Customer ServiceTo recycle silica and use it for fabricating new battery separators, waste polyethylene separators were collected from spent lead-acid batteries. Also, to fabricate new silica-PE separators, ultrahigh molecular weight polyethylene (UHMWPE), GUR 4120, T m = 139 °C, with a density of 0.93 g/cm 3 and molecular weight of 5*10 6 g/mol was provided by Ticona.
Customer ServiceThis study focused on reusing silica from spend lead-acid battery separators by extracting and reusing in new separators with similar properties. However, in extracting stage, silica needed to be washed by dilute nitric acid to eliminate lead oxide impurities. 95% purity of silica was achieved after the washing.
Customer ServiceThe recommended water to acid ratio for a lead-acid battery is generally between 1.2 and 2.4 liters of water per liter of battery capacity. This means that for every liter of battery capacity, there should be between 1.2 and 2.4 liters of electrolyte solution. The most common ratio is 1.5 liters of water per liter of battery capacity. It''s important to note that the
Customer ServiceLead-acid batteries – almost all batteries in fact – comprise an anode, a cathode, a separator, and electrolyte. Separators feature far less in the media than the other three components. So today we ask what role does a lead-acid battery separator play, and how did they evolve.

Customer ServiceLead-acid batteries, invented in 1859 by French physicist Gaston Planté, are the oldest type of rechargeable battery spite having the second lowest energy-to-weight ratio (next to the nickel-iron battery) and a correspondingly low energy-to-volume ratio, their ability to supply high surge currents means that the cells maintain a relatively large power-to-weight ratio.
Customer ServiceAn improved PE separator has been developed by using a PE resin of high molecular weight. The resistance of the separator to attack by hot sulphuric acid is increased by a factor of 1.5. Batteries using the improved separator show a 40% increase in lifetime under the SAE 75 °C life-cycle test.

The surfactant cannot be easily removed or washed away and thereby imparts sustained wettability to the
Customer ServiceThe separator is one of the most critical components of the lead/acid battery. Too often, its role in determining performance and life is ignored. Although its primary function is to prevent electrical contact between plates of opposite polarity, it must also give free movement to sulfate ions through the electrolyte space, but restrict the migration of antimony ions from the

Fan and White chose a α value of 2.5 for separators in NiCd batteries and Doyle et al. used 3.3 for lithium-ion batteries. Arora et al. measured the value as 2.4 for PVdF-based separators by measuring the separator and electrolyte conductivity at different salt concentration.
Pore size – A key requirement of separators for lithium batteries is that their pores be small enough to prevent dendritic lithium penetration through them. Membranes with submicron pore sizes have proven adequate for lithium batteries. 13. Tensile strength – The separator is wound with the electrodes under tension.
Therefore, recycling comes to the field to fulfil these needs. This study focused on reusing silica from spend lead-acid battery separators by extracting and reusing in new separators with similar properties.

Polyvinylchloride (PVC) and polyethylene (PE) separators have been the most commonly used separators in automotive batteries for the last 20 years. Polyethylene separators have a narrow pore-size distribution. The PVC separator is built up by sintering PVC powder in general of a particle size ranging between 10 and 20 μm.
