俄罗斯DELTA蓄电池DT4045  4V4.5AH电力驱动系统

胶体铅酸蓄电池采用凝胶状电解质，内部无游离液体存在，在同等体积下电解质容量大，热容量大，热消散能力强，能避免一般蓄电池易产生热失控现象;电解质浓度低，对极板的腐蚀作用弱;浓度均匀，不存在电解液分层现象。

胶体铅酸蓄电池在使用初期无法进行氧循环，这是因为胶体把正、负极板都包围起来了，正极板上面产生的氧气无法扩散到负极板，无法实现与负极板上的活性物质铅还原，只能由排气阀排出，与富液式蓄电池一致。

After using colloidal lead-acidbatteries for a period of time, the colloid begins to dry andcontract, producing cracks. Oxygen flows directly through thecracks to the negative electrode plate for oxygen circulation. Theexhaust valve is no longer frequently opened, and the colloidallead-acid battery is close to sealing operation, with little waterloss. Therefore, the main failure mechanism of electric bicyclebatteries is dehydration, and the use of colloidal lead-acidbatteries can achieve very good results. Colloidal electrolytecoagulates sulfuric acid electrolyte into colloidal substances byadding gel agent to the electrolyte. Generally, colloidalelectrolyte is also added with colloidal stabilizer andcompatibilizer, and some colloidal formulas are also added withdelayed colloidal coagulation and retarding agent to facilitatecolloidal filling.
