FIELD: physics.
SUBSTANCE: invention relates to lead-acid accumulators, particularly, to non-woven fibre boards for use in lead-acid batteries. Non-woven fibre bonded plate for lead-acid batteries is provided. Non-woven fibre plate comprises a plurality of fibres coated with a sizing composition, a binding composition and one or more of colloidal silicon oxide and organic active compounds, wherein said organic active compounds are included in one of said gluing composition and said binder composition. Organic active compounds are effective in reducing or preventing sulphation in lead-acid batteries.
EFFECT: invention reduces probability of sulphation in lead-acid batteries.
