LG Chem said Tuesday that it’s been producing curved batteries since July this year at its plant in the Chinese city of Nanjing. “We’ve successfully developed batteries that haven’t existed before with our own patents, and that advancement is going to help us take the lead over our rivals in the race for next-generation digital devices,” said Kwon Young-soo, president of the company’s battery division.

The executive continued, “This is one of the greatest achievements for us. LG Chem will expand our leadership in small-sized batteries as well as continue our expansion in being the ongoing leader in car batteries and those for energy storage solutions.”

The firm said these curved batteries are already being used to power G2 smartphones manufactured by LG Electronics, the group’s consumer electronics affiliate. LG Electronics isn’t the only one that has shown interest in adopting curved batteries for upcoming flagship models as LG Chem is preparing to sell the products to other smartphone vendors, said a company spokesman Owen Sung.

Scientists build bendable battery

A group of Korean scientists has developed the world’s first bendable lithium-ion batteries that will aid in the development of flexible mobile devices and the efficiency of rechargeable batteries.

According to the Ministry of Education, Science and Technology yesterday, a joint research team led by Professor Lee Sang-young of the Ulsan National Institute of Science and Technology and researchers from nine other institutes succeeded in developing imprintable, fluid-like polymer electrolytes that are used for lithium-ion batteries.

Conventional batteries use liquefied electrolytes and are put into square-shaped cases, which make them inflexible. There are also risks of explosion. Because of these disadvantages, there have been efforts to develop high-molecule electrolytes. The use of fluid-like electrolytes not only makes the battery bendable but also more stable, the Science Ministry said, which partly funded the research.
