The chemical compositions of sei films formed on the interfaces of a3000 samples in different electrolytes during the first charging process are mainly li2co3 and lioco2r, but their textures are different. the sei films formed in ec - based electrolytes are thin and compact, which can prevent the solvated lithium ions from cointercalating between two graphene layers of the graphite crystallites effectively, therefore samples a3000 have small irreversible capacities and good compatibilities with this kinds of electrolytes. however, the sei films formed in pc - based electrolytes are thick but defective, which could not effectively prevent solvated lithium ions from intercalation, therefore sample a3000 shows large irreversible capacities in pc - based electrolytes and bad compatibilities with this kind of electrolytes

The results indicated that the dimension, shape and purity of base material could meet the functional demand of solid lubricant ; the thermal decomposition temperature of ptfe resin exceeds 400 c, but organic and inorganic packing filler added in ptfe made the water absorption rate of composite material increased, melting temperature and decomposition temperature decreased, in the meanwhile oxidative decomposition reaction was accompanied ; polar groups such as c = o, c - o - c and so on in the carbon fiber surface is advantageous to increase compatibility with other components and interlayer shearing strength ; uniform design experimental method could help to find the relationship between formula and frictional property by relatively small tests. the developing trend of each formula ' s friction coefficient could be showed by fitting curve ; the friction coefficient with no copper powder or graphite in formula was relatively big. this fact showed that copper powder and graphite should be used cooperatively ; it was found that when the ratio of copper powder to graphite by weight is 15 : 60, 30 : 30 - 40 and 60 : 15 - 30 respectively, the friction coefficient was relatively small. the degree of crystallinity of pure ptfe reached maximum by air cooling and the abrasion loss also reached maximum among three ones ; at the same time, the abrasion loss of solid lubricant sample was also the biggest among three ones ; when solid lubricant matched with 45 # steel axle or gcrl5 steel axle, lubricant transfer film could be formed on metal surface, thus direct contact between the surface of metal friction pair rings was reduced. their working life was elongated extremely ; there was mainly much graphite, a little ptff, moo3, feso4, cus and so on in lubricant transfer film
試驗結果表明：所選原料的尺寸、形狀及純度可滿足固體潤滑劑的性能要求；聚四氟乙烯樹脂熱分解溫度超過400 ，但在ptfe中加入無機填料會使復合材料吸水率提高，熔融溫度及分解溫度降低，且伴有氧化分解反應；碳纖維表面含有c = o及c - o - c等極性基團，有利於提高其與其它組分的相容性，提高層間剪切強度；均勻設計試驗方法能夠用較少的試驗次數找出配方與摩擦性能間的關系，擬合曲線基本能表示各配方的摩擦系數發展趨勢；配方中不加銅粉或不加石墨，其摩擦系數均較高，說明銅粉和石墨應該配合使用；當銅粉15份、石墨60份時，銅粉30份、石墨30 - 40份時，銅粉60 、石墨15 - 30份時，摩擦系數均具有較低值；純聚四氟乙烯樹脂在空氣冷卻時結晶度最大，磨損量也是三者中最大的；同時，固體潤滑劑試樣在空氣冷卻時的磨損量也是三者中最大的：不論是固體潤滑劑與45 #鋼軸配副或是固體潤滑劑鑲嵌入銅套后與gcr15鋼軸配副，在金屬表面均可形成潤滑轉移膜，從而減少金屬摩擦副表面間的直接接觸，大大延長其使用壽命;轉移膜中主要含有較多的石墨、少量聚四氟乙烯、 moo 。 -

The charging - discharging curves look like the letter " v " and have no flat plateaus due to the different sizes of the micropores. increasing the httmax, the micropores in ant samples become fewer and smaller, therefore the charging - discharging capacities decrease. when httmax = 2100, the charging - discharging capacity reaches the minimum since the number of the micropores reaches the minimum and the size of them become very small, the number of graphite crystallite in ant samples is still few and the size of them is also small
在htt _ （ max ） 2100的范圍內， ant試樣屬于亂層結構，石墨微晶尚未出現或數量很少，貯鋰機制為「孔隙貯鋰」 ，由於孔隙的大小不一，插鋰時克服阻力所需的電位也不同，因此充、放電曲線呈「 v 」字形，無平穩的充、放電電位平臺；隨著htt _ （ max ）的增大，試樣中孔隙逐漸變小、變少，充、放電容量也逐漸變小。 -
, the micropores became smaller and fewer, hence the charging - discharging capacity decreased. when httmax = 2000, the micropores nearly disappeared, the graphite microcrystals were few and small, therefore the charging - discharging capacities reached the minimum
Htt _ （ max ） = 2000時，微孔幾乎消失，而石墨微晶又少又小，因此試樣的充、放電容量最低。 -
