt=\"4680 battery battery performance has been improved\" width=\"1000\" height=\"461\" srcset=\"https:\/\/www.takomabattery.com\/wp-content\/uploads\/2022\/10\/4680-battery-battery-performance-has-been-improved.jpg 1000w, https:\/\/www.takomabattery.com\/wp-content\/uploads\/2022\/10\/4680-battery-battery-performance-has-been-improved-300x138.jpg 300w, https:\/\/www.takomabattery.com\/wp-content\/uploads\/2022\/10\/4680-battery-battery-performance-has-been-improved-768x354.jpg 768w, https:\/\/www.takomabattery.com\/wp-content\/uploads\/2022\/10\/4680-battery-battery-performance-has-been-improved-600x277.jpg 600w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" \/><\/p><h2 id=\"4680-battery-cell-manufacturing-process\">4680 cell manufacturing process<\/h2><ul><li>\u00a0<strong>Coating process<\/strong><\/li><\/ul><p>Dry electrode technology production equipment occupies 10 times less floor space, 10 times less energy consumption, and 10%-20% less cost.

The water cooling area per kWh of the 4680 batteries is 1.64 times that of a square and 1.53 times that of a soft pack.<\/p><p>Electrodeless ears further improve heat dissipation. The tesla 4680 battery adopts the all-pole\/non-pole-lug scheme, that is, the metal tabs that are drawn and connected from each layer are removed, and the two ends of the battery are directly changed to conductive materials, so that they can directly transmit current.<\/p><p>While the battery has become larger, the current path is shorter. Reduced from 250 mm to 50 mm, the current conduction area is larger, and the impedance is greatly reduced, making the temperature rise of high current charging and discharging smaller.<\/p><p>The 4680 greatly increases the heat dissipation area of the battery cell, and the heat transfer is more uniform, and the ternary material that is more sensitive to safety is more attractive.<\/p><h2 id=\"4680-battery-lead-technological-changes\">Tesla 4680 battery lead technological changes<\/h2><p>After the cost reduction of the ternary 4680 cylinder, the cost is similar to that of the iron-lithium square, and the safety is also improved.

The influence of the single thermal runaway is small, and the pressure relief direction is controllable.<\/p><p>The superimposed full-pole design makes the ternary 4680 cylindrical with low heat generation and difficult thermal management.

The production process needs to overcome the following major difficulties:<\/p><ol><li>The size consistency should be high. The casing is a precision structural part, which is sensitive to dimensional tolerances, and the battery level requires a hundred-level accuracy requirement;<\/li><li>The thermal diffusion requirement is high. Steel needs to meet the requirements of thermal diffusion. Compared with aluminum, steel has higher hardness and poorer ductility, so it cannot be directly manufactured using the process parameters of cans;<\/li><li>The height of the battery may continue to increase.<\/li><\/ol><p>From the perspective of battery overcurrent and heat generation, the height of the battery may be further increased, and the casing process needs to be compatible with long battery casings. Efficient production is a key element for horizontal stamping into the field of tesla 4680 battery housings.<\/p><p>The 4680 cell has inherent advantages using the CTC process. First of all, CTC has certain requirements on the structural strength of the battery. The battery itself has to bear considerable mechanical strength.<\/p><p>Compared with 18650 and 21700, the 4680 has higher structural strength, and the outer casing is generally made of stainless steel.
