Samsung’s SDI department which develops and manufactures Li-ion batteries, is planning to apply a capacity increase technology used for its electric car cells, to smaller ones meant to go in Samsung smartphones or tablets. The so-called “stacking” method is a way to package the battery components like the electrodes and electrolyte tighter for increased energy density.
By utilizing the stacking method for all of its batteries, Samsung SDI will be able to go head-to-head with its local rival LG Energy which also employs such technology, as well as the Chinese juggernauts ATL and BYD.
Two Korean companies reportedly bid to enter a partnership with Samsung over the stacked small cells development and production, but Samsung ultimately chose a pair of Chinese rivals for the joint venture.
