Keytech Project

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.

Project Timeline Proposal

Specific Objectives

High-throughput screening of metal-based catalysts to lower hard carbon graphitization potential and achieve microstructure modulation and low-temperature macro-preparation.
Improve sodium storage capacity of hard carbon through heterogeneous atom doping and in situ composite hybridization, optimizing electrochemical performance.
Modify electrolytes at a molecular scale to enhance stability, voltage window, ionic conductivity, and mechanical strength, ensuring stable operation of high safety and high-performance sodium-ion batteries.
Design and prepare low-temperature hard carbon composite negative electrodes, construct high-specific energy soft pack batteries, and assess the connection between thermodynamic changes and battery safety and cycling stability.
