It has been found that Samsung Electronics is using batteries supplied by Samsung SDI and Murata Manufacturing in its Galaxy S8 and Galaxy Note 8. The batteries have a capacity of 3,300 mAh and those from Samsung SDI account for 80% of the total supply.
Murata Manufacturing acquired the battery business unit of Sony last year. It is currently leading the global multilayer ceramic capacitor (MLCC) market.
Samsung SDI and Murata Manufacturing take the place of ATL, a Chinese battery supplier. ATL worked with Samsung Electronics for over 10 years, supplying its products for the Samsung smartphones including the Galaxy Note 7.
According to industry sources, the replacement was because of the explosions of the Galaxy Note 7. Samsung Electronics announced in January this year that defective batteries caused the explosions, saying that welding projections were abnormal, insulating tapes were not attached, and separation membranes were too thin.
After the scandal, Samsung Electronics adopted a stricter quality control process for smartphone batteries. The company is planning to keep using batteries supplied by Murata Manufacturing instead of ATL for its high-end phones to follow the Galaxy Note 8.
