Improved production process with new spheroidization machine with high efficiency and low energy consumption for rounding natural graphite for Li-ion battery applications

Lithium Intercalation Kinetics and Fast‐Charging Lithium‐Ion Batteries: Rational Design of Graphite Particles Via Spheroidization

“…All these parameters can be varied within a certain range, depending on the equipment used. [17,[19][20][21] The energy input during the process depends on these process parameters: in general, longer milling times, higher rotation speeds, and smaller batch sizes correspond to higher specific process energy. [19,20] For the present work, five natural and five synthetic graphite samples have been prepared by using different set of process parameters.…”

The relative specific process energy calculated for the shaping of the samples is reported in Supporting Information (Figure S1 and Equation S1, Supporting Information).…”

Spent graphite from lithium-ion batteries: re-use and the impact of ball milling for re-use

“…As reported, the x 50 of final products can range from 12.5–20.5 μm. 14 Apart from the spheroidization, commercial graphite anodes generally have to be pre-lithiated before use in Li-ion batteries, or pre-lithiated in situ during the formation cycle. The pre-lithiation process not only compensates for the Li ion loss due to solid electrolyte interface (SEI) formation but provides a stable redox potential for the anode.…”

An effective model for sodium insertion in hard carbons

“…Sodium ion batteries (NIBs) are a potential alternative to LIBs because NIBs have similar electrochemical properties to LIBs but at a much lower cost since Na is an Earth abundant material. 3,4 Unfortunately, graphite, the traditional anode of LIBs [5][6][7][8][9] is not suitable for NIBs 10 because of low capacity 3 and high volume expansion. 11 Among several anodes for NIBs, such as MXenes, 3 C 6 B 4 , 12 blue -phosphorene, 13 and 1H-BeP 2 , 14 hard carbon (HC) is a promising anode for NIBs because of stable cycling, large specific capacity, 15 and low-cost biomass product precursors.…”
