總體而言，本發明之電池樣品(A+C)除了於20小時率電容量測試之外，其他如5小時率電容量測試、保留容量測試、冷起動電流測試、高率放電特性測試及充電接收性測試等性能，都優於其他電池樣品之性能，可見將活性碳與碳黑混合作為活性物質之碳材添加物作成之負極，可以將此二種材料之電化學特性優點加成比添加各單一碳材之電化學特性還要好，尤其是在高率充、放電性能方面，而在上面之實驗中可以看出本次研究顯示，添加較高比率(0.8%)比添加較低比率(≦0.4%)碳材之負極活性物質所表現之電化學特性較好，然而實際上在負極添加高比例之碳材係十分困難，通常於總體添加超過2wt%後難度就 會大幅提升，甚至於越接近2wt%添加難度也越高，因此綜合實驗及實際限制後，得出本發明之最佳碳材添加比例為活性碳0.6wt%及碳黑0.7wt%，在此碳材配比下，會同時兼顧添加難度及電池效能，以讓電池製程更有效率。 In general, the battery samples (A+C) of the present invention, in addition to the 20-hour rate capacitance test, other such as 5-hour rate capacitance test, retention capacity test, cold start current test, high-rate discharge characteristic test and charging The receptivity test and other performances are better than those of other battery samples. It can be seen that the negative electrode made by mixing activated carbon and carbon black as the carbon material additive of the active material can be added in an additive ratio of the electrochemical characteristics of the two materials. The electrochemical characteristics of each single carbon material are even better, especially in terms of high-rate charge and discharge performance. It can be seen from the above experiment that this study shows that the higher rate of addition (0.8%) is higher than the lower rate of addition ( ≦0.4%) The electrochemical characteristics of the negative electrode active material of carbon materials are better. However, it is actually very difficult to add a high proportion of carbon materials to the negative electrode. Usually, it is difficult to add more than 2wt% in total. It will be greatly increased, even the closer to 2wt%, the more difficult it is to add. Therefore, after comprehensive experiments and practical restrictions, it is concluded that the optimal carbon material addition ratio of the present invention is 0.6wt% of activated carbon and 0.7wt% of carbon black. Under the carbon material ratio, the difficulty of adding and battery performance will be taken into consideration at the same time to make the battery manufacturing process more efficient.
請續參閱第7圖至第10圖，其係為不同電池樣品之負極SEM圖。如圖所示，由於碳材的導電度及表面(粗糙度)與負極活性物質的電化學反應性能及電容量相關，尤其是高率充、放電性能，而從第10圖(本發明)之SEM照片中可以看出將碳材A與碳材C混合後，碳材的表面積及粗糙度便可增加，進而使負極在充、放電時可加速鉛的成核及電化學反應性能，以透過另一種方式展現本發明之進步性。 Please continue to refer to Figures 7 to 10, which are SEM images of the negative electrode of different battery samples. As shown in the figure, since the conductivity and surface (roughness) of the carbon material are related to the electrochemical reaction performance and capacitance of the negative electrode active material, especially the high-rate charge and discharge performance, from Figure 10 (the present invention) It can be seen from the SEM photo that the surface area and roughness of the carbon material can be increased after the carbon material A and the carbon material C are mixed, so that the negative electrode can accelerate the nucleation of lead and the electrochemical reaction performance during charging and discharging. Another way shows the advancement of the present invention.
綜上所述，本發明在提供全新的碳材配比後，確實使新的碳鉛電池具有較好的效能，進而展現出本發明之新穎性和進步性。 In summary, after the present invention provides a brand-new carbon material ratio, the new carbon-lead battery does have better performance, thereby demonstrating the novelty and advancement of the present invention.
惟，以上所述者，僅為本發明之較佳實施例而已，並非用以限定本發明實施之範圍；故在不脫離本發明之精神與範圍下所作之均等變化與修飾，皆應涵蓋於本發明之專利範圍內。 However, the above are only the preferred embodiments of the present invention and are not used to limit the scope of implementation of the present invention; therefore, equal changes and modifications made without departing from the spirit and scope of the present invention should be covered in Within the scope of the patent of the present invention.
