植保無人機電池由于要提供足夠的動力和續航給植保無人機作業，而植保機載重藥箱主要有20L/30L/40L/50L等這些，機載負重還是比較大的，因此植保無人機電池必須能支持足夠大的電流，所以植保無人機電池原材料配方與我們日常見到的手機，智能手表，AR/VR等3C電子產品使用的鋰電池有一定的差別。

目前，用于農作物噴灑農藥的無人機或者航拍用的無人機電池都(dou)屬(shu)于鋰聚(ju)合(he)物電(dian)(dian)(dian)池，正極(ji)為三元(yuan)材料(liao)，負極(ji)為人造石墨，單體電(dian)(dian)(dian)芯(xin)的電(dian)(dian)(dian)壓(ya)一(yi)般為3.7V，通過捆綁若干個單體電(dian)(dian)(dian)芯(xin)獲得高容量或者高電(dian)(dian)(dian)壓(ya)。

聚(ju)(ju)合(he)物(wu)鋰(li)離子(zi)(zi)(zi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)是指電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)解質(zhi)(zhi)(zhi)使用固(gu)(gu)體(ti)(ti)(ti)聚(ju)(ju)合(he)物(wu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)解質(zhi)(zhi)(zhi)的(de)(de)鋰(li)離子(zi)(zi)(zi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)。電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)由正極(ji)集流(liu)(liu)體(ti)(ti)(ti)、正極(ji)膜(mo)、聚(ju)(ju)合(he)物(wu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)解質(zhi)(zhi)(zhi)膜(mo)、負(fu)極(ji)膜(mo)、負(fu)極(ji)集流(liu)(liu)體(ti)(ti)(ti)緊壓(ya)復合(he)成(cheng)型，外包封鋁塑(su)復合(he)薄(bo)膜(mo)，并將(jiang)其(qi)邊(bian)緣熱熔封合(he)，得(de)到(dao)聚(ju)(ju)合(he)物(wu)鋰(li)離子(zi)(zi)(zi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)。其(qi)中(zhong)(zhong)固(gu)(gu)體(ti)(ti)(ti)聚(ju)(ju)合(he)物(wu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)解質(zhi)(zhi)(zhi)，以離子(zi)(zi)(zi)傳導電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)的(de)(de)固(gu)(gu)體(ti)(ti)(ti)材料，它(ta)包括(kuo)晶體(ti)(ti)(ti)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)解質(zhi)(zhi)(zhi)、玻(bo)璃電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)解質(zhi)(zhi)(zhi)和聚(ju)(ju)合(he)物(wu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)解質(zhi)(zhi)(zhi)3種類型，其(qi)中(zhong)(zhong)固(gu)(gu)體(ti)(ti)(ti)聚(ju)(ju)合(he)物(wu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)解質(zhi)(zhi)(zhi)因具(ju)有(you)質(zhi)(zhi)(zhi)輕、易(yi)成(cheng)膜(mo)、粘彈(dan)性好等(deng)(deng)優點，用于(yu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)、傳感器、電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)致變色顯示器、電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)容器等(deng)(deng)方面(mian)。將(jiang)固(gu)(gu)體(ti)(ti)(ti)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)解質(zhi)(zhi)(zhi)用于(yu)鋰(li)離子(zi)(zi)(zi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)，可(ke)排除液(ye)體(ti)(ti)(ti)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)解質(zhi)(zhi)(zhi)易(yi)泄露的(de)(de)問(wen)題，取代(dai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)中(zhong)(zhong)的(de)(de)隔離膜(mo)，抑(yi)制電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)表面(mian)枝(zhi)晶的(de)(de)產生(sheng)，降低電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)解質(zhi)(zhi)(zhi)與電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)的(de)(de)反應活性，提高(gao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)的(de)(de)比容量，使電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)具(ju)有(you)耐壓(ya)、耐沖(chong)擊、生(sheng)產成(cheng)本低、易(yi)于(yu)加工等(deng)(deng)優點。

