style="font-size:16px;">干電池主要指用得多的鋅-二氧化錳電池，簡稱鋅錳電池。鋅錳電池是1868年法國人勒克朗謝發(fā)明的，1888年加斯納開始使鋅錳電池的液體組分不流動化而制得了干電池，1925年開始在二氧化錳合劑中使用乙炔炭黑，使干電池的放電和貯存性能提高60年代出現(xiàn)了以氫氧化鉀(或氫氧化鈉)為電解質(zhì)的堿性鋅錳電池。近二三十年來，鎳鎘電池、鋰電池等新型電池的開發(fā)應(yīng)用，雖然在能量密度、貯存性能、電壓精度以及可充電性等方面優(yōu)于鋅錳電池，但在價格性能比方面仍不如鋅錳電池，故鋅錳電池在市場上仍占主導(dǎo)地位。</span> </p> <p> <span style="font-size:16px;">干電池用炭黑包括乙炔炭黑、重油造氣副產(chǎn)炭黑及油爐法炭黑等。</span> </p> <p> <span style="font-size:16px;">乙快炭黑因其良好的導(dǎo)電性、高吸液性和高純凈度，在干電池應(yīng)用中占主導(dǎo)地位;重油造氣副產(chǎn)炭黑的導(dǎo)電性、吸液性好，但高純凈度的產(chǎn)品價格高昂因此用得不多;油爐法炭黑價格便宜，但吸液性、導(dǎo)電性較差，故用得也不多。</span> </p> <span

style="font-size:16px;">二氧化錳正極在干電池中通稱電芯或碳包，它是由二氧化錳、乙快炭黑、固體氯化銨和電解液混合而成。二氧化錳是正極中參與電化學(xué)反應(yīng)的成分，但它的導(dǎo)電性差，故加入石墨和乙快炭黑等導(dǎo)電組分導(dǎo)電組分并不參加成流反應(yīng)。石墨和乙炔炭黑皆有導(dǎo)電性，而乙塊幾黑還有顆粒細，非常疏松，表觀密度小的特點，其比表面積和吸濕能力大。加入石墨和乙快炭黑能使電芯中二氧化錳顆粒之間有良好的電子通道，在孔隙中電解液的擴散也比較暢通，從而提高二氧化錳的利用率。一般電芯粉料中二氧化錳含量在80％～89％之間，乙炔炭黑含量一般為10％以上，此外，還加上一定量的一般為干粉量的</span>

style="font-size:16px;">鋰電池還促進了長續(xù)航電動汽車的開發(fā)以及來自可再生能源（例如太陽能和風(fēng)能）的能量存儲，為實現(xiàn)一個無線（可移動）、無化石燃料的社會打下基石。可以說，鋰離子電池作為能源存儲器件，徹底地改變了人類的生活。</span> </p> <p> <span style="font-size:16px;">此次諾貝爾化學(xué)獎授予三位鋰電領(lǐng)域的科學(xué)家，是對每一位為鋰電池從無到有、從實驗室走向商業(yè)化做出貢獻的鋰電從業(yè)者的認可，是對仍在從事鋰電研究和志在繼續(xù)推動清潔、便攜社會發(fā)展的人們的激勵。</span> </p> <p> <span style="font-size:16px;">2

style="font-size:16px;">氣電池是化學(xué)電池的一種。構(gòu)造原理與干電池相似，所不同的只是它的氧化劑取自空氣中的氧。例如有一種空氣電池，以鋅為陽極，以氫氧化鈉為電解液，而陰極是多孔的活性炭，因此能吸附空氣中的氧以代替一般干電池中的氧化劑（二氧化錳）。日本正在推進空氣鎂電池的大容量化研究，該電池的工作原理為通過空氣中的氧氣和金屬鎂發(fā)生化學(xué)反應(yīng)產(chǎn)生電能。參與的機構(gòu)包括古河電池、尼康、日產(chǎn)汽車、日本東北大學(xué)、宮城縣日向市等產(chǎn)業(yè)界、學(xué)界、方面的11個單位。作為研究的首要任務(wù)步，古河電池計劃在年內(nèi)生產(chǎn)出發(fā)電量為300瓦的應(yīng)急電源，用于給手機等充電。日本企業(yè)陸續(xù)研發(fā)大幅提高空氣電池使用壽命的技術(shù)，使用壽命是有“蓄電池”之稱的空氣電池的比較大課題。富士通旗下的FDK公司開發(fā)的氫-空氣燃料電池有望3年后實用化</span><span

style="font-size:16px;">電池放電時所有這些能量都不能完全轉(zhuǎn)化為電能，電化學(xué)反應(yīng)總是伴隨著能量的損失，這些能量損失包括：1）活化極化--它引起電極表面的電化學(xué)反應(yīng) 2）濃差極化--它是由于電極表面和體相中反應(yīng)物和產(chǎn)物濃度的不同而產(chǎn)生的，是物質(zhì)傳遞的結(jié)果。極化的存在消耗了部分能量，并以熱的形式放出。</span> </p> <p> <span style="font-size:16px;">極化（polarization）</span> </p> <p> <span style="font-size:16px;">電池在充放電過程中是存在極化的，通?？蓪囯x子電池極化分為歐姆極化、電化學(xué)極化和濃差極化三類。幾類極化各自的響應(yīng)速度也不一樣。影響極化程度的因素很多，但一般情況下充放電電流密度越大，極化也就越大。</span> </p> <p> <span style="font-size:16px;">以下分類解釋一下：</span>
