Solidion develops lithium battery that can be charged in five minutes

Solidion (STI) Technology announced that its battery scientists have successfully developed a cost-effective strategy for enabling completion of charging in 5 minutes for a wide range of lithium batteries. The technology uses a graphene-based heat spreader to quickly move heat from a battery to warm it up before or during fast charging. It also has a cooling system that kicks in when the battery is in use, like when powering a device or electric vehicle. The heat spreader moves the heat to the cooling system for efficient cooling. The system switches between heating when charging and cooling when discharging. Graphene, with its super high thermal conductivity, is much more effective than copper, which has a lower conductivity and is four times heavier. Solidion is aimed at fully commercializing this technology in 2-3 years.
