STATIONARY GRID-SCALE ENERGY STORAGE BATTERIES

SPECIALTY THERMOPLASTICS HELP ENERGY STORAGE BATTERIES DELIVER RELIABLE PERFORMANCE AND EFFICIENCY FOR POWER GRIDS

Designers require materials that can retain excellent electrical and
mechanical properties in a demanding electrolyte environment.

Batteries used for stationary, utility-scale energy storage are a critical component of power grids, especially systems that use renewable energy sources such as solar and wind. Many energy storage systems use lithium-ion and flow batteries. Because these batteries incorporate electrolytes containing harsh or corrosive chemicals, their components must provide robust resistance.

Specialty materials from SABIC can withstand degradation from exposure to corrosive electrolytes, helping to ensure battery reliability, efficiency and long service life. LNP™ STAT-KON™ compounds and NORYL™ resins provide excellent chemical resistance and other desirable properties, making them good candidates for energy storage battery components. Potential applications include conductive electrodes, terminal ends, housings and fluid management components such pumps, valves, and tanks for electrolyte handling. In addition, SABIC can optimize material properties further to meet specific application requirements.

Compounding Expertise You Can Rely On

LNP compounds are formulated by melt blending different base resins with reinforcements and additives to deliver targeted properties such as conductivity, thermal management and EMI/RFI shielding.

SABIC introduced the first LNP conductive compounds to market in 1974 and has steadily expanded this conductive portfolio since then.  The latest addition to the LNP compound family? Low resistivity conductive compounds.

LOW RESISTIVITY LNP™ STAT-KON™ COMPOUNDS IN CONDUCTIVE COMPONENTS

Low volume resistivity (<2 ohm-cm) LNP STAT-KON compounds are well suited for conductive electrodes and terminal ends in energy storage batteries. Besides excellent chemical resistance to help withstand corrosive electrolytes, they offer the following:

• Good ductility and mechanical performance

• Melt processability into thin sheets using conventional extrusion equipment

• Streamlined processing vs. metal through elimination of secondary operations

• Lighter weight than metal, contributing to ease of battery handling

NORYL™ RESINS IN BATTERY COMPONENTS

NORYL resins are formulated by blending PPE with PS, nylon, PP or TPE. The excellent chemical resistance of these materials combined with the below properties make NORYL resins well suited for use in battery housings as well as fluid management components such as pumps, valves, and tanks for electrolyte handling.

Thanks to its high modulus and inherent stiffness properties, unreinforced NORYL resin can potentially replace materials that require glass fiber reinforcement to achieve a high level of stiffness. Elimination of glass fibers can improve isotropic dimensional stability, facilitate molding of complex parts and make it easier to join parts using heat staking and ultrasonic and hot plate welding.
