Samsung SDI potentially might become another supplier of the 4680-type cylindrical battery cells for Tesla, like Panasonic and LG Energy Solution (rumor).<\/p>\n

According to The Elec<\/em>‘s unofficial sources, Samsung SDI is developing various versions of the 4680-type batteries, or rather cylindrical cells with a diameter of 46 mm and different heights.<\/p>\n

Besides the base form factor of 4680 (46 mm in diameter and 80 mm tall), reportedly the company works also on a shorter version with a length between 40 mm to 60 mm.<\/p>\n

According to the article, the company might target other customers\/applications, which require shorter cells (or maybe a double battery stack).<\/p>\n

Important is that the diameter would remain the same, probably to be able to produce both types with minimal changes to the production line.<\/p>\n

We don’t know whether the rumors are true. Currently,\u00a0Tesla produces 4680-type battery cells in-house in the US<\/a>, while Panasonic officially admits that it was asked to speed up development.<\/a><\/p>\n

The Korea Herald<\/em><\/a> reported about 4680-type battery cell development by South Korean Samsung SDI and LG Energy Solution in 2021. Actually, in February 2021, we heard a rumor that LGES is going to build a pilot production line<\/a>.<\/p>\n

In other words, major battery manufacturers are very likely actively looking into the new cell format to maybe do business with Tesla<\/a> – the world’s largest electric car manufacturer and lithium-ion battery consumer.<\/p>\n

We are curious whether smaller cells – 46(40-60) – have something to do with other manufacturers. For example, CATL is expected to supply BMW with cylindrical lithium-ion battery cells<\/a>. Samsung SDI also is a battery supplier for BMW (prismatic cells).<\/p>\n

If the German manufacturer really has decided to switch to a new cylindrical form factor, then the necessity of diversification of the supply chain would probably mean orders of cylindrical cells from at least 2-3 battery manufacturers, including Samsung SDI.<\/p>\n

Overall, the 4680-type battery topic already has been ongoing for a few years, since Tesla announced the new type in September 2020. Soon, we should hear something about the investment plans, other than Tesla’s production in Texas and in Germany.<\/p>\n
