Japan\'s Panasonic Corp. ranked second, with 18.7 percent of the market, followed by South Korea\'s LG Chem Co. with 17.5 percent, the report said. \"Last year, Samsung SDI improved its sales structure with a focus on lucrative products for smartphones and tablet PCs,\" Samsung SDI Chief Executive Officer Park Sang-jin was quoted as saying.

The report, quoting Samsung SDI projections, said the market for smaller batteries is expected to grow 9 percent this year in revenue terms, fueled by demand for mobile devices.
