Depth analysis of laptop battery

Notebook how long the first charge is appropriate, the explanation must be in business more than 10 hours to ensure the laptop battery is fully activated. Although we are very careful to use our laptop batteries, but the books of the standby time is less and less. So how laptop battery charging is the most appropriate?

I give you a brief introduction:
Depth analysis of laptop battery materials
Lithium-ion battery cathode materials are usually composed of active compounds of lithium, the negative is a special molecular structure of carbon. Common cathode materials mainly composed of LiCoO2, charging, added to the Canon Bp-511 Battery positive pole of the electric potential of compounds to force release of lithium ions, embedded negative elements arranged in lamellar structure of carbon. Discharge, the lithium ion from the lamellar structure of the carbon in precipitation, re-cathode combination of compounds. Lithium-ion movement generates a current.
Although the principle is very simple chemical reaction, but in the actual industrial production, the practical problems need to be considered much more: the cathode material additives needed to maintain the activity of multiple charge-discharge, cathode materials needed to design the molecular structure level accommodate more lithium ions; fill in the electrolyte between the positive and negative, in addition to stability, but also has good electrical conductivity, reducing the HP Compaq Mobile Workstation nw9440 Laptop AC Adapter battery's internal resistance.
Although lithium-ion battery with little memory effect of nickel-cadmium batteries, memory effect is the principle of crystallization in lithium battery is almost no reaction. However, lithium-ion battery capacity after repeated charge-discharge will continue to decline, its causes are complex and varied. Mainly positive and negative changes in the material itself, from the molecular level, the positive and negative ion on the hole to accommodate the structure will gradually collapse, clogging; from the chemical point of view, is the active anode material is passive, there's another side to form a stable compounds. Physical cathode material will appear on the gradual falling off, etc., in short, ultimately reducing the Compaq 354126-001 Battery  will be free to move in the charge-discharge process of lithium-ion number.
Overcharge and over discharge, lithium-ion battery anode cause permanent damage, from the molecular level, intuitive understanding, excessive discharge of carbon anode will lead to excessive release of lithium ion and makes its lamellar structure collapse, excessive Rechargeable lithium-ion will too hard to go into the negative carbon structure, while making some of the lithium-ion no longer be released. This is the lithium-ion HP Pavilion dv6-1100 Laptop AC Adapter batteries are usually equipped with charge and discharge control circuit causes.
Not suitable for the temperature, the internal lithium-ion battery will lead to other chemical reaction of the compounds we do not want to see, so many of the lithium ion battery between the positive and negative temperature with protective membrane or electrolyte additives. To a certain temperature in the battery case, the composite membrane electrolyte membrane hole closed or degeneration, the battery internal resistance increases until the circuit, the battery is no longer warming, to ensure that the Dell 1691P Battery charging temperature is normal.
And deep charge and discharge lithium-ion batteries can improve the actual capacity? Experts clearly told me that this is meaningless. They even said that the so-called three full charge and discharge before using the "active" in their knowledge of two doctoral years, could not understand what this is necessary. Why do so many people, however, after the deep charge-discharge capacity Battery Information in the label will change it? Will be mentioned later.
Notebook computer lithium-ion Panasonic Nv-gs27 Battery are generally charged with the management chip and control chip. Which management chip in a series of registers, there is capacity, temperature, ID, charge status, discharge frequency values. These values ​​are in use will gradually change. Personally, I think, for use in notebook computers in "one month after the full charge and discharge should be a" major role in the practice is to fix these registers should be in the wrong value, making the battery charge control and battery nominal capacity consistent the actual situation.
The main control chip charge control the battery charging process. Lithium-ion battery charging process is divided into two phases, constant current fast charge phase (HP Pavilion dv6-1100 Laptop AC Adapter  battery indicator light yellow) and the constant current phase (the battery indicator light flashes green. Constant current fast charge phase, the battery voltage gradually rises to the standard battery voltage, then under the control chip into the constant voltage phase, voltage will not rise in order to ensure that no over-charging, the battery current is increased gradually with the decrease to 0, and the final charge.
Statistics chip power consumption by recording the discharge curve (voltage, current, time) can calculate the sample battery, this is what we read in the Battery Information in the wh. Value. The lithium-ion batteries after repeated use, the discharge curve will change, if the chip has been no opportunity to read a complete discharge curve, the calculated power is not accurate. So we need to calibrate the Samsung es70 Battery charge-discharge deep chips.
