About five years ago, Huang discovered crumpled graphene balls — a novel type of ultrafine particles that resemble crumpled paper balls. The particles are made by drying tiny water droplets with ...

Indeed, crumpled paper ball-like graphene particles have scalable Li loading up to 10 mAh cm−2 within tolerable volume fluctuation. High Coulombic efficiency of 97.5% over 750 cycles (1,500 hr) was ...

The crumpled balls can move apart when lithium deposits and then readily assemble back together when the lithium is depleted. Because miniature paper balls are conductive and allow lithium ions to ...

How often have you crumpled a sheet of paper in frustration and thrown it into the bin without further thought? You'll be amazed to hear that researchers - inspired by a trash can full of crumpled-up ...

The addition of crumpled graphene balls to lubricant oils causes a 15% fall in friction and the same degree of reduction in metal surface degradation. Even better, a low concentration of these ...

Crumpled Graphene Balls Stabilized Dendrite-free Lithium Metal Anodes. Joule, 2018; 2 (1): 184 DOI: 10.1016/j.joule.2017.11.004 ...

Self-dispersed crumpled graphene balls in oil for friction and wear reduction. Proceedings of the National Academy of Sciences, 2016; 201520994 DOI: 10.1073/pnas.1520994113 ...

The solution lies in a scaffold made from crumpled graphene balls, which can stack with ease to form a porous scaffold, due to their paper ball-like shape. They not only prevent dendrite growth ...

(Nanowerk News) When an automobile’s engine is improperly lubricated, it can be a major hit to the pocketbook and the environment. For the average car, 15 percent of the fuel consumption is spent ...
