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、電極膜的乾燥程度、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。最後確定出液態軟包裝鋰離子電池最佳工藝參數:正極膜的厚度小於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於8h ;電池在3 . 0v之前採用小於0 . 01c的化成制度;在化成過程中應當施加一定的外部壓力;對於350mah的電池抽
真空的
延時不應大於15s ;而正負極活性物質的質量比應當在2 . 1 : 1 2 . 15 : 1之間。

From the analysis in theory, in the background of uncorrelated noise, the algorithms of lmstde, etde and etdge have good property in estimating delay. in the background of correlated noise, the lmstde is failed, but the etde and etdge can still estimate delay in sometime. their effect of estimation is strongly affected by the real time delay
