Description

Product Overview

Our resin-based hard carbon is synthesized primarily from phenolic resin and epoxy resin precursors,delivering electrochemical performance comparable to biomass-derived hard carbon while offering superior batch-to-batch consistency—making it a commercially viable solution for sodium-ion battery applications.Phenolic resin,in particular,demonstrates exceptional potential among hard carbon precursors due to its high carbon yield and favorable reversible capacity,and has been widely adopted by leading industry players.

Resin-Based Hard Carbon

Key Advantages

Unmatched Consistency&Controllability
Synthetic resins are chemically homogeneous with minimal batch-to-batch variation,ensuring product consistency and structural reproducibility far superior to biomass-based hard carbons.This makes our material ideal for large-scale production where uniformity is critical.
Ultra-High Purity&High Capacity
Synthesized from resin precursors with extremely low impurity content,delivering high specific capacity output.
Tailorable Initial Coulombic Efficiency(ICE)
Through pore-forming agents and crosslinking modification strategies,the ICE of phenolic resin-based hard carbon can be precisely engineered to meet specific application requirements.
Excellent Mechanical Strength
The carbon skeleton derived from phenolic resin exhibits high single-particle strength(250–400 MPa)after high-temperature carbonization,effectively resisting volume expansion during charge–discharge cycles and maintaining electrode structural integrity.
Highly Tunable Structure
By adjusting the degree of polymerization,crosslinking density,and carbonization parameters,we precisely control interlayer spacing,pore structure,and specific surface area to achieve targeted sodium storage performance optimization.

FAQ

Q1:How does resin-based hard carbon compare to biomass-based hard carbon?
Resin-based hard carbon offers significantly better batch-to-batch consistency and structural reproducibility,higher purity,and superior mechanical strength(250–400 MPa),while delivering comparable electrochemical performance.However,biomass-based variants may have a slight cost advantage.
Q2:Can this material be used in both sodium-ion and lithium-ion batteries?
Yes.It is primarily designed for sodium-ion anodes but also performs exceptionally well in lithium-ion systems,including high-rate power batteries and fast-charging applications up to 30C.
Q3:What makes phenolic resin a preferred precursor?
Phenolic resin offers high carbon yield,good reversible capacity,tunable pore structures through chemical modification,and excellent mechanical properties after carbonization.
Q4:How is the initial Coulombic efficiency controlled?
ICE can be tailored through the addition of pore-forming agents,crosslinking modification,and precise control of carbonization parameters,allowing targeted optimization for specific applications.
Q5:What is the recommended storage condition and shelf life?
Store in a dry,well-ventilated environment away from moisture and contaminants.Shelf life is 12 months under sealed,vacuum-packed conditions.Once opened,use within 48 hours and reseal immediately under vacuum.
