Drained Lead Acid Battery Scrap

 Drained Lead Acid Battery Scrap

Drained Lead acid batteries scrap are made up of plates, Lead, and Lead oxide with a 35% sulfuric acid and 65% water electrolyte solution. Lead acid batteries represent almost 60% of all batteries sold worldwide.

Classification:

Generally there are two types of Lead-acid storage batteries, based on their method of construction Flooded or Sealed. Flooded (or wet) Lead acid batteries are those where the electrodes / plates are immersed in electrolyte. Sealed Lead acid or valve-regulated Lead acid (VRLA) battery where the electrolyte is immobilized. All Lead-acid batteries produce hydrogen and oxygen gas (gassing) at the electrodes during charging through a process called electrolysis. These gases are allowed to escape a flooded cell, however the sealed cell is constructed so that the gases are contained and recombined.

Lead Acid Battery waste Recycling

The grid structure in both batteries is made from a Lead alloy. A pure Lead grid structure is not strong enough & therefore other metals like antimony, calcium, tin, and selenium in small quantities are alloyed for added strength and improved electrical properties.

The electrolyte in a Lead-acid battery is a dilute solution of sulfuric acid (H2SO4). The negative electrode of a fully charged battery is composed of sponge Lead (Pb) and the positive electrode is composed of Lead dioxide (PbO). The separator is used to electrically isolate the positive and negative electrodes.

 

Waste Batteries

The typical Lead-acid battery comprises of: metal grids, electrode paste, Sulphuric acid, connectors and poles of Lead alloy, and grid separators made up of PVC. The battery components are contained in corrosion and heat-resistant housing usually composed of plastic (polycarbonate, polypropylene, or polystyrene).

Component

[wt.-%]

Lead (alloy) components (grid, poles, ...)

25 - 30

Electrode paste (fine particles of Lead oxide and Lead sulphate)

35 - 45

Sulphuric acid (10 - 20 % H2SO4)

10 - 15

Polypropylene

5 - 8

Other plastics (PVC, PE, etc.)

4 - 7

Table : Composition of Typical Lead-Acid Battery Scrap

In the past, grids were mainly made from antimony-Lead alloys, but new trends show an increase in the usage of calcium-Lead alloys. The electrode paste of used batteries is a mixture of Lead sulphate and Lead oxide. The composition of typical battery scrap material is given in Table.

Drained Lead Acid Battery Scrap

Drained Lead Acid Battery Scrap shall consist of whole drained lead/acid batteries. May contain plastic or rubber cases, but may not contain wooden, metal or glass cases. Similar to ISRI code RAINS.
This is the most preferred type of raw material for Lead recyclers/smelters or recycling/smelting Industries. We provide Rotary based Smelting plants for processing such raw material with equipments & machines for handling & separation of Lead.

4 Best ASIC Miners 2021 1.  Bitmain Antminer S17 Pro Launched in 2019, Bitmain’s Antminer S17 has a hash rate of 56 TH/s. This translates to around 0.0004 BTC mined per day.  The S17 Pro consumes around 2094 – 2568 watts per hour of regular operation. Assuming that the electricity cost is $0.12 KW/h, Bitmain Antminer S17 will give you approximately $13 (at 2500 watts) in daily profits, which calculates to more than $4,500 in yearly returns at the current BTC price. Honestly, these are good numbers; S17 Pro yields positive ROI.  Antimer S17 Pro runs on a second-generation 7 nanometer chip – BM1397, allowing S17 to achieve 56 TH/s. This is a massive increase from S15’s 18-28 TH/s.  As for power consumption, the S17 Pro needs a significant amount of power to cool the device. Nonetheless, it has three operation modes – Low Power, Normal, and Turbo. Furthermore, using S17 Pro’s mode-switching functionality, you can dynamically manage your mining operations. Also, if you k...
