arallel Connection This configuration provides maximum design flexibility. CAPACITY Sealed Lead Acid (SLA): The first thing that es to mind while talking about these kinds of batteries is that, They are not portable or easy to carry around because of their weight and size. They are the oldest type of rechargeable batteries and have a voltage/cell of . They have a low energy to volume ratio but they can supply high surge currents which gives them a Good power to weight ratio. This kind of high surge current makes them useful In automobiles, invertors, boats, fork lifts or golf carts. Sealed Lead Acid batteries, similar in design to the battery that your car uses, are one of the oldest battery technologies going, and yet their unique attributes mean that for some applications there is no viable substitute. Although not disposable due to toxic lead acid ponents, SLA batteries are easily recycled. They charge much more slowly than the other battery technologies (up to 5x slower), but are able to provide larger amounts of power to support larger appliances, and are very tolerant to overcharge undercharge.

They also have a voltage/cell of . These have been around since the mid 19th century and were the only batteries used until World War II. They have low energy density and perform poorly under high current application. In spite of such disadvantages they are used in everyday applications such as Penlights, Personal care devices and motor driven devices. 鹼性電池 ? 鹼性電池的發(fā)展,主要被用於需要高電流使用的裝置,以代替較不實(shí)用的碳鋅電池。鹼性電池與碳鋅電池最大的差異,乃在於鹼性電池使用高濃度的鹼性氫氧化鉀 (Potassiumhydroxide)做電解液。但它與碳鋅電池的電流密度足一樣。 ? 汞電池,其陽極 (負(fù)極 )是鋅一汞合金,而陰極是氧化汞,亦是去極劑。汞電池放在電池架上,如不使用,幾乎不會(huì)漏電 。 氧化銀電池 ? 氧化銀電池跟汞電池一樣,其放電電壓曲線亦極為平穩(wěn)。其正極 (陰極 )乃氧化銀和二氧化錳的去極氧化物,隨著應(yīng)用的不同,其混合物的成分就不一樣 。 ? 氧化銀電池的壽命很長(zhǎng),而且其在高溫時(shí),其功能不受影饗 。然而,如果其他型式的氧化銀電池,高價(jià)格因素不予考慮的話,則密封型及開口型電池的應(yīng)用將受到限制。 ? 鎳鎘電池最著名的缺點(diǎn),就是所謂的「記憶效應(yīng)」,也就是當(dāng)電池裡還有沒用完的電,就再充電時(shí),電池就會(huì)「記得」這個(gè)位置,以後電用到剩這麼多時(shí),電池就會(huì)發(fā)生和沒電一樣的反應(yīng)(電壓瞬間降低)。大部份應(yīng)用中它都已經(jīng)被相近的鎳氫電池( NiMH)所取代。不過受到記憶效應(yīng)的影響,效能會(huì)隨充放電次數(shù)增加而下降。鎳氫電池最大的問題,是它有很高的自放電率,也就是明明是充飽電的電池,放在一邊不用一個(gè)月,電力可以少掉 30% 之譜。這些額外的電路和機(jī)構(gòu),是為什麼沒有三號(hào)/四號(hào)大小的鋰離子電池,以及為什麼筆電電池價(jià)格如此高昂的原因。c 環(huán)境下的鋰電池可以在三個(gè)月內(nèi)減掉 40% 的蓄電力。 Lithiumion polymer battery 充電過程與充電方法 ? 電池的充電過程通??煞譃轭A(yù)充電、快速充電、補(bǔ)足充電、涓流充電四個(gè)階段??焖俪潆娝俾室话阍?1C以上,快速充時(shí)間由電池容量和充電速率決定。只要電池接到充電器上,低速率恆流充電器就能對(duì)電池提供很小的涓流充電電流。大部分涓流充電器中,都沒有任何電壓或溫度回饋控制,因而不能保證電池充足電后,立即關(guān)斷充電器。一次大放電把電用乾,再充到全飽應(yīng)該就能將保護(hù)回路「校正」回來。如果再把電池丟到冰箱裡,效果更好 ... ? 電池收起來時(shí),留約 40% 的電在裡面 留太多會(huì)蓄電量降低的問題,留太少電池會(huì)損壞。其他的保養(yǎng)原則都和鋰離子電池一樣(所以用鋰電池的手機(jī)寧可天天充電,也不要用光電了才充)。 ? ,以免電池液漏出傷到肌膚或眼睛。 ? ,以免電池內(nèi)的重金屬在自然環(huán)境中釋放出來污染土壤及水源,威脅自己及後代的生存。我們除了將廢手機(jī)電池回收,其實(shí)也可以減少?gòu)U手機(jī)電池的產(chǎn)生,那就是按照電池生產(chǎn)廠商提供的充電步驟與用法正確使用電池,這樣不但延長(zhǎng)電池壽命,相對(duì)就會(huì)減少?gòu)U電池?cái)?shù)量,降低廢棄電池對(duì)環(huán)境的污染。 ? ,雖然鎳鎘電池比較便宜,但是最好購(gòu)買不含鎘金屬,比較環(huán)保的鎳氫電池是一種安全可靠、有利於環(huán)保的電池。若濺入眼內(nèi),用清水沖眼至少 15分鐘並及時(shí)就醫(yī)。 ? 。這讓鋰聚合電池可以做成各式各樣的形狀(對(duì)消費(fèi)者來說可不是好事 = =),符合不同的
