Samsung SDI Pacing Cylindrical Battery Development

According to the media reports, Samsung SDI (Samsung digital Interface) has expanded its cylindrical battery production lines in Cheonan, Korea, and Malaysia.

These batteries are 46mm in diameter, and their rumored height is 80mm. These batteries, named 4680-type, would increase energy density five times and output six times. Hence it could be a breakthrough.

According to rumors, another smaller battery is in production at 40-60 mm. Even though rivals LG energy solutions, Panasonic, TESLA, and other manufacturers will agree on a standard size for unification.

Currently, the SDI makes D21 H70mm and D18 H65 mm type batteries

Currently, Tesla makes Type 4680 batteries, and other companies like Panasonic are speeding up their game; this could mean that Samsung and Tesla could work together soon.

According to research conducted by SNE a market research firm specializing in energy, the electric vehicle (EV) market will grow by 27 % in 2030 from 19 % this year. Currently, SDI is expanding its production in Cheonan, Korea, and Malaysia.
