New Battery Choice

With the use of mercury-containing button battery volume and the increasing volume of waste, waste batteries, mercury pollution of the environment have long been prey to human life. China has independently developed by mercury free button IBM ThinkPad R40 battery patent, has passed the edge of life and death are in the 8th grade.

 

The patent was twice the national commission to review patents declared invalid. Court of Beijing Municipal Higher People’s appellate decision reversing the final two review committee of the patent. In September 2009, the Committee for reconsideration of patent has announced third of mercury-free button battery patent is invalid, the patent owner of the Third Committee of patent examination through the courts. The case is currently pending under the Municipal Court of Beijing No. 1 Intermediate People.

 

The patented technology is no longer a secret at all

 

Why was there for mercury free button 6Y270 batteries have been repeatedly declared the patent invalid, the reporter interviewed a number of contacts of the National Committee of patent examination and in accordance with the requirements of the other one fax overview of the interview, but last Friday the review of patent maintenance staff comfortable and refused to talk with reporters.

 

According to reports, in accordance with our rules of patent protection, patent protection is a patented invention, the disclosure of patented technology for the premise that the inventor in patent applications at the same time, to declare his own secrets patented technology released. That is, if the patent is declared invalid, the inventor is not a secret at all, other manufacturers can not put any development funds for free public use of the technology of others rather than held accountable under the law does not take responsibility.

 

10-year patent protection period expires

 

Mercury-free button on the advice of the Dell Inspiron 5150 battery patent license after a new series of battery companies and individuals have begun to review patent Council to submit an application to declare the patent invalid mercury-free button batteries.

 

May 31, 2004, the National Review of patents by companies both batteries apply to mercury free button batteries are not creative, and said the entire patent is invalid. Guangdong Enterprises to court Leader, December 20, 2005, the Municipal Court of Beijing Higher People’s Committee Final Appeal Decision loses patent review, the court concluded that mercury free button batteries all valid patents.

 

June 19, 2009, the State Committee of patent review a decision for the third time, mercury free button batteries are not creative, and said all the patent is invalid. In October 2009, Guangdong New Leaders of the Third Committee of patent examination to trial, asked the court to revoke the decision of no review committee and the patent void. Currently, mercury free button batteries 10 years patent protection period is about to expire, the ultimate fate of the concern of the patent.

 

“Judicial finality” Why is it difficult to aim?

 

An interview with experts in intellectual property. Experts in the field, the original court in Beijing, a tribunal of senior judges to know Middle Guang Liang Zhang told reporters at the WTO, the case involves a patent license utility model and maintenance procedures, that “the administrative end, the National Patent Review Board makes its decision direct force VGP-BPS9 of law, the parties have no right to initiate an administrative procedure.

 

According to international standards, China “Patent Law” was amended accordingly, and the change of purpose Executive “for” judicial finality “that is made by the administrative department of intellectual property satisfied with the decision, Parties have the right to bring an administrative lawsuit. The final decision by the court.

 

Then, the objective “legal” Why is it difficult to aim? In this regard, Guang-Liang Zhang said that the cycle of litigation to patent litigation, the question, “Patent Law”, the experts, when it is high, but because of the final amendment of the law make no explicit provision leads to a continuation patent is conclusive case 3. Mr. Zhang, that under such circumstances, how to protect the rights of the patented invention is BATCL50L indeed worth exploring.

1, see capacity. Ordinary nickel-cadmium battery 500mAh or 600mAh Ni-MH batteries, but 800-900mAh, while the capacity of lithium batteries for mobile ions are usually between 1300-1400mAh, if VGP-BPS10 battery lithium-ion fully charged before use of time is on the Ni-MH battery 1.5 times that of nickel-cadmium battery 3.0 times. If you find that you have purchased blocks of a lithium-ion cell phone batteries to work on time and does not promote or instructions on the required length, it may be a forgery.

 

2, see the surface of plastics. Battery brand wear uniform surface, using PC hardware, no embrittlement phenomenon; counterfeit batteries without wear or rough, using a renewable resource, easy to embrittlement. 3, see the appearance. All mobile phone batteries real appearance must be clean, flawless additional to some extent on the roughness of the outer surface and feel the inner surface of the touch is smooth, delicate lighting to see the scratches longitudinal. Cell Phone electrode film of the battery and the width of the same corresponding position in the bottom electrode of the battery marked [+],[-] brand of HSTNN-LB31 battery isolation materials, electrode materials and shell as well as, but not one.

 

4, to see symbol. For the original battery, texture of the surface of the battery light colored, uniform, clean, no scratches and obvious damage, the battery label should be printed on the battery model, type, capacity nominal standard voltage, the positive and negative signs, the name of the plant. To be smooth when you touch the phone non-blocking, hair elastic appropriate in hand with a good lock and reliable sheet metal stripes obvious, black and green phenomenon. If we buy mobile phone FK890 battery and the above phenomenon is not consistent, and can first conclude that are false.

 

5, see color. Currently, many manufacturers of mobile phones from its own point of view, efforts to improve the level of technology to increase the difficulty of mobile phone accessories and false to stop the proliferation of the phenomenon of false parallel. General Meeting of mobile phone products and accessories needed to be consistent in appearance. So we bought a cell phone if the battery installed, you should carefully consider the regulatory body and the background color of the battery shell, if the color and brightness consistency original batteries. Otherwise, the battery itself is dull dull, it is a counterfeit FRU 92P1141 battery.

