聚合物鋰電池是(shi)鋰(li)(li)(li)電(dian)(dian)(dian)(dian)池的(de)類型。鋰(li)(li)(li)可充電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)池的(de)充電(dian)(dian)(dian)(dian)和(he)放(fang)電(dian)(dian)(dian)(dian)功能依賴于正(zheng)極(ji)(ji)和(he)負(fu)極(ji)(ji)之間的(de)移動(dong)。在充電(dian)(dian)(dian)(dian)和(he)放(fang)電(dian)(dian)(dian)(dian)期間，鋰(li)(li)(li)離子被充入正(zheng)極(ji)(ji)和(he)負(fu)極(ji)(ji)中; 鋰(li)(li)(li)電(dian)(dian)(dian)(dian)池材(cai)料(liao)通常是(shi)包含在鋰(li)(li)(li)正(zheng)電(dian)(dian)(dian)(dian)極(ji)(ji)或(huo)通過電(dian)(dian)(dian)(dian)解質的(de)負(fu)電(dian)(dian)(dian)(dian)極(ji)(ji)材(cai)料(liao)，并且是(shi)近年來(lai)出現(xian)的(de)高能電(dian)(dian)(dian)(dian)池的(de)代表。

聚(ju)(ju)合物(wu)鋰電(dian)(dian)池(chi)(chi)是(shi)特(te)殊的(de)，因為(wei)聚(ju)(ju)合物(wu)鋰電(dian)(dian)池(chi)(chi)和其他常規鋰電(dian)(dian)池(chi)(chi)的(de)電(dian)(dian)解(jie)(jie)(jie)(jie)質(zhi)不(bu)同。常規鋰電(dian)(dian)池(chi)(chi)使(shi)用的(de)是(shi)液體電(dian)(dian)解(jie)(jie)(jie)(jie)質(zhi)和聚(ju)(ju)合物(wu)鋰電(dian)(dian)池(chi)(chi)使(shi)用新型固體電(dian)(dian)解(jie)(jie)(jie)(jie)質(zhi)。但使(shi)用的(de)正(zheng)極(ji)材(cai)料與負極(ji)材(cai)料相同。鋰電(dian)(dian)池(chi)(chi)的(de)液體電(dian)(dian)解(jie)(jie)(jie)(jie)質(zhi)可以(yi)由固體電(dian)(dian)解(jie)(jie)(jie)(jie)質(zhi)來代替(ti)，這樣就是(shi)聚(ju)(ju)合物(wu)鋰電(dian)(dian)池(chi)(chi)，它(ta)們可以(yi)做成(cheng)任何(he)形(xing)狀。在(zai)電(dian)(dian)池(chi)(chi)盒上使(shi)用傳(chuan)統的(de)輕質(zhi)外(wai)殼，整個電(dian)(dian)池(chi)(chi)的(de)能(neng)量(liang)由密(mi)度鋼或鋁(lv)(lv)殼電(dian)(dian)池(chi)(chi)，鋁(lv)(lv)塑復合膜操縱。因此，聚(ju)(ju)合物(wu)鋰電(dian)(dian)池(chi)(chi)是(shi)由具(ju)有(you)高聚(ju)(ju)合物(wu)固體電(dian)(dian)解(jie)(jie)(jie)(jie)質(zhi)組成(cheng)，成(cheng)本遠(yuan)遠(yuan)超過液體電(dian)(dian)解(jie)(jie)(jie)(jie)質(zhi)鋰電(dian)(dian)池(chi)(chi)，目前(qian)是(shi)智(zhi)能(neng)設(she)(she)備，移動電(dian)(dian)話(hua)，平板計算(suan)機，以(yi)及(ji)航模，車模，無人機等和可佩戴設(she)(she)備的(de)使(shi)用電(dian)(dian)池(chi)(chi)之一。

聚合物(wu)鋰(li)電(dian)(dian)池需要注意短(duan)路(lu)(lu)(lu)情(qing)(qing)況，聚合物(wu)鋰(li)電(dian)(dian)池在(zai)充電(dian)(dian)期間易于發(fa)生短(duan)路(lu)(lu)(lu)。包括(kuo)：內(nei)部短(duan)路(lu)(lu)(lu)，外(wai)部短(duan)路(lu)(lu)(lu)等(deng)。但是大多數鋰(li)離子電(dian)(dian)池在(zai)現(xian)在(zai)都具有抗短(duan)路(lu)(lu)(lu)的保護和接線，在(zai)許多情(qing)(qing)況下，這種保護電(dian)(dian)路(lu)(lu)(lu)不一定能在(zai)各種情(qing)(qing)況下工作(zuo)，并(bing)且在(zai)電(dian)(dian)線中只能起到(dao)有限的防止短(duan)路(lu)(lu)(lu)的作(zuo)用。

聚合物鋰電池，如(ru)果充電時間過長(chang)，膨脹的(de)可(ke)能性就會增大。鋰的(de)化學性質(zhi)非常(chang)具(ju)有侵蝕性且(qie)易(yi)于燃燒。在激活(huo)過程(cheng)中，電池的(de)內部壓力增加達到(dao)一定的(de)壓力水平且(qie)產生(sheng)的(de)氣體膨脹。如(ru)果外殼被劃傷，它會爆裂。發生(sheng)泄漏，火災(zai)甚至爆炸。由于高生(sheng)產要(yao)求使得難以清(qing)潔聚合物電解質(zhi)系統，因此(ci)成本相對(dui)較高。
