negative proton

A lot of experiments have been done in the process of exploiture soft packaging li - ion battery about how to choice the rational arts and crafts . the content include : how to deal with the collector , add how much pvdf in the material , how long the material need to stirring and the right viscidity , how much condubtivity agent the electrode need , what theckness is best , choice different collectors , the degree of dryness of the electrode , theckness of pressed model , how much electrolyte will be added , placement how long after added the electrolyte , system of formation how to influnce the battery , in formation the battery need or not need preesure from outside , how to vacuumize and the optimize matching positive pole and negative pole . with these practice make sure the parameter of the positive pole should less than 90 m ; according to different vacuumize order the conduc - tivity agent in anode will be 5mass % and 9mass % , respectively , and in cathode the data is 2mass % ; every 100mah added to 0 . 4 ml electrolyte ; before formation the battery should be placement 8 hours and the system of formation must be less than 0 . 01c before the voltage reach to 3 . 0v ; should press in outside when battery in formation ; to these batteries which capacity more than 350mah the vacuum time not excess 15s ; the optimize matching positive pole and negative pole between 2 . 10 : 1 and 2 . 15 : 1 . finally make out the battery which cycling performance and security are all very well 液態軟包裝鋰離子電池的研究主要是對關鍵工藝進行了優化設計,具體包括:集流體的處理、 pvdf的加入量、漿料攪拌時間和粘度、導電劑的加入量、電極膜的厚度、不同集流體的選擇、電極膜的干燥程度、壓型的厚度、電解液的加入量、注入電解液后靜置時間的長短、化成制度的影響、化成時電池所具有的壓力影響、抽真空的處理、正負極活性物質的匹配。最后確定出液態軟包裝鋰離子電池最佳工藝參數:正極膜的厚度小于90 m ;根據化成時不同抽真空順序,確定正極膜中的導電劑的加入量分別為5mass %和9mass % ;負極膜中導電劑的加入量為2mass % ;電解液的加入量為每100mah添加0 . 4ml ;化成前電池的靜置時間應當大于8h ;電池在3 . 0v之前采用小于0 . 01c的化成制度;在化成過程中應當施加一定的外部壓力;對于350mah的電池抽真空的延時不應大于15s ;而正負極活性物質的質量比應當在2 . 1 : 1 2 . 15 : 1之間。

By examining the new generation condutive polymer material 3 , 4 ? polyethylene dioxythiophene ( pedt ) , this paper investigated the edt monomer synthetic path and the optimum filming conditions of the compound pedt . based on this research , i also discussed the manufacturing processes and the related principles of the solid tantalum capacitors , when replacing the conventional inorganic material mno2 with the pedt as the negative pole 本文以新一代導電聚合物材料3 , 4 ?聚乙烯二氧噻吩( pedt )為研究對象,研究了edt單體合成路線及聚合物pedt的最佳成膜條件,并以此為基礎,討論了以導電聚合物有機材料pedt取代傳統的無機材料mno2作陰極的固體鉭電解電容器的制備工藝及相關機理。

The hit spot of elliptic shape appeared on crystal plane paralleling to c axis , and one half was brighter than the other half under sem . the brighter part was the negative pole , and the darker one was the positive pole 自發極化大的電氣石在平行于c軸的晶面上出現“啞鈴形”或長的“橢圓形”明暗對比的打擊斑,在垂直于c軸的端面上則出現無明暗對比的斑點。

( 3 ) by exploring the filming processes of the pedt negative pole , this paper , creatively using the vacuum single step method , has found a comparatively suitable processing condition ( 3 )通過對pedt陰極被膜工藝過程的研究,找到了較適合的單體m和氧化劑c配比,清洗液的配方和清洗時間,烘干溫度和時間,被膜和補形成次數等工藝參數。

We might find this division into positive and negative poles childishly simple ex ? cept for one difficulty : which one is positive , weight or light ? ness 我們會發現這種正反兩極得劃分似如此孩子氣的容易,只有一個出外:到底哪個更好?輕或者重?

The negative power is just like an electric pole that is negatively charged . without a negative pole , the lamp cannot shine 否定的力量,像電有兩極,一個是正極,一個是負極,如果沒有負極,燈不會亮。

Look at your battery holder , what can you see ? it ' s also has positive pole and negative pole 觀察你的電池座。你發現了什么嗎?仍舊有正極和負極。
