Lithium ion batteries may benefit from porous amorphous

2016-10-11  Next-generation anodes for lithium ion batteries will probably no longer be made of graphite. Silicon, which is a related material, can provide a much higher capacity than graphite, but its crystallinity poses problems. In the journal Angewandte Chemie, Chinese scientists have introduced a porous silicon form that is amorphous, not crystalline, and has the potential to outstrip the other .

The Fascinating Uses of Graphite in Everyday Life

Amorphous graphite is preferred as it leaves a dark streak on paper. Finer the powder, darker the smear. In case the graphite is flaky, the smear loses its darkness. It is used in several lubricant products, such as grease and forging lubricants. In applications where high amounts of ash is preferred, amorphous graphite

Amorphous Phosphorus/Nitrogen-Doped Graphene Paper

2016-02-29  As the most promising anode material for sodium-ion batteries (SIBs), elemental phosphorus (P) has recently gained a lot of interest due to its extraordinary theoretical capacity of 2596 mAh/g. The main drawback of a P anode is its low conductivity and rapid structural degradation caused by the enormous volume expansion (>490%) during cycling.

Herein, we report a new ion storage mechanism for high-performance NDIBs using amorphous carbon (AOMC) as cathode. Unlike the graphite carbon that can only accommodate the PF 6 − anion (typical DIB system), the AOMC herein can both accommodate Na + cation and PF 6 − anion due to its amorphous feature, which is conceptually new dual-ion system for achieving much higher capacity.
