The word "unblowuppable" is thrown around a lot these days, particularly when it comes to smartphones. No OEM wants to put the next Galaxy Note 7 on store shelves… especially not Samsung not after what happened with both the original batch of Note 7 phones and the "safe" ones they shipped out later. Samsung has already taken steps to ensure that the devices it manufactures are safe, like implementing a more rigorous battery testing process. Now they're also looking at safer alternatives to the lithium-polymer batteries that they're using today. According to a report from Korea Herald, Samsung SDI will be ready to ship solid-state lithium batteries within the next two years. Solid-state batteries have a number of advantages over conventional lithium-ion ones. First and foremost is the fact that they're inflammable they don't catch fire easily. They're also more energy-dense and have much longer life spans — up to five times as long.
