Nanotubes may give the world better batteries

Rice University scientists are counting on films of carbon nanotubes to make high-powered, fast-charging lithium metal batteries a logical replacement for common lithium-ion batteries.

A lightweight carbon nanofiber-based collector

Quan-Hong Yang from Tianjin University and Wei Lv from Graduate School at Shenzhen, Tsinghua University with their co-workers reported a lightweight, high-level nitrogen-doping carbon nanofiber framework as the current collector ...

Researchers design dendrite-free lithium battery

By designing a solid electrolyte that is rigid on one side and soft on the other, researchers have fabricated a lithium-metal battery that completely suppresses dendrite formation—a major safety hazard that can cause fires ...

Technique to suppress dendrite growth in lithium metal batteries

A team of researchers at Tsinghua University (Beijing, China) has reported an implantable solid electrolyte interphase (SEI) in a lithium metal anode. This stable SEI film can suppress lithium dendrite growth to realize safe ...

Safe lithium-metal batteries with graphene

Recently, researchers at Tsinghua University, China have proposed a graphene-based nanostructured lithium metal anode for lithium metal batteries to inhibit dendrite growth and improve electrochemistry performance. They report ...

Room-temperature lithium metal battery closer to reality

Rechargeable lithium metal batteries have been known for four decades to offer energy storage capabilities far superior to today's workhorse lithium-ion technology that powers our smartphones and laptops. But these batteries ...

'Stealth' nanoparticles could improve cancer vaccines

Cancer vaccines have recently emerged as a promising approach for killing tumor cells before they spread. But so far, most clinical candidates haven't worked that well. Now, scientists have developed a new way to deliver ...
