Energising the battery sector

Precision short cut fibres designed to improve performance and longevity of batteries.

Battery fibres are widely used by battery manufacturers to create stronger and more hard-wearing batteries.

For example, polyester battery fibre is often added to ‘pasted plate’ type lead acid batteries to help with reinforcement and to offer protection from wear and tear.

Polyester and polypropylene battery fibres are extremely useful for reinforcing batteries as the fibres are resistant to chemical solvents, bases, and high strength acids. This means that they are less likely to be dissolved by acid or general use over time, making your battery product superior to those which break down quickly.

RIGOROUSLY TESTED FOR THE BEST RESULTS

Tests which involve vigorous vibration of the plates mimicking general use, normal road conditions, and potential impacts have shown that cut fibre-reinforced batteries last much longer than others.

In fact, plates without fibre were shown to lose an average of 35% of their active material, whereas plates reinforced with Goonvean Fibres’ standard polymeric fibres lost less than 1%.

Technical Details

Polyester is an extremely strong, resilient, and stable man made fibre that is commonly used in a wide variety of industries. It is popular with battery manufacturers because it doesn’t stretch or shrink and it is very resistant to abrasion and acid degradation.

Sizes: 2.10 decitex

Polyester has a relatively high specific gravity, meaning that it disperses very well in water, and a relatively high melting point, meaning that it is heat resistant.

Sizes: 3.30 decitex

Polypropylene (PP) is a thermoplastic polymer used in a wide variety of applications including packaging, textiles and automotive components.  It is rugged and unusually resistant to many chemical solvents, bases, and acids making it an ideal material for use in lead acid batteries.

Sizes: 3.30 decitex

Some applications require a more technical and higher-grade fibre. One example of this is batteries with high DCA demands and harsh thermal conditions that are often used in military, electric vehicle, and aerospace sectors.

This type of battery has been developed for use in hybrid, plug-in hybrid, fuel cell, and electric vehicles and requires a short cut fibre that is resilient and resistant to harsh conditions including acid and high temperature.

Our technical fibres include

Thermafloc+ is an excellent choice for those who want high thermal stability and low shrinkage.
It is able to increase thermal stability by 28% and reduce shrinkage by 82% when compared to standard polymeric fibres.

Sizes: 2.10 decitex

Primafloc+ has been shown to improve and reverse the negative effect caused by the inert polymer fibre, a limiting factor in dosage rates.  It is also able to reduce water loss by up to 50% over 21 days when compared to a typical polymeric fibre.

Sizes: 3.3 decitex

Short cut GVFloc+L has shown very positive results in improving the stability of the electrodes within a lithium ion battery, thus improving the batteries ability to harness the high energy density potential.
