Graphene Silicon Nanoplatelets Increase Lithium-Ion Battery Capacity 4 Fold

Six months ago, Northwestern University professor Harold Kung theorized that, using a graphene–silicon mixture, there was a way to extend a new lithium-ion battery’s charge by 10 times and increase its lifespan by a factor of 10. The technology theorized by Harold Kung could allow for cell phone batteries to be charged in 15 minutes and hold a week’s worth of charge. It could also allow greater range and faster recharging for electric vehicles. At the time, he believed that silicon-graphene technology would be commercially viable in 3 to 5 years.
I’ve got a surprise for you. XG Sciences has announced the immediate availability of a graphene-silicon additive for lithium-ion batteries in commercial scale quantities. These graphene nanoplatelets will allow lithium-ion batteries to hold four times the amount of energy and extend the lifespan of the batteries substantially. This technology holds great potential for extending the range of electric vehicles, increasing the time between charges for portable consumer electronic devices, decreasing the weight of portable electronic devices, and decreasing the cost for the storage of electrical energy from solar cells for nighttime usage.
