Samsung is reportedly preparing a pilot line to produce Tesla's 4680 battery, which will have an annual capacity of around 1 GWh for the pilot line, but increase to 8 - 12 GWh over time, according to Samsung.
Samsung SDI is preparing to set up a pilot line at its plant in Cheonan, South Korea, to test production of batteries to be supplied to Tesla, according to technology media outlet The Elec. The source said the cells are 4680 cylindrical cells. The South Korean company will test the production of these cells throughout the year.
The sources also said that Samsung SDI is preparing at least two versions of the cells, one of which is less than 80 mm long, a measure that could be aimed at supplying batteries to customers other than Tesla.
The pilot line being prepared in Cheonan, Korea, has an annual production capacity of just under 1 GWh and a production rate of 20 ppm. the goal is to increase production to 200 - 300 ppm, equivalent to 8 - 12 GWh of annual production capacity. The mass production line is expected to be built at the Samsung SDI battery plant in Seremban, Malaysia.
The Korean company Hanwha Group (Hanwha) will supply the electrode equipment. In addition, the company aims to provide roll presses and slitting machines whenever possible. South Korea's Koem Electronic Materials Co. will provide winding machines and assembly equipment. Hanwha and Koem are also supplying equipment for Tesla's 4680 battery pilot line in Fremont, California, according to the report.
