The former four chapters form the first part , the first part starts from recognizing green battery , by analyzing the developing situation of battery in the world , summarizes the developing trait of battery industry , affirms the green battery industry ' s status in battery industry 前四章为第一部分，第一部分从认识绿色电池出发，通过分析世界电池的发展状况，总结出电池产业的发展特点，从而确认绿色电池产业在电池产业中的重要地位。
Ammonium chloride ( nh4cl ) , molecular weight 53 . 49 , corlorless cubic crystal or pulverous , taste briguet . it will sublimat or decompourd when heated and clot in dump weather . it is soluble and can black metal and other metal . it is mainly used in battery , storage battery , ammomium salt , tan , galvan oplasty , medicine , photo , electrode , adhesive and so on 49为无色立方结晶或粉末状，味咸凉，加热升华或分解，在潮湿阴雨天气，吸潮结块，易溶于水，对黑色金属和其它金属有腐蚀。
The present studies have proved that the most important factor which influences the performances of lithium metal anode in battery is the solid electrolyte interphase interface - film ( sei film ) on lithium anode . and how to make lithium metal anode have a sei film with favorable composition and stable configuration , or make the sei film have better stability , is the key to improve the electrochemistry performances of lithium metal anode in lithium secondary battery 已有的研究证明:影响金属锂负极在电池中性能的主要因素是其表面的固体电解质中间相界面膜( sei膜)的性能;如何使锂金属电极表面具有组成良好、结构稳定的sei膜,或者使锂电极表面sei膜能够更好的“稳定化” ,是提高锂二次电池中锂金属负极电化学性能的关键。
Besides all the functions and the advantages that the digital storage oscilloscope possesses , scopemeter have the functions of digital multi - meter . due to the features of small volume , little weight , low power consumption and built - in battery , scopemeter is especially fit for the field environment , no - power system , mobile occasion 手持式示波表不但秉承了数字存储示波器的所有测量功能和技术性能,并具有数字万用表测量功能,体积小、重量轻、功耗低、内置电池,特别适合于野外、机动等使用场合。
