Figure (b): Charge/discharge cycle characteristics of Li-ion battery capacity. The new C/Ge/C structure demonstrated a high capacity of 910 mAh/g, about three times that of conventional carbon, for ...
(Front row, from left) Dr. Daeho Kim and Dr. Jong Hwan Park of KERI have developed a groundbreaking process technology to ultrafast preparation of hard carbon, an anode material for sodium ion ...
Researchers reveal new mechanisms governing the storage and the movement of sodium ions in hard carbon nanopore anodes.
Long-term tests further show that the presodiated hard carbon retains 93.6% of its capacity after 3,000 charge–discharge cycles. Microscopic and spectroscopic analyses confirm the formation of a thin, ...
Turning plastic into solid carbon is not easy. Heat the polymers to rearrange their carbon atoms, and they decompose into light hydrocarbons and gases. But researchers at the US National Energy ...
Nanoengineered hard-carbon with nanoporous channels and an ultrathin SEI boosts fast, reversible all-slope sodium storage in hard-carbon anodes. (Nanowerk News) A research team from the Hefei ...
In a recent study published in Small, researchers introduced a three-dimensional, freestanding porous carbon nanofiber (PCNF) structure embedded with silicon oxide (SiOx), designed to address critical ...
