Apple研發可彎曲的電池

電池一定要是方的、圓的嗎？Apple可能會改變這個慣性，從USPTO的公開資料顯示，Apple正在研發一種可彎曲及非矩形的電池。
可彎曲的電池在製造過程中採用高溫加壓的方式，使其彎曲後在接合其他的材料、外殼而成透過電池的一端或多端使用彎曲設計，可安裝到彎曲或圓形的空間裡，藉此提升電子產品內部空間的使用率。
非矩形電池則是將一般矩形電池的正負極一端的部分材料去除，不僅可以改變電池厚度，也讓電池能夠呈現不規則形狀或圓弧形，更緊密的嵌入設備中。

Title : CURVED BATTERY CELLS FOR PORTABLE ELECTRONIC DEVICES
Filing Date : 2011.10.28.
Application Date : 2013.5.2.
Abstract :
The disclosed embodiments relate to the manufacture of a battery cell. The battery cell includes a set of layers including a cathode with an active coating, a separator, and an anode with an active coating. The battery cell also includes a pouch enclosing the layers, wherein the pouch is flexible. The layers may be wound to create a jelly roll prior to sealing the layers in the flexible pouch. A curve may also be formed in the battery cell by applying a pressure of at least 0.13 kilogram-force (kgf) per square millimeter to the layers using a set of curved plates applying a temperature of about 85.degree. C. to the layers.

Title : NON-RECTANGULAR BATTERIES FOR PORTABLE ELECTRONIC DEVICES
Filing Date : 2011.10.28.
Application Date : 2013.5.2.
Abstract :
The disclosed embodiments provide a battery cell. The battery cell includes a set of layers forming a non-rectangular shape, wherein the set of layers comprises a cathode with an active coating, a separator, and an anode with an active coating. The battery cell also includes a first conductive tab coupled to the cathode and a second conductive tab coupled to the anode. The layers are enclosed in a flexible pouch, and the first and second conductive tabs are extended through seals in the pouch to provide terminals for the battery cell. Furthermore, the non-rectangular shape is created by removing material from one or more of the layers.
