熟悉無人機的朋友知道，以格氏TATTU為例，一塊10000毫安的無人機電池售價近1000塊，而我們平時用的充電寶20000毫安的價格也就一兩百元(比如下面的這款小米充電寶)，為什么差別這么大？把20000毫安的充電寶電池用到無(wu)人機上續航不(bu)是更久(jiu)?

這是因為無人機采用的聚合物鋰離子電池， 這和(he)充電寶所采用的18650電池(chi)有所不同(tong)。之所以價格要(yao)貴(gui)很多，這是因為(wei)相比于其他數碼設備，無人機對電池(chi)的要(yao)求更(geng)為(wei)嚴(yan)格，因此價格上要(yao)直線上升。

從(cong)性能(neng)(neng)方面說，無(wu)人機需(xu)要(yao)克服自身的(de)(de)(de)重力做功(gong)(gong)(gong)(gong)，因此，對于電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)的(de)(de)(de)重量(liang)要(yao)求(qiu)較高(gao)，而(er)(er)增大(da)(da)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)容(rong)量(liang)又(you)會導致重量(liang)增加，因此只(zhi)有同(tong)樣(yang)(yang)容(rong)量(liang)下重量(liang)較輕的(de)(de)(de)聚合(he)物(wu)鋰離子電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)能(neng)(neng)夠(gou)(gou)滿足(zu)(zu)需(xu)求(qiu)；另一(yi)(yi)方面，無(wu)人機對于電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)的(de)(de)(de)功(gong)(gong)(gong)(gong)率(lv)(lv)的(de)(de)(de)要(yao)求(qiu)特別高(gao)，當從(cong)懸停狀態迅速提高(gao)油(you)門到(dao)最高(gao)速度，電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)功(gong)(gong)(gong)(gong)率(lv)(lv)會迅速提高(gao)，短時間(jian)內(nei)幾倍的(de)(de)(de)功(gong)(gong)(gong)(gong)率(lv)(lv)提高(gao)，這樣(yang)(yang)的(de)(de)(de)功(gong)(gong)(gong)(gong)率(lv)(lv)變化(hua)只(zhi)有聚合(he)物(wu)鋰離子電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)能(neng)(neng)夠(gou)(gou)滿足(zu)(zu)。實(shi)際上(shang)18650電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)通過(guo)串并聯也能(neng)(neng)達到(dao)這樣(yang)(yang)的(de)(de)(de)要(yao)求(qiu)，特斯(si)拉汽車(che)的(de)(de)(de)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)便是(shi)7000多(duo)塊18650電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)串并聯在(zai)一(yi)(yi)起，從(cong)而(er)(er)能(neng)(neng)夠(gou)(gou)承受瞬間(jian)的(de)(de)(de)大(da)(da)功(gong)(gong)(gong)(gong)率(lv)(lv)需(xu)求(qiu)，這在(zai)無(wu)人機上(shang)明(ming)顯不(bu)適合(he)。因此，從(cong)性能(neng)(neng)上(shang)來(lai)說，只(zhi)有聚合(he)物(wu)鋰離子電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)能(neng)(neng)夠(gou)(gou)滿足(zu)(zu)這樣(yang)(yang)的(de)(de)(de)使(shi)用需(xu)求(qiu)。

當(dang)然即使是聚(ju)合(he)物鋰離子(zi)電(dian)池(chi)在無人機上損耗(hao)也非(fei)(fei)常(chang)快，一塊5800mah的(de)電(dian)池(chi)只能(neng)支(zhi)撐(cheng)30分鐘的(de)飛行時(shi)(shi)間，可以想象對電(dian)池(chi)的(de)壓力有多大，聚(ju)合(he)物鋰離子(zi)電(dian)池(chi)長期(qi)在這種工(gong)作環境下，電(dian)池(chi)損耗(hao)非(fei)(fei)常(chang)快，并且(qie)短時(shi)(shi)間內快速(su)放電(dian)也會導(dao)致電(dian)池(chi)溫(wen)度快速(su)升(sheng)高，這些(xie)都使得(de)無人機電(dian)池(chi)需要更進一步的(de)安全保護。

因此，不(bu)論是(shi)從性(xing)能(neng)還是(shi)安全角度考慮(lv)，無人(ren)機(ji)所(suo)使用的電(dian)池(chi)(chi)要(yao)求都要(yao)比普(pu)通的充(chong)電(dian)寶所(suo)用的18650電(dian)池(chi)(chi)要(yao)高(gao)，這也(ye)使得其價格高(gao)昂。

而格(ge)氏的(de)(de)無(wu)人機電(dian)池(chi)則以高倍率(lv)、大容量(liang)的(de)(de)卓越(yue)性(xing)能著稱，爆發力極強，可(ke)以完全(quan)(quan)滿足(zu)無(wu)人機的(de)(de)起飛需(xu)求。另(ling)外，格(ge)氏掌握著多項(xiang)鋰聚合物電(dian)池(chi)核心技術，在續(xu)航、安全(quan)(quan)性(xing)方面也表現優(you)異(yi)，損耗(hao)慢、使用(yong)壽命更(geng)長(chang)。目前在無(wu)人機各個(ge)應用(yong)領域，格(ge)氏皆有與之相(xiang)對應的(de)(de)電(dian)池(chi)。
