The Classification of External Battery

According to the different of battery cells, we can divided externalbattery into two species, one is the original lithium batteries, another one is polymer batteries. There are big difference in the material composition and shape between them.

1. Original lithium batteries

The advantage of ordinary lithium cell battery, Because of the relatively long development time, the price of the battery is very low. The disadvantage are, there are many waste refurbished battery, because of the process causes, the problem rate and failure rate are high during producing. Institutional, heavy weight, short life and may cause an explosion. The mainstream mobile power phasing out of such cells. In the coming days, the ordinary lithium batteries will gradually withdraw from the stage of history.

2. Polymer batteries

According to the Electrolyte materials used in lithium-ion battery, lithium ion battery can be divided into liquid lithium-ion battery (abbreviation LIB) and polymer lithium ion battery (abbreviation LIP), the Positive and negative materials used in polymer lithium-ion batteries is the same as used in the liquid lithium-ion battery, Cathode material can be divided into lithium cobalt oxide, lithium manganese oxide, ternary materials and lithium iron phosphate materials, Extremely negative is graphite. The battery’s working Principle also consistent, The main difference between them is the electrolytes different, the liquid lithium ion battery use the liquid electrolyte, and lithium ion polymer batteries use the solid polymer electrolyte instead, Such polymers can be a "solid state", can also be "colloidal state", most of them use the polymer gel electrolyte present.

The detailed introduction of External Battery

External Battery, also called mobile power, mobile battery, backup battery, The concept of “ External Battery “ is development with the popularity of digital products’ rapid growth, its definition is convenient and easy to carry large-capacity portable power supply.

Now, the digital products function is Increasingly diversified, and the use of them is more frequent, it has more and more closely associated with our daily life, the importance of How to increase the use time of the digital products, to play its most important function is even more urgent. ExternalBattery, is the best solution to solve this problem, Carry a mobile power can be achieved mobile charging to a variety of digital products in anywhere outdoor.

Working Principle

External battery is a portable device that a set of electrical storage, boost, charge management, Storage dielectric generally use lithium batteries, because of the relatively small volume of lithium batteries, large capacity, wide market liquidity, affordable, widely used in digital products. The voltage of lithium batteries is between 2.7V – 4.2V, the voltage decreased with the decline in electricity consumption, and Voltage of 2.7-4.2V can not directly charge the other digital products, Because digital products lithium voltage is also 2.7-4.2V, the voltage between the same potential can not be charged. So the output power of the mobile power must have a boost system, boost the 2.7 – 4.2V voltage to 5V, so that it can charge to other digital products, such as cell phone, MP4, tablet pc, psp and so on. Of course, the mobile power is not a one-time equipment, it can be used repeatedly hundreds of times over. So when the mobile power is used up, we must charge the external battery, The principle is the same with charge the cellphone, Connected to 5V USB computer interface or USB charger cancharge mobile power. So the external battery must also have a charge management system, the charge management system can automatically adjusts the charge current based on the voltage of the lithium batteries, the Process have pre-charge, constant voltage charging, and Float charging, etc..

Sony will also enter the Windows Phone market

Sony mobile, the UK and Ireland general manager Pierre Perron in IFA general meeting told reporters: "Sony's strategy is very open, Microsoft has always been our partners. Although android is our preferred partner, but Sony is clearly not only select the single partner. Now we are in talks with Microsoft, hope to make our products more diversified. "

Pierre Perron pointed out that in the upcoming marketing activities, sony will highlight the integration of Sony mobile phones, tablet PCs and TV. Such as achieve the shares of pictures and photos through two devices that support NFC, without the use of Bluetooth or Wi-Fi. This will become a selling point of the Sony Windows Phone 8 and Windows8 equipment.

It seems that sony has a great change in the attitude to Windows Phone, the CEO of Sony Ericsson ever said that “invest money to a platform that is not better than the current system will made ​​me feel uncomfortable, so we will continue to adopt the Android system, although I am curious to Windows Phone.

The restore method of Laptop Battery Loss

Many people often complain that their laptop’s using time is short, or aften using a certain time, the laptop using time get short, this is because of the laptop battery loss, and is there any method that can restore the laptop battery. Now introduce what is the laptop battery loss and how to restore the laptop battery, make the laptop using time get longer.

Laptop Battery Loss

Any battery (including notebooks’) will have a design capacity, such as: 4800mAh, 23Wh, these are the maximum capacity representation, In fact, the actual capacity did not reach so high, or after a certain period of time will become smaller and smaller, such as: the label on the battery is 4800mAh, but actually, only 4500mAh, then this difference between them is battery loss = (4800-4500) / 48,00*100% = 6.25%. There is a variety of reasons can cause the Laptop Battery Loss, so we should avoid the occurrence of the following circumstances as soon as possible:

1. The poor quality of the battery itself, the battery loss increases after using a period of time.

2. The charger is not good, its charging voltage and current can not reach the battery charging requirements.

3. Using the laptop in high or low temperature environment for a long time, also will cause the battery loss increases.

4. Most batteries has remaining power protection, it will start protection after the battery power is less than 3%, but sometimes the users charge the battery after the battery is full discharged, this is not correct.

5. Frequently not fully charge and discharge, the battery did not run out and charge it as they like, which will also caused the battery loss.

6. Not standardized mating battery, or long-term use the battery in the very moist conditions, and long-term use the power in the electromagnetic radiation (leading to a conductive metal in the battery)

The restore method of Laptop Battery Loss

The most common notebook battery loss repair method is charge and discharge notebooks, we can use the external software monitor battery loss. The battery have a certain of loss is normal, new laptop should not use, now introduce how to restore the battery loss through charge and discharge.

The easiest way, Open My Computer - Control Panel - Power Schemes, choose all time parameters using Power Options selected as "never" and "alert" option untick. Unplug the laptop power cord, and stay the laptop to automatically shut down, (in this process, do not let the machine standby); repeated for three times like this, allows notebook greatest degree ofrepairing batteries loss.
