Battery energy storage systems

Build passive thermal protection into every battery boundary.

Siltherm develops thin microporous barriers for the points where heat can move from one battery zone to the next.

Protection across the system

Place the barrier where the heat path must be interrupted.

A cell gap, module frame and enclosure interface do not need the same barrier. Siltherm configures the format for the position being protected.

Enclosure boundary

Carry protection through the enclosure

Door, wall, roof and rack interfaces can each receive a format matched to their geometry and access requirements.

Module boundary

Preserve space between modules

Thin barriers add thermal resistance around module frames while respecting compression, clearance and assembly space.

Repeat protection across the rack

Repeatable formats help carry the protection concept through joints, tolerances and serviceable rack positions.

Application map

Choose the protection position before choosing the format.

Choose the position first. The available gap and protected objective then define the barrier format.

Read the BESS engineering perspective
01 / Cell interface

Add resistance in the shortest heat path.

Ultra-thin barriers fit between adjacent cells while accommodating the required compression and electrical boundary.

Best suited to cell-to-cell interfaces
02 / Module boundary

Extend protection across the module.

Configured geometry maintains coverage around frames, busbars, supports and local clearances.

Best suited to repeated module interfaces
03 / Rack boundary

Make the concept repeatable and serviceable.

Panel layouts account for joints, penetrations and installation tolerance across repeated rack positions.

Best suited to rack-level protection zones
04 / Enclosure boundary

Protect the enclosure and adjacent equipment.

Rigid and configured barriers support protection around the enclosure, ventilation paths and surrounding interfaces.

Best suited to container-level integration

Engineering confidence

Carry the material performance into the battery assembly.

Siltherm takes the selected material into the intended battery geometry so the barrier can be evaluated in the real assembly.

Select a product route around the available space.

Compare Silthin and Panel FP for the protection zone and available installation space. Application-specific requirements can be reviewed with our engineering team.

Application and custom requirements

Discuss your storage system's thermal protection.

For product selection or custom components, describe the cell, module, rack or enclosure location, available dimensions, installation constraints and protection target. Leave your contact details for an application review. Confidential drawings can follow through an agreed project channel.
