Key Preparation Technology for Hard Carbon-Based Composited Anode and Its Application in Sodium-ion Battery
Aim and Objective
This project aims to address the issues of limited capacity and high temperature in conventional hard carbon material preparation via inverse materials design and its experimental realization. Specifically, the goal is to develop a low-temperature macro-preparation technology for hard carbon, optimize its design, and create a new flame-retardant electrolyte for Na-ion batteries.
This will lead to a high-performance hard carbon-based sodium-ion battery system, contributing to sustainable large-scale energy storage solutions. The project combines the expertise of Polish and Chinese researchers to optimize hard carbon-based microstructure, study the intrinsic relationship between thermodynamic behavior and safety performance, and develop a low-cost, high-performance hard carbon anode material and soft pack sodium-ion battery.
