Recently, Hitachi ltd. and Tohoku University’s Advanced Institute for Material Research (AIMR) group have developed a basic technology to improve thermal durability in lithium-ion batteries, as reported by CrazyEngineers.com.
This basic technology reduces “the internal resistance of all-solid-state lithium-ion [batteries] using a complex hydride as a solid electrolyte,” the solid electrolyte being a LiBH4 based complex hydride, according to CrazyEngineers.com.
CrazyEngineers.com reports that the battery can “operate at temperatures as high as 150º Celsius”, although internal resistance reduction isn’t the only reduction – there is also an overall cost reduction due to the batteries not needing a cooling system.
However, this system still needs to be improved before commercialization. It is currently being developed under a project titled ‘Collaborative Research for Next Generation Innovative Battery’, according to CrazyEngineers.com.
