引言

與一般材料相比，納米儲(chǔ)能材料表現(xiàn)出了優(yōu)越的性能，為了加快納米儲(chǔ)能這一新興產(chǎn)業(yè)的健康發(fā)

展，規(guī)范納米儲(chǔ)能材料性能測(cè)試方法成為業(yè)內(nèi)亟需完成的工作。在這方面，國(guó)際電工委員會(huì)電工產(chǎn)品和

系統(tǒng)納米技術(shù)委員會(huì)（IEC/TC113）已經(jīng)發(fā)布了8項(xiàng)關(guān)于納米儲(chǔ)能材料性能測(cè)試的標(biāo)準(zhǔn)化文件，結(jié)合

國(guó)內(nèi)產(chǎn)業(yè)發(fā)展需要，擬對(duì)相關(guān)標(biāo)準(zhǔn)進(jìn)行采標(biāo)。GB/T41232《納米制造關(guān)鍵控制特性納米儲(chǔ)能》是

指導(dǎo)納米儲(chǔ)能材料物理性能和化學(xué)性能測(cè)試方法的標(biāo)準(zhǔn)，擬由8個(gè)部分構(gòu)成。

—第1部分：納米正極材料的電化學(xué)性能測(cè)試

兩電極電池法。目的在于確立采用兩電極電池法測(cè)

試納米正極材料電化學(xué)性能的相關(guān)規(guī)定。

—第2部分：納米正極材料的密度測(cè)試。目的在于確立測(cè)試納米正極材料密度的相關(guān)規(guī)定。

—第3部分：納米材料接觸電阻率和涂層電阻率的測(cè)試。目的在于確立測(cè)量納米電極材料接觸電

阻率和涂層電阻率的相關(guān)規(guī)定。

測(cè)試納米正極材料電化學(xué)性能的相關(guān)規(guī)定。

—第6部分：納米電極材料中的碳含量測(cè)定紅外吸收法。目的在于確立采用紅外光譜吸收法測(cè)

定納米電極材料碳含量的相關(guān)規(guī)定。

—第7部分：納米正極材料中磁性雜質(zhì)的測(cè)定ICP?OES法。目的在于確立使用電感耦合等離子

體發(fā)射光譜儀（ICP?OES）測(cè)定納米正極材料中磁性雜質(zhì)的相關(guān)規(guī)定。

—第8部分：納米電極材料中水分含量的測(cè)定卡爾·費(fèi)休庫(kù)倫滴定法。目的在于確立采用卡爾·費(fèi)

休庫(kù)侖滴定法測(cè)定納米電極材料中水分含量的相關(guān)規(guī)定。

納米儲(chǔ)能技術(shù)已廣泛應(yīng)用于便攜式電子設(shè)備、電動(dòng)汽車和儲(chǔ)能系統(tǒng)等領(lǐng)域。這些應(yīng)用的持續(xù)快速發(fā)

展對(duì)納米儲(chǔ)能器件的性能提出了更高的要求。電能儲(chǔ)存器件的主要性能取決于電極材料。

納米電極材料的碳含量是一個(gè)重要控制指標(biāo)，碳含量會(huì)影響電極材料的性能和質(zhì)量。碳作為導(dǎo)電

劑，能提高粒子間的電子傳導(dǎo)性能，因此合適的碳含量是必要的。一方面。當(dāng)碳含量不足時(shí)，導(dǎo)電性能

得不到有效改善，導(dǎo)致電池的內(nèi)阻高、放電平臺(tái)低或容量小，從而使得其倍率性能和循環(huán)壽命下降。但

另一方面，碳含量過高則容易相互聚集且難以分散，會(huì)影響后續(xù)加工，因?yàn)檫^量的碳會(huì)降低活性物質(zhì)的

占比，影響電池的能量密度。

由于納米電極材料的顆粒粒徑較小、表觀密度低，測(cè)試過程中，樣品在爐膛內(nèi)很容易被氣體吹走，

不僅影響碳含量的測(cè)定，而且可能污染測(cè)試系統(tǒng)。本文件通過特殊的制樣方式─粉末壓片，提供了一

種應(yīng)用于電能儲(chǔ)存裝置中的納米電極材料碳含量的測(cè)定方法，用于評(píng)估納米電極復(fù)合材料配方的最佳組

合，避免樣品損失的同時(shí)保護(hù)了儀器。依據(jù)該方法，能比較不同研究團(tuán)隊(duì)的結(jié)果。

本方法僅適用于比較研究階段納米電極材料中的碳含量，而不適用于評(píng)估終端產(chǎn)品中的電極材料。

本方法適用于只有通過納米技術(shù)才能展現(xiàn)出功能或性能的材料，有意地將其添加到活性材料中能顯

著提高電儲(chǔ)能器件的性能。
