how to safely use the cell phone lithium battery
Internal lithium-ion cell phone lithium battery charge and discharge process in the negative ? positive ? positive state of motion, due to strong activity of lithium itself, so the charge and discharge process may have accumulated in the positive and negative, in the event of accumulation, it will have lithium dendrites (one of the main types of

crystal growth), pierce dendrites may insulation, resulting in micro short circuit, short circuit caused a lot of heat generated inside the battery electrolyte, insulation materials, local gasification, resulting in increased pressure within the battery , and when the pressure increases to a certain degree of strength of the shell will explode when you can not afford.
This shows that the charging of lithium-ion battery will explode, especially lithium-ion battery for more than 5 magnification easily explode. In the small current charge, the reaction rate slower than the combination, accumulation of lithium atoms will not form, so relatively safe. In the formation of lithium atoms over flow faster, thus giving the accumulation of lithium atoms, resulting in short-circuit the battery internal resistance,release a lot of heat, so that a large number of electrolyte decomposition gases, the internal pressure caused a sharp increase in battery explosion.
In addition, the cell phone lithium battery overheating (150 ? or more) will explode.
Because of lithium cobalt oxide and graphite in the sub-atomic state is the existence of conditions in the heating greatly increased its activity in more than 150 ? above greatly reduced the role of lithium, the lithium electrons and lithium nuclei very close, close to or reach lithium atomic state, the lithium atoms can react with the electrolyte, causing the battery to explode.
1. As far as possible use the original charger. Battery both work, materials, safety and other areas in full accordance with international electrical safety standards of manufacturing, the basic battery safety can be guaranteed, while the fake is not only less battery over-current protection device, overcharge protection circuit and temperature sensor, easy to cause an explosion . Although compatible charger can also be used, but some failed because of electrical properties, will damage the battery.
2. Do not place the battery in high temperature under high temperature will cause the battery to increase the heat, then easily explode. Therefore, charge the battery or place the phone with the battery, be sure to choose a place away from heat, but also to avoid direct sunlight during the summer.
Two lithium ion batteries exploding due to overcharging. This isn’t to show that lithium batteries are unsafe. I just got bored and decided to blow up a couple cells from an unused battery I had lying around by removing their circuit protection. Explosions are a lot of fun.

We love machine exactly how lithium battery maintenance is correct? This problem has plagued many people for a long time at the forum there is no uniform opinion. I looked up some information and consulted a friend (who the Department of electrochemical professional doctorate), and the introduction of the Friends under the advice of a well-known domestic battery, deputy director of the Institute. Can not arrogantly have resolved the issue and maintenance of lithium ion, but some of his recently acquired knowledge and experience to write about. The author of the study beyond the high school chemistry chemical Coban Orsay, have since been studying and working in the IT field, ?????, one must understand that even more shallow, N. of salt, but expert Dell inspiron 9400 battery Compaq presario R3000 battery Dell inspiron 1300 Battery.
Lithium-ion battery cathode material of lithium active compounds are usually composed of negative electrode is a special molecular structure of carbon. The common major components of LiCoO2 cathode materials
Negative reaction: C + xLi + + xe-CLix
Battery overall reaction: LiCoO2 + C Li1-xCoO2 + CLix
Discharge, then the occurrence of the above reaction of the reverse reaction.
Charging, the battery added to the positive pole of the electric potential to force the release of compounds Li + ions, embedded negative elements arranged in lamellar structure of the carbon. Discharge, Li + ion from the lamellar structure of carbon in the escape and re-cathode combination of compounds. Li + movement to promote a current. Laptop toshiba PA3399U-2BRS battery maintenance methods – 3, after the exhaustion of electricity charge and avoid charging time is too long regardless of your notebook to use nickel-metal hydride or lithium-electric power, it must take charge after the exhaustion of power (capacity less than 1%), which is The best way to avoid the memory effect. There is no memory effect on lithium to say, I have been in the preceding description is misleading and irresponsible businesses. Lithium-Ion battery memory effect will be the same, but it is the memory effect than nickel-metal hydride smaller Bale. Mobile phone battery charging with the same way, when you charge the battery to the laptop, try to avoid too long, the general control within 12 hours. As for the prevention of exposure to prevent damp to prevent the erosion of chemical liquids, avoid contact with the battery contacts with metal objects such as attention, not much to mention here also.

