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. 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.
