Burned rice hulls could help batteries store more charge

New research finds hard carbon in rice hull ash, providing a cheap domestic source to replace graphite in batteries.

13-Dec-2024 - A closer inspection of ash from burned rice hulls, the hard outer layer of rice grains, revealed a form of carbon that could nearly double the energy density of typical lithium-ion or sodium-ion batteries. This sustainable source of 'hard' carbon, which outperforms ordinary graphite in battery ...

Researchers unlock the “silicate magic” for safer, cheaper, and more efficient batteries

Xiaowei Teng leads team eyeing new way of using iron to create high-performance energy storage

22-Oct-2024 - The world is rapidly transitioning to renewable power, but there are shortcomings. Solar power falls at night, and wind power recedes and ascends irregularly. New technologies need to be developed that can store energy from the electrical grid when there’s a surplus and deploy it when there’s not ...

Bubble findings could unlock better electrode and electrolyzer designs

A new study of bubbles on electrode surfaces could help improve the efficiency of electrochemical processes that produce fuels, chemicals, and materials

14-Oct-2024 - Industrial electrochemical processes that use electrodes to produce fuels and chemical products are hampered by the formation of bubbles that block parts of the electrode surface, reducing the area available for the active reaction. Such blockage reduces the performance of the electrodes by ...

A surprising way to jump-start battery performance

First charge determines lifespan of lithium-ion batteries

03-Sep-2024 - A lithium-ion battery’s very first charge is more momentous than it sounds. It determines how well and how long the battery will work from then on – in particular, how many cycles of charging and discharging it can handle before deteriorating. In a study published inJoule, researchers at the ...

Brushing thin films onto electrodes preserves batteries

A bit of brushing may be the secret to making better rechargeable lithium batteries

31-Aug-2022 - The Rice University lab of chemistJames Tourintroduced a technique to tune the surface of anodes for batteries by simply brushing powders into them. The powder adheres to the anode and becomes a thin, lithiated coating that effectively prevents the formation ofdamaging dendrites. A powder of ...
