Duty cycle

What traction duty demands of a separator

Motive power is the hardest duty cycle in lead-acid: daily deep discharge, high-rate loads and long strings. This series is designed around a high specific surface area (BET ≥ 1.6 m²/g) that binds electrolyte tightly to the fiber matrix, resisting stratification and dendrite penetration through thousands of partial cycles.

A thin sheet (0.5–1.2 mm at 100 kPa) with 215 ±10 g/m²·mm density keeps internal resistance low while its tensile strength and toughness suit high-speed automated enveloping.

01

Daily deep discharge

Traction batteries are cycled deeply every working day — the hardest duty cycle in lead-acid. Deep-cycle charge and discharge performance is this series’ design center.

02

Dendrite pressure

BET ≥1.6 m²/g binds electrolyte tightly to the fiber matrix, resisting stratification and dendrite penetration through thousands of partial cycles.

03

Low internal resistance

A thin sheet — 0.5–1.2 mm at 100 kPa — keeps internal resistance low, while tensile strength and toughness suit high-speed automated enveloping.
