Taiyuan, to enter the peak of the electric car battery scrap
Taiyuan, to enter the peak of the electric car battery scrap
Taiyuan Road, who lives in the building of Mr. Liu more than a year ago bought a fleet of electric bicycle, after a year of use, non-rechargeable laptop batteries into the power has been, and may replace the old battery but I do not know how to deal with him. Yesterday, a press interview on this issue and found that the earlier the purchase of electric bicycle owners shared. Environmentalists who said the city used batteries for electric bikes to replace the peak has occurred, should be a matter of sufficient importance.
According to statistics, currently there are about a variety of city electric bicycle market 120,000, each year tens of thousands of vehicles to the increase in the growth. It is understood that the market for electric bikes is that the vast majority of used lead-acid batteries, only a small part of a lithium dell battery. Lead-acid batteries primarily by lead and sulfuric acid and other metal components, service life is generally 1-2 years. If people can throw away, will not only seriously contaminated soil and water, but also may lead to human neural metabolism, reproductive disorders, etc., will induce serious malignancy.
South Road is located in the building of a store’s sales of electric bikes said: “Customers can take the old battery to us to new ones, of course, need to pay a certain degree of depreciation costs, usually the cheapest 20 ~ 30 yuan. As a vendor, we is for manufacturers to do the recovery work. “in the Sino-Austrian peace Mall Road, the reporter found a lot of electric cars here are committed to recycling the old store batteries, also said that the recovery is for the manufacturers, but when the reporter asked for a recovery is one, the sales staff said: “how could it?” meaning there is still a large number of used batteries from the loss. Sales of Guangdong and another production of the sales of electric vehicles, said: “do not have to use batteries, we collected did not take place.”
An electric car dealer, said, in fact, manufacturers of electric vehicles is the need for lead-acid battery recycling. However, custody and other aspects of transport and the cost of spending more, recycling old batteries is not worthwhile, so the consumer has committed to recycling of old batteries are often not fulfilled. Village workers in purchasing a waste, a middle-aged man told reporters: “electric vehicle batteries 5 cents a pound.” “How the battery can be sold for money?” To “open the battery, draining a ‘water’, which There are copper and, sell all of these things. “” That’s’ Water ‘was wrong? “” on the back in the sewer in, or down the side of the road is required. In any case,’ water ‘has no use. “in man that was very easy.
How to maintain a digital camera battery
DC used today generally have two kinds of battery: lithium battery, and dedicated on the 5th AA batteries (Ni-MH rechargeable battery most commonly used). Lithium-specific light weight, large capacity, environmental protection, and virtually no “memory effect”, but very expensive, poor general, but also a lot of fakes. Ni-MH battery has a high capacity, deep discharge, overcharge and excessive resistance discharge, and shorter charge time obvious advantages. The most important thing is nickel-hydrogen batteries are cheap, high universality.
No matter what kind of batteries, with DC as long as it is sold, the general statement in the Notes will be used, and some manufacturers even print a separate report on the use of batteries and chargers guidelines. Some of these instructions is the most basic but also very necessary road maintenance, such as battery charging method should be chosen, such as charge time. Unfortunately, many users tend to ignore these instructions, shelved. Suggestions: For DC novice, spend some time reading these guidelines, is absolutely necessary.
Ordinary users in the use of DC, the battery often do not have a dedicated storage bag; users to replace the battery after the battery of the habit easily placed, regardless of whether the place where a clean, damp. The consequences of such a battery is easy to stain, easy contact with the metal contacts such as keys, etc., easy to damp, and these are the enemy of batteries. Recommendations: the user should set up a special place at the battery and keep the battery clean. In order to avoid issues such as power loss occurred at the two ends of maintaining contact with the battery and internal battery lid clean and, if necessary, use a soft, clean dry cloth graze.
If DC does not use a long time, the dell 6y270 battery, dell c1295 battery must be removed from the machine and kept in dry, cool environment. This is no disagreement that we are all, but why here also brought up for discussion? Because it relates to another key issue: For the nickel-metal hydride batteries, the battery should be fully discharged and then save, save, or live? These two very different views of what it should be used? Many people think that we should adopt the former, but I think a more reasonable to preserve the battery charged. Because: According to tests, Ni-MH battery to preserve the best condition that saved about 80% charged. This is because the nickel-metal hydride battery greater self-discharge (10% -15% a month or so), if the battery fully discharge and then preserved a long time not to use, the battery will result in the phenomenon of self-discharge the battery over-discharge, will damage the battery. Do not believe? What do you think about buying a new nickel-metal hydride rechargeable batteries is not all there is electricity, which is the reason. Recommendations: more than compared to correct the wrong point of view, from the right direction to start maintenance batteries, or else they will backfire.
Japan’s flexible solar cells a substantial increase in power
Researchers in Japan through technical improvements, the success of the flexible type of dye-sensitized solar cells a substantial increase in power, each 12 square centimeters can be the output of the battery plate voltage above 4 V, is expected to be used to provide power, such as outdoor advertising.
According to “Nikkei Sangyo Shimbun” reported that dye-sensitized solar cell-based film material in the pigment and power generation components used for power generation, and compared to silicon solar cells, and its advantages can be bent, using the printing technology, which costs relatively low . However, before such a flexible battery, even in strong sunlight, each 12 square centimeters of voltage they can only produce 0.7 volts.
Improved type dye-sensitized photoelectric conversion efficiency of solar cells up to 4 ~ 5%, is a standard silicon solar cells of 1 / 3. Maximum power of 0.4 watts, test products will be linked to the three modules, voltage up to 12 volts or more. Typically, the voltage above 10 V can be used for storage of electrical appliances and rechargeable lithium batteries, the average cell phone charge 4 hours to complete.
Flexible solar cells that, if the practical application of inputs for outdoor advertising, laptop computers-dell inspiron 500m battery, dell inspiron 510m battery, cell phones and home appliances, such as the provision of power supply products.
