Nano graphite produced by rapid grinding as an anode for lithium-ion batteries

Javed Karim, Asan Ronie

Reducing the particle size of active materials is an effective solution to the performance
degradation of lithium-ion batteries. In this study, we proposed a simple strategy for
preparing Nano graphite as the anode of lithium-ion batteries by the rapid mechanical
grinding method. Diamond particles have been selected as the medium for the first time
to achieve high processing efficiency and low energy consumption. The 10-300 nm Nano
graphite produced in this way exhibits an intact structure and a high specific surface area.
The introduced oxygen atom increased the wettability of the Nano graphite electrode
and reduced its polarization. Nano graphite produced after 3 hours of grinding shows
an excellent reversible capacity of 191 mAh g-1 at a rate of 5 C after 480 cycles, with an
86% increase in capacity at 1 C compared to pure graphite[1,2]. The culmination of this
strategy is the optimization of current manufacturing methods. Excellent electrochemical
performance results from the combined effect of Nano scale particle size, large specific
surface area, and continuous mesopores. Foreword ion battery (LIB), which is one of the
indispensable energy storage devices in the world of production and daily life, has various
merits such as high average output voltage and high energy density. Environmentally
friendly. Li + intercalation / DE intercalation plays an important role in the storage and
release of electrical energy converted from the chemical energy stored in the compound,
forming a solid engineering foundation for LIB. LIB performance assessments are based
on several key indicators such as charge and discharge capacity, lifespan, and rate
performance.
