Battery, defined in a narrow sense is itself generally stored chemical energy into electrical energy device, broadly defined as pre-stored energy from the device into external power available. So, like solar conversion without storage function only means not a battery. Other names have batteries, batteries, and Chinese have storage tanks and bottles intended effect.
Historical battery can be traced back two thousand years ago in ancient Iraq era. In the capital Baghdad found unglazed clay pots. It is a copper and iron battery.
Type of Batteries
Chemical batteries, electrochemical cell means by an oxidation-reduction reaction, the positive electrode, a negative electrode active material of chemical energy, into electrical energy for a class of devices. Common redox reaction with different oxidation and reduction reactions that are carried out separately, the oxidation of the negative electrode, the reduction in the positive electrode, and the electron gains and losses is carried out by an external circuit, thus forming a current.
Dry and liquid batteries distinguish battery is limited to that period of early development. The first battery of a glass container filled with an electrolyte and two electrodes. Later we introduced to paste electrolyte-based batteries, also known as dry batteries.
Disposable batteries (Primary Battery), commonly known as "disposable" cell, because after their power runs out, can not be recharged using only discarded. Common disposable batteries include:
Manganese battery - voltage of about 1.5V, the battery capacity is low, the battery can output low, almost alkaline manganese batteries are replaced, except after long-term storage is not leaking harmful corrosive liquids, so still in use in low electricity requires long-term use of devices simultaneously, such as clock, infrared remote control and so on.
Alkaline manganese battery - voltage of about 1.5V, battery capacity and output of the battery than the zinc-manganese batteries is high, but less than nickel-metal hydride battery, after long-term storage of hazardous leaking corrosive liquids.
Other disposable batteries include zinc batteries, zinc-air battery, zinc-mercury batteries, mercury batteries, battery and magnesium hydroxide, manganese batteries.
Rechargeable batteries, also known as the secondary battery (Secondary battery), batteries. Rechargeable battery according to different production materials and workmanship, the advantage can be reused many times after it is charged, they can be full charged and discharged more than two times or even up to 2500, the rechargeable battery output current (load force) than large part disposable batteries is high. Common types are:
Lead-acid battery - voltage of about 12V, low capacity, but can output more power, battery, often used in automobiles for starting the engine to use, or for uninterruptible power system (UPS), radios, communications machine.
