Silicon can store far more energy than graphite—the material used in the anode, or negatively charged end, of nearly all lithium-ion batteries.

Silicon-carbon batteries look like the solution to small battery capacity in Android phones, but there are two problems to overcome.

Of all the materials on the periodic table, silicon has the most promise as a full or partial replacement for graphite in the anode of lithium-ion batteries. Silicon has a theoretical charge ...

POWER: What’s the current status of silicon in the lithium-ion battery industry? Pluvinage: Currently, lithium-ion batteries predominantly use graphite for their anode electrodes. However ...

Scientists from the Department of Chemistry at Bilkent University in Ankara, Turkey, have analyzed lithium batteries using non-linear harmonic analysis and EIS. By comparing experimental measurements ...

Silicon-Reduced Graphene Oxide Self-Standing Composites Suitable as Binder-Free Anodes for Lithium-Ion Batteries. Self-standing silicon-based anodes (silicon-reduced graphene oxide, 40 wt.% of Si) ...

Researchers in China have used electrochemical impedance spectroscopy to analyze the state of health of sodium-ion batteries. Extracting four features from the measurements, they were able to create a ...

This story was updated on Dec. 27, 2022, to correct the amount of money silicon anode companies raised and the description of a Group14 Technologies factory.

The stable silicon-carbon composite material holds up to five times the capacity of graphite and affords up to 50% more energy density than conventional graphite for lithium-ion battery anodes.

With horizontally stacked cells that require less constraint in their packaging, Enovix's 100% silicon anode batteries are said to offer a big boost in energy per gram; i.e., longer battery life.

Silicon-carbon batteries accept and release lithium ions more quickly, allowing for safer and faster charging. Honor pushing this with an 80W charger on the China model of the Magic 6 Pro for the ...
