Health care, emphasis on lead-acid battery recycling

 Toxic and hazardous substances accounted for the majority of the composition of the lead-acid battery electrolyte sulfuric acid accounted for 16 percent of leaded substances accounted for more than 70% of these two substances on human health great harm.
It is reported that the total production of lead-acid batteries in China, in 2006 approximately 72,414,000 KVAh, after the past few years an increasing trend. Into circulation of lead-acid pt434 batteries from the production, use, waste link, the hazards to humans and the environment will inevitably increase.

It is understood that a lead-acid batteries can be sold for 100 yuan, no one will lose, and are sold directly to small traders, most lead-acid batteries "outcome" is that the individual sold to small traders, small traders and then these waste lead-acid batteries sold to small smelter.

Lead-acid batteries have done great harm to humans and the environment, the face of the current lead-acid battery market recovery, the relevant departments should take measures to deal with recycling latitude d520 battery issues.

First, the relevant departments should rationalize the lead-acid battery recycling mechanism, the establishment of the lead recycling qualification examination system. The face of the relevant departments of the small traders in the recycling chain should be the introduction of recovery mechanisms and the quality audit system be investigated and dealt with the recycling chain improper prohibited waste battery recycling.

Second, focus on the development of recycling industry backbone enterprises. Meet the qualification requirements of the enterprise to the public directory, a virtuous circle. Recycling business, to build a strong strength of strong strength of the recovery of well-known enterprises, and eliminate consumer waste  studio 1735 battery bought for small traders.

Finally, the relevant departments of propaganda work, so that consumers understand the environmental hazards of waste lead-acid batteries, and consciously with a good lead-acid battery recycling.

How to Test the Battery Power ?

Detect ordinary zinc-manganese dry battery level is sufficient, there are usually two ways.The first method is by measuring the battery instantaneous short-circuit current to estimate the internal resistance of the battery, and then judge the adequacy of battery power; The second method is an appropriate resistance resistor in series with ammeter, calculate the battery by measuring the  Inspiron 1545 battery discharge current resistance, in order to determine whether the battery is sufficient.

The biggest advantage of the first method is simple, with a multimeter the current file can directly determine the dry battery power, the drawback is that the test current, far more than dry batteries to allow the discharge current limit, to a certain extent the impact of dry vgp-bps13 batteries. life expectancy. The second method has the advantage of small test current, security, and generally do not have a negative impact on the life of dry batteries, the drawback is a bit trickier.

I use the MF47 multimeter to a new No. 2 batteries and an old dry cell using the above two methods to test contrast. Assume that ro is a dry  hp g70 battery internal resistance, RO ammeter internal resistance, the second test method, the RF is the additional series resistance, the resistance of 3 ohms, the power of 2W.

The measured results are as follows. New on the 2nd  hp g62 battery E = 1.58V 2.5V DC voltage profile measurements, the voltmeter internal resistance of 50k ohms, is much larger than the ro, it can be approximated to that 1.58V is the emf of the battery, or open-circuit voltage. The first method, the multimeter set 5A DC current file, meter internal resistance RO = 0.06 Ohm, the measured current of 3.3A. Ro + RO = 1.58V ÷ 3.3A ≈ 0.48 Ohm, ro = 0.48-0.06 = 0.42 ohm. The second method, the measured current of 0.395A, the RF + ro, + RO = 1.58V ÷ 0.395A = 4 ohms, current 500mA file internal resistance of 0.6 ohms, so ro = 4-3-0.6 = 0.4 ohms.

Old on the 2nd  latitude e4200 battery when the first method measurements, first measured the open circuit voltage E = 1.2V, the meter internal resistance RO = 6 ohms, a reading of 6.5 mA, a multimeter set to 50mA DC current file, ro + RO = 1.2V ÷ .0065 A ≈ 184.6 ohms, ro = 184.6-6 = 178.6 ohms. The second method, the measured current is 6.3 mA, ro + RO + the RF = 1.2V ÷ 0.0063A = 190.5 ohms, ro = 190.5-6-3 = 181.5 ohms.

Obviously the two results of the test method is basically the same. The final calculation of small differences due to reading error, resistance caused by the RF error and the contact resistance and other factors, this small error would not affect the judgment of the  latitude e5400 battery power. If the measured battery capacity, high voltage, you should adapt to increase the resistance of the RF.

The Photovoltaic Battery Industry

Photovoltaic boom in low-end of, but is also seen as a time when technology research and development, the practice of the golden age of technology the focus of concern in recent cross-strait industry, that is almost a year many international equipment industry continue plans to introduce metal back passivationlayer (backside to passivation) techniques and equipment, the technology in addition to the module side can inherit the current welding technology, efficiency, increase the Inspiron 1545 battery space is expected to reach 0.2 to 0.5 percentage points, however, the equipment industry in the production yield and cost optimization of client considerationsnot impatient launched.

Photovoltaic although a time when the economy low, however,it is the technical sophistication of the active period, the solar industry reports that the moment is to create the golden age of vgp-bps13 technology, competitive differentiation, prepared by the various industry is the battle of the next boom reversed effective use of differentiation to throw off other competitors.

Recent equipment market actively unite the launch of the new technology, that is, the metal back of the passivation layer (backside to passivation), the solar industry explained, the technology is the the AL2O3 film as a P-type solar photovoltaic cells on the back of the passive film or the N-type battery electronic and electrical safety to reach the front, the main purpose is to let the sun in the Inspiron E1505 battery circuit, and not like other technologies like both combined with out the reach and therefore the circuit is blocked, which will make the cell conversion efficiency and thus enhance the This article from the new portal of solar photovoltaic.

The solar industry on simple solar photovoltaic cells, the basic process (base line) point of view, the laboratory, a single increase in the metal back of the passivation layer, you can make the battery is 0.2 to 0.5 conversion efficiency percent, said the solar industry, important that the back-end heritage present a large number of modules and welding technology, no need to make any changes, this is one of the reasons to attract the two sides of Casio NP-20 industry, of course, the Taiwan-based plant-based battery OEM more heart.

However, the import of the technology is expected to increase three to five production station, the consideration of mass production yield is one of the key, so equipment manufacturers to enhance the Fujifilm NP-100 technology and equipment coupled with the technology research and development of the solar plant will affect the success or failure, which is the cross-strait solar plant concerned about one of the major equipment manufacturers launch devices.
