Article Synopsis
- Silicon-based anodes face challenges like low initial Coulombic efficiency (ICE) and durability problems, making them less effective in batteries.
- Traditional pre-lithiation methods can be unsafe due to unstable chemicals, highlighting the need for safer alternatives.
- This study introduces a lithium-enriched silicon/graphite material with over 110% ICE and excellent stability, achieved through a unique pre-storage method that enhances performance while remaining stable in air and water.
In order to understand the effects of different patterns of prefabricated fractures and grain size compositions on the fracture characteristics, acoustic emission characteristics and mechanical properties of the rock masses. We conducted compression shear experiments on square rock masses with different modes of prefabricated fractures and different grain size compositions. The experimental results showed that five fracture patterns were produced in specimens with different fracture patterns.

In this paper, the crack characteristics, mechanical characteristics, and acoustic emission characteristics of rock masses with different grain size compositions, different crack patterns, and different crack lengths were investigated under uniaxial compression. The rock masses were made of rock-like materials.
