你有沒有想過為什麼你的手機可以工作?可能不會。但是,如果你仔細想想,所有便攜式設備都依靠電池來保持滴答作響 - 有些電池的壽命比其他電池壽命還要長。這就是為什麼我們要看看手機是什麼讓滴答滴答,以及為什麼有些電池比別人好。

鋰離子聚合物電池


鋰離子電池


鋰離子電池於1912年開始發展,但直到1991年被索尼采用才開始普及。鋰離子電池的能量密度高,成本低於鋰聚合物電池。另外,初次使用時不需要啟動,而且自放電低。但是,即使不使用,鋰離子電池也會老化。

Discharge Rate Flat
Recharge Life 300 – 400 cycles for 100%
Charging Temperature 32º F to 140º F (0º C to 60º C)
Storage Life Loses less than 0.1% per month.
Storage Temperature -4º F to 140º F ( -20º C to 60º C)
Other Notes
  • Typically designed to be recharged in the device rather than in an external charger.
  • The chemical construction of this battery limits it to a rectangular shape.
  • Lighter than nickel-based secondary batteries with (Ni-Cd and NiMH).



鋰聚合物電池


鋰聚合物電池可以追溯到20世紀70年代。他們的第一個設計包括一個類似於塑料薄膜的干燥固體聚合物電解質。因此,這種類型的電池可以導致信用卡薄設計,同時仍然保持相對較好的電池壽命。另外,鋰聚合物電池非常輕巧,安全性也有所提高。然而,這些電池的製造成本更高,並且比鋰離子電池的能量密度更差。

Type Secondary
Chemical Reaction Varies, depending on electrolyte.
Operating Temperature Improved performance at low and high temperatures.
Recommended for Cellular telephones, mobile computing devices.
Initial Voltage 3.6 & 7.2
Capacity Varies depending on the battery; superior to standard lithium-ion.
Discharge Rate Flat
Recharge Life 300 – 400 cycles
Charging Temperature 32º F to 140º F (0º C to 60º C)
Storage Life Loses less than 0.1% per month.
Storage Temperature -4º F to 140º F ( -20º C to 60º C)
Other Notes
  • Typically designed to be recharged in the device rather than in an external charger.
  • Lighter than nickel-based secondary batteries with (Ni-Cd and NiMH).
  • Can be made in a variety of shapes.



儘管鋰聚合物電池更薄更薄,但是鋰離子電池具有更高的能量密度和更低的製造成本。因此,我們顯然知道三星,蘋果,摩托羅拉等公司選擇哪一個。最後,經常加入新的化學物質等等,誰知道長遠來看,哪一個會出現在最前面。我們唯一知道的就是這款手機將採用非常薄且透明的鋰離子電池。
