New Battery Exactly When to Change the World

Often focus on tech news, we almost every period of time can see similar "so-and-so new technology/material, it can improve the hp HSTNN-DB06 Battery capacity X times" reported that this new type of battery what time can into our life, but unknown. Suffer from HTC magic less than a day of endurance, laptop battery a serious recession, use the time only ten minutes, so take time to look at the battery information, dearth of legends of the NB winky battery or alternative technology.

Battery brief:
Battery, old and narrow definition is itself stored chemical energy into electrical energy, a new and general definition refers to mechanical energy into electrical energy outside of the energy of the device. (via wikipedia)
The battery can be traced back to the earliest history of two thousand years ago Baghdad, in gallipot inside plug copper, iron, according to speculation may be used to save electrostatic. The modern sense of the battery, the first is the calendar mountain trow's · volts invention production, called voltaic pile.
Simply pick a few historical time point: in 1860, she Thai invention battery. In 1887, helle's invention dry cell. In 1899, Joan Kruger invention nickel cadmium battery. In 1914, Thomas Edison alkaline battery and lithium battery. In 1954, the advent of solar cells. From different angles can be divided into various categories to battery, specific view, baidu wikipedia encyclopedia.
Lithium battery:
Lithium hp Pavilion DV7 series Battery is a kind of the lithium metal or alloy anode materials for lithium, use a water electrolyte solution of the battery. (via wikipedia) lithium is alkali metal, easy polarization other molecules or ions, and itself is not easy polarization, so, the compound poor stability. Therefore, by Edison's invention, to 1970 years to to practical. By 1991, SONY development first commercial lithium ion battery make it into the popular products to. Use lithium compound as anode of the battery has the very high energy density, temperature to adapt to a wide range (according to the difference of the material, can be in - and ° C ~ sixty ° C between normal work).
We usually say that the lithium battery is lithium ion battery and lithium ion polymer battery, can repeat charging.
The lithium ion battery of the advantages:
High energy density (recall the phone, cell accounted for most of the part, and conversation time only poor 30 minutes)
Open circuit voltage high (3.3 ~ 4.2 V)
Output power
No power memory effect (nickel batteries in order to ensure the best performance, every time must be fully charge and discharge, can appear otherwise crystallization, lead to later can't filled with electric)
Low self-discharge
Wide operating temperature range (- and ° C ~ sixty ° C)
Imitation, discharge speed (general electronic equipment 2-4 hours)
Disadvantages:
Easy aging
High efficiency (1%).
Not resistant to overcharge, discharge.
Need multiple protection mechanism. (so that we do now sell lithium battery is undoubtedly bomb)
New battery why can not lift a covering
In the current technical condition, lithium hp 484170-001 Battery capacity reached almost theory limit. The stronghold of the mobile phone so-called super capacity is just increase the cell size and false.
The father of lithium battery - west beautiful mood says improving lithium battery energy density have two kinds of methods, one is to reduce the battery for electric power produces no contribution to the materials; The second is to increase electrode active material of unit weight or unit capacity. The former exists limit, the latter have been looking for. Believe that they do more than ordinary consumers to "Change everything again". No out means is not enough mature, safe enough or too expensive.
There are may replace lithium battery solutions are:
Silver-zinc battery
Ordinary silver-zinc battery is very common, button cell most is that it. But rechargeable, large capacity of silver-zinc battery is too expensive, who can bear the battery than machine expensive? !
Fuel cell
"The Fuel Cell, just as its name implies is driven by Fuel battery. As early as in 1839, the British W.G rove has put forward the hydrogen and oxygen reaction can power generation principle, this is the first hydrogen - oxygen Fuel Cell (Fuel Cell). Usually Fuel produced by the heat energy is released, and Fuel Cell don't release heat energy, it is to break them down into hydrogen ion and electron and converted into electrical energy.
The advantage is no pollution, high efficiency, wide applicable. Disadvantages in big volume and high cost.
Zinc air battery
"Using activated carbon adsorption the oxygen in air or pure oxygen as A positive active material to zinc for negative, with ammonium chloride or caustic solution for electrolytic A galvanic cell. Also called zinc oxygen battery. Divided into neutral and alkaline two system of zinc air hp HSTNN-LB73 Battery, respectively for the letters A and P said, followed by digital indicates that the battery model." defect is short life, including mercury is high, the high cost of recovery.
In fact, the most those who make a person enchanted is this: keep the cell phone in five thousand, all need not charging the r&d super nuclear battery quite ye ah, five thousand years later, a grandson can bottom spirit very said, my family the battery has a history of 5000 years.
