New research has identified a nanostructure that improves the anode in lithium-ion batteries. Instead of using graphite for the anode, the researchers turned to silicon: a material that stores more ...

Silicon has long been seen as a promising anode material for next-generation lithium-ion batteries because it can store much more lithium than graphite. But silicon also expands and contracts sharply ...

A sponge-like silicon material could help lithium-ion batteries run longer on a single charge by giving the batteries' electrodes the space they need to expand without breaking. The lithium-ion ...

Researchers in India demonstrated that ion beam implantation enables precise boron doping in silicon solar cells, reducing defects and improving charge transport. The proposed approach could support ...

Lithium-ion batteries are the most popular secondary batteries for these applications, and silicon is widely regarded as the best anode material for lithium-ion batteries, particularly solid-state ...

Researchers at Rice University and Lockheed Martin may have developed a low-cost method of creating longer-lasting, high-capacity lithium-ion batteries. Currently graphite is used as the anode in ...

For years, scientists and engineers predicted that lithium-ion batteries would get a boost if they could just add more silicon. In the lab, the prediction held, but only for a short period of time.

(Nanowerk News) We can look through glass, but what glass itself looks like on the inside has so far remained a mystery - at least as far as the precise position of the atoms is concerned. Scientists ...
