An electric battery is a device consisting of two or more electrochemical cells that convert stored chemical energy into electrical energy. Each cell has a positive terminal, or cathode, and a negative terminal, or anode. The terminal marked positive is at a higher electrical potential energy than is the terminal marked negative. The terminal marked positive is the source of electrons that when connected to an external circuit will flow and deliver energy to an external device. When a battery is connected to an external circuit, Electrolytes are able to move as ions within, allowing the chemical reactions to be completed at the separate terminals and so deliver energy to the external circuit. It is the movement of those ions within the battery which allows current to flow out of the battery to perform work.[1] Although the term battery technically means a device with multiple cells, single cells are also popularly called batteries.

Primary (single-use or "disposable") batteries are used once and discarded; the electrode materials are irreversibly changed during discharge. Common examples are the alkaline battery used for flashlights and a multitude of portable devices. Secondary (rechargeable batteries) can be discharged and recharged multiple times; the original comPOSTTTION of the electrodes can be restored by reverse current. Examples include the lead-acid batteries used in vehicles and lithium-ion batteries used for portable electronics.

電池是一種由兩個或多個電化學電池組成的裝置，將儲存的化學能量轉化為電能。每個電池都有一個正極或陰極，還有一個負極。 V端子，或陽極。標記為正的端子具有比負端子更高的電勢能。標記為正的終端是當c時電子的來源。 連接到外部電路將流動和傳送能量到外部設備。當電池連接到外部電路時，電解液能夠以離子的形式在內部移動，從而使化學物質得以運行。 校準將在單獨的端子處完成并且因此將能量傳遞到外部電路。這就是這些離子在電池內的運動,其允許電流從電池中流出, Ry執(zhí)行工作。[1]雖然術語“電池技術”是指具有多個電池的器件，但是單個電池也被稱為電池。

一次(一次性或“一次性”)電池被一次性使用和丟棄，電極材料在放電過程中發(fā)生不可逆轉的變化。常見的例子是用于閃光燈的堿性電池。 緊身衣和許多便攜式設備。二次(可充電電池)可多次放電和充電；電極的原點可通過反向電流恢復。 租金。例子包括用于車輛的鉛酸電池和用于便攜式電子產(chǎn)品的鋰離子電池。

Batteries come in many shapes and sizes, from miniature cells used to power hearing aids and wristwatches to battery banks the size of rooms that provide standby power for telephone exchanges and computer data centers.

According to a 2005 estimate, the worldwide battery industry generates US$48 billion in sales each year,[2] with 6% annual growth.

Batteries have much lower specific energy (energy per unit mass) than common fuels such as gasoline. This is somewhat offset by the higher efficiency of electric motors in producing mechanical work, compared to combustion engines.

 電池有多種形狀和大小，從用于為助聽器和手表供電的微型電池到為電話交換機和comp提供備用電源的房間大小的電池組。 數(shù)據(jù)中心。根據(jù)2005年的估計，全球電池行業(yè)每年的銷售額為480億美元，年增長率為6%。電池的比能量(能量)要低得多。 (每單位質量y)比普通燃料(如汽油)。與內燃機相比，電機的機械工作效率更高，這在一定程度上抵消了這一現(xiàn)象。
