引言

鋰離子電池已經(jīng)成為了最為常用的電源之一，可以廣泛應(yīng)用于手機(jī)、平板、筆記本電腦等電子設(shè)備中。隨著電子產(chǎn)品的不斷更新和升級(jí)，人們對(duì)于鋰離子電池的容量、功率和壽命等方面提出了更高的要求。同時(shí)，隨著新能源領(lǐng)域的發(fā)展，電動(dòng)汽車和儲(chǔ)能系統(tǒng)等對(duì)于電池性能也提出了更高的要求。負(fù)極材料是實(shí)現(xiàn)鋰離子電池高容量的有效途徑之一。然而，目前使用的石墨材料的容量已經(jīng)趨于極限。因此，研發(fā)新型負(fù)極材料成為了鋰離子電池領(lǐng)域研究的熱點(diǎn)之一。

然而，新型負(fù)極材料的應(yīng)用面臨很多問(wèn)題，比如容量和環(huán)境穩(wěn)定性等。在實(shí)際應(yīng)用中，由于負(fù)極材料的膨脹和收縮，材料粉化和電極脫落等問(wèn)題，容易導(dǎo)致電池在循環(huán)使用過(guò)程中失效。為了克服這些限制，導(dǎo)電粘結(jié)劑在負(fù)極材料中的應(yīng)用變得越來(lái)越重要。

傳統(tǒng)的粘結(jié)劑主要是聚合物，其導(dǎo)電性和化學(xué)穩(wěn)定性不足以滿足高容量負(fù)極材料的需求。因此，尋求一種新型導(dǎo)電粘結(jié)劑以提高負(fù)極材料的穩(wěn)定性和性能顯得尤為重要。

本文研究了一種新型導(dǎo)電粘結(jié)劑，并評(píng)估了其在鋰離子電池高容量負(fù)極材料中的應(yīng)用。本文的內(nèi)容如下。

結(jié)果與分析

1.SEM表征

圖1顯示了樣品的SEM圖像。從圖中可以看出，導(dǎo)電粘結(jié)劑可以有效地保持負(fù)極材料的顆粒分布，并增加負(fù)極材料的機(jī)械穩(wěn)定性。

2.電化學(xué)性能測(cè)試

CCD測(cè)試結(jié)果顯示，導(dǎo)電粘結(jié)劑可以顯著提高負(fù)極材料的容量和循環(huán)性能。循環(huán)伏安測(cè)試結(jié)果顯示，導(dǎo)電粘結(jié)劑可以排除負(fù)極材料的機(jī)械穩(wěn)定性影響，從而提高負(fù)極材料的性能。

3.材料性能測(cè)試

導(dǎo)電粘結(jié)劑的導(dǎo)電性、機(jī)械性能和化學(xué)穩(wěn)定性在實(shí)驗(yàn)中得到了充分驗(yàn)證。結(jié)果表明，該導(dǎo)電粘結(jié)劑可以顯著提高負(fù)極材料的性能。
