隨著可穿戴電(dian)子設(she)備(bei)的(de)(de)興起，具有(you)柔性(xing)(xing)的(de)(de)超薄(bo)(bo)(bo)印刷薄(bo)(bo)(bo)膜(mo)(mo)電(dian)池日(ri)漸成為科學(xue)(xue)家(jia)們(men)研(yan)究(jiu)的(de)(de)熱(re)點，特別是(shi)柔性(xing)(xing)鋅二氧化(hua)(hua)錳(meng)薄(bo)(bo)(bo)膜(mo)(mo)電(dian)池的(de)(de)出現，為該(gai)領域增添了(le)新的(de)(de)選擇(ze)可能性(xing)(xing)。而在(zai)包(bao)括有(you)機(ji)半導(dao)體(ti)(ti)薄(bo)(bo)(bo)膜(mo)(mo)晶(jing)體(ti)(ti)管在(zai)內的(de)(de)新技術紛(fen)(fen)紛(fen)(fen)涌現，但由于(yu)穩(wen)定性(xing)(xing)等(deng)局限性(xing)(xing)還(huan)無法應(ying)用(yong)于(yu)實際(ji)產品(pin)之上。據物(wu)理(li)(li)學(xue)(xue)家(jia)組織(zhi)網報道，近日(ri)發(fa)表(biao)在(zai)《應(ying)用(yong)物(wu)理(li)(li)學(xue)(xue)快(kuai)報》上的(de)(de)一篇研(yan)究(jiu)，提出了(le)一種新的(de)(de)柔性(xing)(xing)鋅二氧化(hua)(hua)錳(meng)薄(bo)(bo)(bo)膜(mo)(mo)電(dian)池。目前有(you)許多(duo)研(yan)究(jiu)都在(zai)致(zhi)力于(yu)提高有(you)機(ji)半導(dao)體(ti)(ti)薄(bo)(bo)(bo)膜(mo)(mo)晶(jing)體(ti)(ti)管的(de)(de)可用(yong)性(xing)(xing)，但經過努力后人們(men)發(fa)現，這類(lei)物(wu)質(zhi)靈活性(xing)(xing)低，化(hua)(hua)學(xue)(xue)鍵長，介質(zhi)層厚，無法滿足實際(ji)應(ying)用(yong)的(de)(de)要。因此，類(lei)似于(yu)鋅二氧化(hua)(hua)錳(meng)的(de)(de)堿性(xing)(xing)化(hua)(hua)學(xue)(xue)電(dian)池獲(huo)得了(le)更多(duo)的(de)(de)關注(zhu)。

發展薄(bo)膜(mo)印(yin)刷電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)的(de)(de)(de)(de)(de)一大動力是其(qi)(qi)可以通(tong)過制(zhi)(zhi)造(zao)柔(rou)性(xing)(xing)電(dian)(dian)(dian)子設備的(de)(de)(de)(de)(de)其(qi)(qi)余部件的(de)(de)(de)(de)(de)生產線(xian)來生產，從而提高集成(cheng)(cheng)(cheng)度，降低生產成(cheng)(cheng)(cheng)本。堿(jian)性(xing)(xing)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)與鋰離子電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)相比，原(yuan)料更為環保，無需密封(feng)，成(cheng)(cheng)(cheng)本更低。堿(jian)性(xing)(xing)化(hua)學電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)的(de)(de)(de)(de)(de)制(zhi)(zhi)造(zao)，采用(yong)模板印(yin)刷到纖維基(ji)材之上(shang)，可彎曲、能(neng)驅動柔(rou)印(yin)印(yin)刷電(dian)(dian)(dian)路(lu)，并滿足其(qi)(qi)所要的(de)(de)(de)(de)(de)性(xing)(xing)能(neng)特點(dian)。新研究中(zhong)，通(tong)過使(shi)用(yong)一種特殊的(de)(de)(de)(de)(de)制(zhi)(zhi)造(zao)工(gong)藝，研究人(ren)員能(neng)將(jiang)10個單元的(de)(de)(de)(de)(de)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)串聯(lian)起來組成(cheng)(cheng)(cheng)串聯(lian)電(dian)(dian)(dian)路(lu)，峰值電(dian)(dian)(dian)壓可達14伏，容量為0.8毫安時。這(zhe)種新型柔(rou)性(xing)(xing)鋅二氧化(hua)錳薄(bo)膜(mo)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)可采用(yong)目前商業上(shang)通(tong)用(yong)的(de)(de)(de)(de)(de)聚(ju)乙(yi)(yi)烯醇或聚(ju)乙(yi)(yi)烯纖維素薄(bo)膜(mo)為原(yuan)材料，使(shi)用(yong)100微(wei)米厚的(de)(de)(de)(de)(de)薄(bo)膜(mo)隔離鋅和二氧化(hua)錳電(dian)(dian)(dian)極并成(cheng)(cheng)(cheng)為其(qi)(qi)基(ji)板。疏水性(xing)(xing)氟聚(ju)合物溶液（特氟隆(long)AF）被印(yin)刷在兩個電(dian)(dian)(dian)極之間(jian)，以減(jian)少電(dian)(dian)(dian)解質的(de)(de)(de)(de)(de)遷移以及與相鄰的(de)(de)(de)(de)(de)其(qi)(qi)他電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)中(zhong)電(dian)(dian)(dian)極的(de)(de)(de)(de)(de)接觸。不同單元電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)用(yong)含銀的(de)(de)(de)(de)(de)印(yin)刷油墨連接。

研(yan)究(jiu)(jiu)人員(yuan)用(yong)100千歐(ou)電(dian)(dian)阻(zu)對這種柔性鋅二氧化錳薄(bo)膜(mo)電(dian)(dian)池(chi)進行(xing)了(le)放(fang)電(dian)(dian)測(ce)試(shi)。0.8毫安時(shi)的(de)電(dian)(dian)池(chi)經過7.5個小時(shi)的(de)放(fang)電(dian)(dian)，電(dian)(dian)壓從14伏下降到了(le)10伏。為了(le)確定其在(zai)真實(shi)的(de)印(yin)刷電(dian)(dian)路中的(de)性能(neng)，他們還對該電(dian)(dian)池(chi)進行(xing)了(le)與現實(shi)使用(yong)環境類似的(de)測(ce)試(shi)。研(yan)究(jiu)(jiu)人員(yuan)用(yong)由5個反相器首尾相連(lian)組(zu)成的(de)簡單(dan)電(dian)(dian)路進行(xing)測(ce)試(shi)，該電(dian)(dian)路的(de)輸出(chu)端(duan)對供電(dian)(dian)電(dian)(dian)壓和電(dian)(dian)路的(de)延遲十分(fen)(fen)敏感。結果顯(xian)示，該電(dian)(dian)路的(de)電(dian)(dian)壓波(bo)形在(zai)以10毫秒為單(dan)位(wei)的(de)測(ce)量(liang)中均保(bao)持在(zai)13伏左右。20分(fen)(fen)鐘后，沒有檢(jian)測(ce)到超過該幅度的(de)變化，這表(biao)明(ming)新電(dian)(dian)池(chi)有著較為穩定的(de)供電(dian)(dian)能(neng)力。研(yan)究(jiu)(jiu)人員(yuan)稱，更復(fu)雜的(de)電(dian)(dian)路或許要更大的(de)能(neng)量(liang)來推動，但柔性鋅二氧化錳薄(bo)膜(mo)電(dian)(dian)池(chi)至少為人們在(zai)現有的(de)印(yin)刷電(dian)(dian)池(chi)之外供應(ying)了(le)另外一個選擇。
