Abstract
Description
本發明為有關一種海水電池，尤指一種陽極包含奈米碳管材料的海水電池。
The invention relates to a seawater battery, in particular to a seawater battery comprising an anode carbon nanotube material.
電池的結構隨著時代的進步而不斷的推陳出新，例如常見的乾電池、蓄電池、水銀電池、空氣電池、鎳鎘電池、鎳氫電池、鋰離子電池、太陽能電池、燃料電池、海水電池等，其中海水電池由於使用時才需與海水進行接觸發電，於平常貯存時電極不接觸電解液(海水)，不僅與一般電極需和電解質共同存放的蓄電池相比，其具有較佳的安全性，並且特別適合應用於與海洋相關又需要提供電力的產品。
於中國實用新型專利公告第CN2331087號中，即揭示一種海水電池，該海水電池主要由耐蝕的鋼陰極、海水電解液和多孔賤金屬陽極構成。其中，該多孔賤金屬陽極採用50至80微米的鋅-鋁合金粉和小於60微米的氧化鋁粉按3：1比例充分混合，由粉末冶金技術鑄造。製成的海水電池不但增加了陽極表面面積，而且保持了陽極活性物質參與化學反應的真實表面積。是一種能較穩定供應較大電流的海水電池。
然而，上述的多孔賤金屬陽極，在構成的該海水電池中產生約為400mA‧cm-2的電流密度，與該鋼陰極的有效電位差約為0.2V，而於電流密度方面偏小，故仍有改善的空間。
The structure of the battery has been continuously updated with the advancement of the times, such as common dry batteries, batteries, mercury batteries, air batteries, nickel-cadmium batteries, nickel-hydrogen batteries, lithium-ion batteries, solar cells, fuel cells, seawater batteries, etc. The battery needs to be in contact with seawater to generate electricity when it is used. The electrode does not contact the electrolyte (seawater) during normal storage, and it has better safety and is particularly suitable than the battery in which the general electrode needs to be stored together with the electrolyte. Used in products that are related to the ocean and need to provide electricity.
In Chinese Utility Model Patent Publication No. CN2331087, a seawater battery is disclosed, which is mainly composed of a corrosion resistant steel cathode, a seawater electrolyte and a porous tantalum metal anode. Wherein, the porous base metal anode is sufficiently mixed in a ratio of 3:1 with a zinc-aluminum alloy powder of 50 to 80 micrometers and an alumina powder of less than 60 micrometers, and is cast by powder metallurgy technology. The prepared seawater battery not only increases the anode surface area, but also maintains the true surface area of the anode active material involved in the chemical reaction. It is a seawater battery that can supply a relatively large current more stably.
However, the porous tantalum metal anode described above generates a current density of about 400 mA ‧ cm -2 in the seawater battery, and the effective potential difference from the steel cathode is about 0.2 V, and is small in terms of current density. There is room for improvement.

綜上所述，由於本發明利用奈米碳管製造海水電池的電極(該陽極以及該陰極)，藉由奈米碳管的高活性與高比表面積，而提供離子移動的通道，提高因該電位差所形成的該電流之電流密度，於電位差為1.4至2V時，該電流的電流密度最高可達到650mA‧cm-2，有效提升該海水電池的供電效能。再者，本發明利用該奈米碳管做為海水電池的電極，可降低該電極於該電化學反應中的消耗，進一步延長該海水電池的使用壽命。
本發明尤其適合應用於航行於海中之船舶或建構於海上之設施，提供其所需之電力，但本發明並不限於此，原則上可廣泛適用在任何含有海水之環境。與傳統的火力發電相較，本發明海水電池的運作過程，並不會產生有危環境的物質；而與水力發電相比，又不會因建築的關係影響生態環境，故屬於環保的發電方式。此外，相對於太陽能電池，本發明海水電池毋須受限於日照時間或天候條件，僅需利用海水做為電解液，即可發電，故可提供較穩定的發電量。因此本發明極具進步性及符合申請發明專利的要件，爰依法提出申請，祈鈞局早日賜准專利，實感德便。
以上已將本發明做一詳細說明，惟以上所述者，僅爲本發明的一較佳實施例而已，當不能限定本發明實施的範圍。即凡依本發明申請範圍所作的均等變化與修飾等，皆應仍屬本發明的專利涵蓋範圍內。