 

6, see the guards. Observed anomalies load. General genuine mobile phone batteries should be over-protective device during the procedure, such as lead in the external load short-circuit is excessive, the threshold for automatic deactivation of the circuit, to avoid not burn or damage to mobile phones, lithium-ion batteries have also over-current protection circuit, when using non-standard electrical appliances, AC power is switched off automatically when too much power, can be recharged in the lead, under normal circumstances, the battery can automatically return to the state of conduction. If we are loading process, found that the 371785-001 battery of severe heat, or smoke, or even an explosion, indicating that the battery is definitely false.

 

7, see Security. A careful examination of fight against trademark counterfeiting. Example stickers hidden under the ramp printed word Nokia is a tip. Flawless is a product of clear and original; dark pale counterfeit Chu Pin. If you look carefully, it may find the name of the manufacturer. For example, batteries for Motorola and its anti-counterfeiting trademarks are diamond shaped, and if at any point of view, may be flashing a three-dimensional effects, while Motorola, and the origin of ‘printing and clear, then it is authentic. Instead, once the color black, three-dimensional feeling inadequate, vague words, it may be false.

 

8, the measured voltage. Measuring battery charging voltage block. If you use Ni-Cd, Ni-MH battery pack counterfeit lithium-ion mobile phone battery pack, it must be composed of five individual cells, a single voltage battery charge is usually not more than 1.55V, the voltage battery does not exceed the total block of 7.75V. Block the load when the battery voltage drops below 8.0V, when there may be nickel-cadmium, batteries nickel hydrogen.

First, battery failure mode of several

 

1. Dehydration

In the process of battery charging, electrolysis of water, producing oxygen and hydrogen to make water into hydrogen and oxygen in the form of loss, and also known as condensate. Water in the system of electrochemical cells, play an important role in reducing the water will reduce the activity of ions involved in reactions, resulting in increased resistance of the internal IBM ThinkPad R52 battery, the polarization intensified, ultimately a decrease in battery capacity.

 

2. Sulfate

The discharge of the battery, the cathode has produced in the lead sulfate cathode, anodic oxidation of oxygen due to the very presence of sulfuric acid is extremely easy for the loading of lead dioxide, lead, while the cathode is different, except in long-term loss of power, often excessive discharge, requiring long-term unless there are other factors will be gradually formed on the surface layer of negative density hard layer of lead sulfate, not only in itself a significant decrease in solubility, it is difficult to participate in the response, while blocking the active electrolyte contacts and deep canal, causing the battery capacity will decrease.

 

3. Plate softening

Plate is a multi-gap material, there area than the plate itself, the more surface area, the Dell Inspiron 1300 battery charge-discharge cycle repeated, with the board very alternative materials processing different rates will gradually plate space decline in performance over appearance, he plate is positive when the surface of a solid from the beginning a gradual change until it becomes very soft, then decreased due to surface would result in a decrease in battery capacity. High-current charge-discharge, excessive discharge would accelerate the softening of the plate.

 

4. Grid corrosion

Skeleton of the battery grid alloy of lead, although there is strong resistance to corrosion, but the long-term immersion in an acid electrolyte, which is still cause corrosion of metals occurred in so that the grid crack or fracture occurs, leading to capacity decline.

 

5. Short

Initially, the diaphragm must be positive and negative plate (plate) separated, but if there are slag welding penetration or dendrites, then the positive and negative plate connected to form a short circuit, a serious short – circuit could cause the voltage becomes zero only if it leads to positive and negative resistance associated with the material itself is great, as the dendrites, it will not immediately single F4486B cell voltage becomes zero, but between autonomy faster discharge, commonly called “soft short-circuit.

 

6. Circuit

Occurs on the bus pole soldering and welding and soldering of the terminal event is usually not completely open circuit, but rather attached to cold welding, when the cold solder joint Department will have a strong resistance, causing decrease in battery capacity. The battery in May to provide a normal startup of all material respects, in use for some time after the cold welding phenomenon material, it is usually due to welding is not a good weld, there are cracks on the use of the process, this region has a first edge corrosion, resulting in a faster rate of fracture increased.

 

7. Thermal runaway

 

Second, Battery Repair

We usually refer to the repair or maintenance, is against the above failure modes of loss of water and sulphate, in fact, there are only two kinds of failure modes that can be repaired, while the rest of the physical damage, but we can not repair. To mitigate the plate, in theory, there is the possibility of repair, but its high cost, the effect of small, so that can only remain theoretical.

 

Third, Repair Method

Water loss from the VGP-BPS9 battery, because the decline of the dissolution of lead sulfate, so the possibility of loss of sulfation increased battery water and thus often can not play an effective recovery simple should be at the same time for the hardening treatment.

To meet basic sulphate battery, we must reduce the density of the electrolyte to improve the solubility of lead sulphate.

From the above analysis we can see that in fact, will address the loss of water must be vulcanized to vulcanization need to add water, and water loss and the elimination of sulphate must be in the same time, specific methods are:

 

1, in the use of the pot, add water-rich liquid, the temperature of the plasma battery repair instrument repair.

Repair Repair of instruments actually contain two principles, one near the lead sulfate on the resonant frequency of the source plasma resonance, so that a layer of lead sulfate drive strength will decrease more easily dissolved, which can be regarded as repair material, and secondly, to rely on the fixed magnetic field high electric potential, so it is not easy to restore the lead sulfate is reduced, which may be regarded as the repair of electrochemistry. This method is a result of both physical and repair of electrochemical double, so it became the most battery-repair market, we recognized and widely used approach.

2, in the use of pot by adding water-rich liquid, using the constant current overload

In this way, only the electrochemical repair functions. Its existence must have its advantages, but there is no sense instrument.
