A new carbon material with Na storage capacity over 400mAh/g

Developing high-capacity carbon anode materials can further improve the energy density of sodium-ion batteries (NIBs). Recently, researchers from the Institute of Physics, Chinese Academy of Sciences (IOP-CAS), reported a ...

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 ...

Asphalt helps lithium batteries charge faster

A touch of asphalt may be the secret to high-capacity lithium metal batteries that charge 10 to 20 times faster than commercial lithium-ion batteries, according to Rice University scientists.

Researchers develop an efficient dual-ion battery design

Dual-ion batteries (DIBs) are a new type of battery developed in recent years, typically using graphite as both the cathode and anode material. DIBs can operate across a wider voltage window with safer performance, and are ...

Scientists power mobile phone using urine