常規的(de)(de)(de)(de)(de)(de)(de)固體(ti)(ti)(ti)(ti)聚(ju)合(he)(he)(he)物(wu)(wu)電(dian)(dian)解質(zhi)由(you)聚(ju)合(he)(he)(he)物(wu)(wu)、鋰(li)(li)鹽組(zu)成，它是鋰(li)(li)鹽溶于(yu)聚(ju)合(he)(he)(he)物(wu)(wu)而(er)形成的(de)(de)(de)(de)(de)(de)(de)電(dian)(dian)解質(zhi)體(ti)(ti)(ti)(ti)系(xi)。通常分(fen)子(zi)鏈上含有(you)能(neng)與Li+發生(sheng)配(pei)位作用的(de)(de)(de)(de)(de)(de)(de)氧(yang)、氮、硫等極性(xing)(xing)集團(tuan)的(de)(de)(de)(de)(de)(de)(de)聚(ju)合(he)(he)(he)物(wu)(wu)可用來形成該類體(ti)(ti)(ti)(ti)系(xi)，如聚(ju)氧(yang)化乙烯(xi)等。作為硬酸(suan)的(de)(de)(de)(de)(de)(de)(de)L計+傾向于(yu)和硬堿發生(sheng)相互作用，所(suo)以在(zai)含氧(yang)極性(xing)(xing)基團(tuan)的(de)(de)(de)(de)(de)(de)(de)聚(ju)合(he)(he)(he)物(wu)(wu)中(zhong)的(de)(de)(de)(de)(de)(de)(de)溶解度較大，PEO分(fen)子(zi)的(de)(de)(de)(de)(de)(de)(de)構(gou)(gou)象(xiang)比其他聚(ju)醚分(fen)子(zi)更有(you)利于(yu)與陽離(li)子(zi)形成多重配(pei)位，能(neng)溶解更多鋰(li)(li)鹽，表現(xian)出好(hao)的(de)(de)(de)(de)(de)(de)(de)導(dao)(dao)電(dian)(dian)性(xing)(xing)能(neng)。因此。目前市場上的(de)(de)(de)(de)(de)(de)(de)聚(ju)合(he)(he)(he)物(wu)(wu)鋰(li)(li)電(dian)(dian)池(chi)多屬于(yu)PEO體(ti)(ti)(ti)(ti)系(xi)的(de)(de)(de)(de)(de)(de)(de)固體(ti)(ti)(ti)(ti)電(dian)(dian)解質(zhi)，然而(er)，固體(ti)(ti)(ti)(ti)電(dian)(dian)池(chi)體(ti)(ti)(ti)(ti)系(xi)導(dao)(dao)電(dian)(dian)率畢竟不能(neng)像液體(ti)(ti)(ti)(ti)體(ti)(ti)(ti)(ti)系(xi)那樣，離(li)子(zi)可以自由(you)地(di)移動，大功(gong)率放電(dian)(dian)還是受到一定的(de)(de)(de)(de)(de)(de)(de)限制(zhi)，或(huo)者(zhe)在(zai)強制(zhi)大功(gong)率的(de)(de)(de)(de)(de)(de)(de)條件下運作，導(dao)(dao)致電(dian)(dian)池(chi)體(ti)(ti)(ti)(ti)系(xi)結構(gou)(gou)的(de)(de)(de)(de)(de)(de)(de)破(po)壞，從而(er)縮短了電(dian)(dian)池(chi)的(de)(de)(de)(de)(de)(de)(de)使用壽(shou)命，而(er)且稍微(wei)在(zai)低(di)溫的(de)(de)(de)(de)(de)(de)(de)條件下使用，聚(ju)合(he)(he)(he)物(wu)(wu)電(dian)(dian)池(chi)體(ti)(ti)(ti)(ti)系(xi)受到溫度的(de)(de)(de)(de)(de)(de)(de)影響會更明顯，表現(xian)出容量更低(di)，飛行(xing)時間越短。
