  7. Abstract:
  8. Lithium-ion batteries are widely used in portable electronics and electric vehicles due to their high energy density and low weight. However, one of the major challenges these batteries face is dendrite growth during charge and discharge cycles. Dendrites can cause internal short circuits, reduce battery performance, and in extreme cases, lead to battery failure or even explosions. This research focuses on studying the growth of dendrites using phase-field modeling. The phase-field approach allows for a detailed simulation of lithium deposition on electrodes, evaluating the impact of factors such as surface roughness, applied voltage, electrolyte conductivity, and electrode spacing on dendrite formation. The findings reveal that increasing surface roughness and reducing the distance between the anode and cathode accelerate dendrite growth. Additionally, high applied voltages significantly influence dendrite formation. To improve battery performance and extend their lifespan, this study offers recommendations for controlling dendrite growth, including optimizing operational conditions and improving the design of electrolyte and electrode materials. This research contributes to advancing the safety and efficiency of lithium-ion batteries and offers valuable insights into developing more reliable and durable battery technologies for the future
