Expanding the temperature range of lithium-ion batteries

Electric cars struggle with extreme temperatures, mainly because of impacts on the electrolyte solutions in their lithium-ion batteries. Now, researchers have developed new electrolytes containing multiple additives that ...

Upcycling plastic bags into battery parts

Plastic bag pollution has become a huge environmental problem, prompting some cities and countries to heavily tax or ban the sacks. But what if used plastic bags could be made into higher-value products? Now, researchers ...

Covalently modified two-dimensional arsenic

The discovery of graphene, a material made of one or very few atomic layers of carbon, started a boom. Today, such two-dimensional materials are no longer limited to carbon and are hot prospects for many applications, especially ...

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 ...

Microwaved plastic increases lithium-sulfur battery life span

Purdue engineers have figured out a way to tackle plastic landfills while also improving batteries – by putting ink-free plastic soaked in sulfur-containing solvent into a microwave, and then into batteries as a carbon ...
