High-modulus solid sodium silicate (modulus 3.2–3.5) is widely adopted in lithium-ion power batteries, with prominent functional strengths as below:
一、Excellent high temperature resistance
It maintains stable physical and chemical properties under extreme heat, effectively resisting thermal runaway risks inside batteries, improving overall thermal safety and service stability of battery cells.
二、Strong bonding adhesion
Forms compact and firm adhesive layers on battery separators and silicon-carbon anodes. It tightly fixes internal materials, avoids peeling and loosening during repeated charge-discharge cycles, prolonging battery cycle life.
三、Outstanding electrolyte corrosion resistance
Hardly reacts with internal battery electrolyte, keeps structural integrity for long-term use, prevents performance attenuation caused by chemical erosion.
四、Good insulation & isolation effect
Possesses fine insulating property, effectively isolates positive and negative electrodes, reduces short-circuit probability, enhances battery operational safety.
五、Low moisture absorption & stable storage
Solid form features low water absorption, not easy to deteriorate during transportation and production processing, ensures consistent batch quality of finished batteries.
六、Cost-effective eco-friendly material
Non-toxic and harmless raw material, compatible with mainstream battery production processes. It partially replaces expensive organic binders, cutting production costs while meeting industrial environmental requirements.
