正鎳化合物
英文
nickelous compound-
The preparation and electrochemical performance of nickel hydroxide as a positive active material for the high capacity mh / ni alkaline rechargeable batteries were studied. the research result in this paper has some significance for the further development of nickel electrode with good properties
本文對鎳氫( mh / ni )堿性二次電池中所普遍使用的正極活性物質ni ( oh ) _ 2的制備和電化學行為進行了研究,對于進一步研製和開發綜合性能優良的鎳電極具有一定的實際意義。This thesis focuses on the study of the layered lithium nickel - based oxides as catho de materials lithium - ion batteries, the main aspects follow : 1 study on the synthesis and properties of linixco1 - xo2 by the sol - gel method compared with solid - state method, sol - gel method enjoys the advantage of lower calcining temperature and small uniform particle size of products. after the xrd measurement, it was shown that the single - phase layered compound can be prepared in sintering temperature of 750 for 6 ~ 8 hours. the sintering temperature, the properties and the amounts of doping materials can all affect the product ' s phase, and its structure ( lattice parameter, crystal phase distance )
本論文的研究工作主要集中在作為鋰離子電池正極材料的層狀鋰鎳基氧化物上,包括以下幾個方面: 1溶膠凝膠法( sol - gel )合成lini _ xco _ ( 1 - x ) o _ 2的研究與固相合成法相比,溶膠凝膠法合成lini _ xco _ ( 1 - x ) o _ 2煅燒溫度低,產物顆粒均勻一致,經過xrd的測試過后,結果表明750下燒結6 8小時,即可得到單相產物;燒結溫度,摻雜劑的種類及摻雜劑量均對產物物相的形成產生影響,並對產物的結構產生影響。It has discovered for the first time that the precursor b - ni1 - xcox ( oh ) 2, with pluffy and dendritic morphology, high specific surface area and low tap density, is the best starting material to produce lini1 - xcoxo2 materials, but not the presently thought that high density and spherical particle of ni ( oh ) 2 is fitting for the preparation of ni - cathode materials. using our own precursor can greatly reduce the degree of cation mixing ; improve the electrochemical properties of the aimed materials
發現表面蓬鬆、比表面積高和密度低、呈枝晶狀排列的- ni _ ( 1 - x ) co _ x ( oh ) _ 2前驅體具有較高的化學活性,制得的目標材料可有效抑制陽離子混排產物的生成,而非目前廣泛認為的高密度球形ni ( oh ) _ 2適合作鎳系正極材料的前驅體。
