【摘要】：鎳氫電池由于具有無污染、能量密度高、無記憶效應(yīng)、安全性好、價格便宜等特點,成為最具發(fā)展前景的二次電池產(chǎn)品之一,廣泛應(yīng)用于各類電子產(chǎn)品、電動工具和混合電動汽車等產(chǎn)品。不同產(chǎn)品對鎳氫動力電池的要求是不一樣的,為了滿足用戶的多樣化和定制化需求,需要通過調(diào)整鎳氫動力電池的結(jié)構(gòu)、工藝和添加的元素成份,研制出相應(yīng)的鎳氫動力電池新產(chǎn)品。企業(yè)目前是根據(jù)經(jīng)驗和多次試制產(chǎn)品,來開發(fā)基本滿足客戶定制需求的鎳氫動力電池產(chǎn)品,耗時費力。為了解決企業(yè)的這個生產(chǎn)實際問題,本文提出應(yīng)用質(zhì)量機能展開(QFD)方法和可拓學(xué)創(chuàng)新方法,研究鎳氫動力電池新產(chǎn)品的設(shè)計方法,目的是快速開發(fā)出滿足用戶要求的鎳氫動力電池新產(chǎn)品。本文的主要研究內(nèi)容如下：首先,根據(jù)鎳氫動力電池的產(chǎn)品需求,建立產(chǎn)品規(guī)劃階段的質(zhì)量屋。綜合應(yīng)用親和圖法、層次分析法和模糊優(yōu)先規(guī)劃方法得到鎳氫動力電池的需求重要度以及工程技術(shù)特征權(quán)重。參考工程技術(shù)特征權(quán)重分析鎳氫動力電池產(chǎn)品的設(shè)計方案。然而,產(chǎn)品需求與工程技術(shù)特征之間存在沖突,如要求電池循環(huán)壽命高,則需要增加粘黏劑防止活性物質(zhì)的脫落,但會增加內(nèi)阻,內(nèi)阻的增加必然會影響電池的使用壽命。為了解決產(chǎn)品需求與工程技術(shù)特征之間的沖突問題,用可拓學(xué)的矛盾問題處理方法來建立鎳氫動力電池產(chǎn)品需求與工程技術(shù)特征之間的不相容問題可拓求解模型。采用可拓策略生成方法求解所建立的鎳氫動力電池不相容問題可拓求解模型。目標(biāo)基元為客戶需求,條件基元為鎳氫動力電池的工程技術(shù)特征,找出可拓求解模型中的核問題,對導(dǎo)電劑、極耳形狀和切片毛刺等所有相關(guān)的工程技術(shù)特征進行可拓變換,計算變換后的相容度函數(shù),使不相容問題轉(zhuǎn)化為相容問題,得到滿足客戶需求的鎳氫動力電池的設(shè)計方案。在上述方法的研究基礎(chǔ)上,改進極耳形狀和切片毛刺,利用石墨烯取代導(dǎo)電炭黑,與鎳氫電池的負(fù)極材料進行復(fù)合,試制出一種石墨烯鎳氫動力電池,通過電化學(xué)性能測試驗證了石墨烯鎳氫動力電池的優(yōu)越性能。
[Abstract]:The Ni-MH battery has become one of the most promising secondary battery products because of its characteristics of no pollution, high energy density, no memory effect, good safety and low price. It is widely used in all kinds of electronic products. Electric tools and hybrid electric vehicles and other products. Different products have different requirements for Ni-MH batteries. In order to meet the diversified and customized needs of users, the structure, process and added elements of Ni-MH batteries need to be adjusted. A new product of Ni-MH power battery has been developed. At present, the company develops nickel hydrogen battery products to meet the customer's custom requirements based on experience and many trial production, which is time-consuming and laborious. In order to solve this practical problem of production, this paper puts forward the application of QFDs and the innovative extension method to study the design method of the new product of Ni-MH power battery. The aim is to develop a new nickel-hydrogen battery product to meet the needs of customers. The main contents of this paper are as follows: firstly, according to the product demand of Ni-MH power battery, the quality house of product planning stage is established. The importance of requirement and the weight of engineering characteristics of Ni-MH power battery are obtained by using affinity graph method, AHP method and fuzzy priority programming method. The design scheme of Ni-MH power battery is analyzed with reference to the weight of engineering features. However, there is a conflict between product demand and engineering characteristics. If the battery cycle life is required to be high, it is necessary to increase the adhesive to prevent the active substances from falling off, but it will increase the internal resistance, and the increase of the internal resistance will inevitably affect the battery life. In order to solve the conflict between product demand and engineering technical characteristics, the extension solution model of incompatibility problem between product demand and engineering technical characteristics is established by using the contradiction problem treatment method of extension theory. The extension strategy generation method is used to solve the incompatibility problem of Ni-MH battery. The target element is the customer's requirement, the condition element is the engineering technical characteristic of the Ni-MH power battery, the nuclear problem in the extension solution model is found, and all the related engineering technical features, such as conductive agent, polar ear shape and slice burr, are transformed. By calculating the compatibility function after transformation, the incompatible problem can be transformed into a compatibility problem, and the design scheme of Ni-MH power battery can be obtained to meet the needs of customers. On the basis of the above methods, the shape of the electrode ear and the burr of the slice were improved, and the graphene instead of the conductive carbon black was used to compound with the negative electrode material of the Ni-MH battery to produce a kind of graphene Ni-MH power battery. The superior performance of Ni-MH battery was verified by electrochemical performance test.
