Laptop Battery KnowledgeâBattery History
We can’t live without batteries in our everyday life.when your open your laptop to work or play games,you have to make sure the Battery works order.another day it’s would drive you crazy if you can’t use your laptop,only because there were something wrong with the laptop battery.so.the batteries are very importent to everybody.but how much you know about the battery?do you just know little about history of them.today.i will talk about this.
Due to its universal applicability, electrical power plays a central role in the technology which surrounds us. The “disadvantage”: Electricity must be consumed by the way. It cannot be stored or created by simple devices; it must be obtained directly from a power station. The quantities of electrical energy which can be stored directly, e.g. in capacitors, are so small that they can only be used in units with very low power requirement to bridge interruptions in supply. Therefore electrical energy must be converted into other forms of energy if it is to be stored.
The history of the development of electrochemical cells is crucial to the scientific study and industrial applications of electricity, for prior to the rise of electrical grids around the end of the 19th century, they were the main source of electricity. Successive improvements in battery technology permitted the rise of major electrical advances, from early scientific study to the rise of telegraphs and portable electronics.
In 1749, Benjamin Franklin first used the term “battery” (Dell xps m1530 Battery)to described a set of linked capacitors he used for his experiments with electricity. These capacitors were panels of glass coated with metal on each surface.These capacitors were charged with a static generator and discharged by touching metal to their electrode. Linking them together in a “battery” gave a stronger discharge.
The following is thetimeline of battery history
1748 – Benjamin Franklin first coined the term “battery” to describe an array of charged glass plates.
1780 to 1786 – Luigi Galvani demonstrated what we now understand to be the electrical basis of nerve impulses and provided the cornerstone of research for later inventors like Volta.
1800 – Alessandro Volta invented the voltaic pile and discovered the first practical method of generating electricity. Constructed of alternating discs of zinc and copper with pieces of cardboard soaked in brine between the metals, the voltic pile produced electrical current. The metallic conducting arc was used to carry the electricity over a greater distance. Alessandro Volta’s voltaic pile was the first “wet cell battery” that produced a reliable, steady current of electricity.Â
1836 – Englishman, John F. Daniel invented the Daniel Cell that used two electrolytes: copper sulfate and zinc sulfate. The Daniel Cell was somewhat safer and less corrosive then the Volta cell.Â
1839 – William Robert Grove developed the first fuel cell, which produced electrical by combining hydrogen and oxygen.
1839 to 1842 – Inventors created improvements to batteries that used liquid electrodes to produce electricity. Bunsen (1842) and Grove (1839) invented the most successful.
1859 – French inventor, Gaston Plante developed the first practical storage lead-acid battery that could be recharged (secondary Dell Inspiron 2650 Battery). This type of battery is primarily used in cars today.
1866 – French engineer, Georges Leclanche patented the carbon-zinc wet cell battery called the Leclanche cell. According to The History of Batteries: “George Leclanche’s original cell was assembled in a porous pot. The positive electrode consisted of crushed manganese dioxide with a little carbon mixed in. The negative pole was a zinc rod. The cathode was packed into the pot, and a carbon rod was inserted to act as a currency collector. The anode or zinc rod and the pot were then immersed in an ammonium chloride solution. The liquid acted as the electrolyte, readily seeping through the porous cup and making contact with the cathode material. The liquid acted as the electrolyte, readily seeping through the porous cup and making contact with the cathode material.”
1868 – Twenty thousand of Georges Leclanche’s cells were now being used with telegraph equipment.

1881 – J.A. Thiebaut patented the first battery(Dell inspiron 8600 Battery) with both the negative electrode and porous pot placed in a zinc cup.Â
1881 – Carl Gassner invented the first commercially successful dry cell battery (zinc-carbon cell).
1899 – Waldmar Jungner invented the first nickel-cadmium rechargeable battery.
1901 – Thomas Alva Edison invented the alkaline storage battery.
1949 – Lew Urry invented the small alkaline battery.
1954 – Gerald Pearson, Calvin Fuller and Daryl Chapin invented the first solar battery.
