Samsung could offer explosion proof batteries for mobiles within two years

03 July 2017

In a report dated June 30, the Korea Herald said that Samsung SDI will be able to produce solid-state batteries within the next two years, posing far less of a fire or explosion risk than the current generation of lithium-ion batteries. The report, quoting an unnamed Samsung SDI executive, said initial use would likely be for mobile phones, with solid-state batteries for cars further down the line.

These batteries contain solid electrolytes, whereas li-ion batteries contain liquid electrolytes that can ignite or explode when the liquid leaks and is exposed to air or water.

The executive told The Korea Herald on condition of anonymity: "Our technological level to produce a solid-state battery for smartphones will be mature enough in one to two years. However, it depends on Samsung Electronics whether it will be used for phones."

He also said he thought rival LG Chem had reached a similar stage in developing solid-state batteries.

As for use in cars, he said more time was needed to conduct stricter safety checks, with a possible introduction date of 2025.

This comes following a series of battery fires and explosions affecting smartphones, including Samsung’s Galaxy and Apple’s iPhone range. Last year, Samsung discontinued the Galaxy Note 7 after a string of battery explosions, costing the South Korean giant at least $5.3 billion dollars in recall costs and damages.