?1? errors reach 100% charge will be an explosion
As the operational need, urban areas, Mr. Lin has recently tried to buy a laptop computer. However, when he was buying was heard people say that when the laptop is usually in charge can only charge to 99%, can not charge to 100%, if the charge to 100%, then the laptop battery will explode. After hearing this, Mr. Lin hesitated, and in the end this laptop battery Security less secure? Dell Inspiron 8200 battery Dell FK890 battery Dell Inspiron 1721 battery Dell Inspiron 1300 Battery
Industry sources have told reporters on the market of this popular “saying” just a rumor. Because the laptop battery will appear in terms of risk of explosion is very small, only send a maximum of heat caused by melting shell and rarely cause an explosion. The few published laptop battery explosion, mostly due to the battery when in the production of quality problems caused. The reason why laptop battery can not charge to 99% after the then 100%, it is because the battery control circuit of the record and the state of the battery itself has gone wrong, the battery has not reached the voltage Dell Inspiron 1520 Battery Dell Latitude D600 Battery Dell XPS M1330 battery Dell Latitude D531N Battery control circuit in the record, so control circuit has been In the power-up, charging, but in fact the battery is already full, and encountered this problem can be corrected to resolve.
Ugh… power outages. Gotta love waking up to find out you can see your breath misting when you are inside… *warms toes on register* Everything is fine though… Now anyways… onto the video! I am finishing up World 2 today… and as far as recording progress goes, I used my laptop battery during the outage to record World 6, so I am quite ahead of the postings. XD Stage 9: Flowerless Fort – This stage is not really all that difficult… which is to be expected as this is only the second castle. There IS a magikoopa segment… (definitely not a fan of those) …but it is still not all that bad. Just take your time and you should be able to clear it with ease too. Secret Stage 2: Marble Zone – Yeah, you can see where this is going… Just count the stages in the secret world and think back to how many zones there are in the original Sonic the Hedgehog game on the Genesis. The Marble Zone stage is likely the shortest of the bunch… even the secret exit is very easy to find, its only requirement is for you to have at least a mushroom by the time you reach near the end of the stage. I hope you like fire, cause this stage is full of it! You can download this rom hack from: www.smwcentral.net Do NOT ask me where to find the actual Super Mario World rom. I will not tell you where to find it, and persistent asking will get you blocked, understood? Enjoy!~

Explosion of the HP laptop battery
Recently, explosion of the laptop battery is happening often. Pay a high price to buy a problem hp g60 extended battery that have a risk of explosion danger. It is hard to accept for the end-user. But such events, happen again on your site.
On 3.15 CCTV party let HP once again run into Public Relations Crisis. DV2000 and DV3000 Series by exposure exists notebook remains fault. But the bigger problem lies about the consumers in the service of consulting, it is hard to be satisfaction for the consumer with the HP’s reply. HP, Toyota recalled the quality, purchased claim door.This series of hidden behind the quality problem, is the enterprise operation mode of existence of problem? With the product function and product to product quality service, whether the transition should be redefined? In consumer products and services used in the process of consumers and businesses, how is the opposite relationship? How should consumer safeguard their legitimate rights and interests?
Quality problem is the issue today. “We can get to the lowest price products, HP channel components to China has six cities, our telecom operators and the most extensive cooperation…” A year ago, when the HP global vice President, general manager of China HP information products on the Internet group weekly, he must not think today because of the HP laptop quality problem is to push a two-decade-long public opinion. By 2010, March 15 HP’s web site launched a “customer care to enhance plan”, because of its products and services to the customers “inconvenience for” and promised in the computer if customers within the scope affected models, and maintenance, hewlett-packard has board will provide the since the date of service of the two-year extension motherboard again. “Affected” models are mainly concentrated in the hp ev12 / dv6000 and Compaq Presario v3000 / v6000 series, the 2006 laptop computer products in nearly three years, because “flash screen”, “snow screen”, “quality problem such as overheated” mainboard by many complaints, and HP consumer is satisfactory solution to it in China, facing the most massive rights of collective action alliance complaints. Under the press of internet complaint and CCTV, HP China meet the media urgent on 3.16 and have the first public comments about the event. Mr.Zhang said, This incident, HP through a large number of internal investigation is confirmed, the execution of the service policy and HP to question. If you have problems, according to clause 3 HP will promise strictly enforced. On March 20, HP increased “care plan”, covering almost covers HP most low-end products.
Such event, maybe customers are nail-biting. So we should buy the A-class goods and take good care of your laptop battery.
