Electrochemical performance of a tin electrodeposit with a multi-layered structure for Li-ion batteries ABSTRACT The electrochemical performance of a tin electrode synthesized on copper foil by electrodeposition in a pyrophosphate-based bath is examined by modifying its morphology via controlling the cathodic current density. As this current density increases, the morphology of the tin electrodeposit changes from a smooth and compact structure to a microscopically multi-layered structure with open spaces between adjacent layers. The porosity of the multi-layered tin electrode is more than 60% of its volume. The cycle performance and coulombic efficiency of the multi-layered tin electrode are higher than those of the smooth tin electrode, primarily due to the buffering effects of the open spaces between the layers against the volume expansion of the tin anode during cycling. 嗯,就是上面這一堆了! |

鋰電池多層結(jié)構(gòu)鍍錫的電化學(xué)性能研究 摘要: 在焦磷酸為基質(zhì)的鍍錫銅葉構(gòu)成的電極可以通過(guò)控制印機(jī)電路密度來(lái)改變其形態(tài),進(jìn)而檢驗(yàn)其的電化學(xué)性能。隨著電路密度的增加,鍍錫電極的邢臺(tái)從平面、壓縮狀態(tài),變成了精細(xì)的多層結(jié)構(gòu),并且再起相鄰的層與層之間具有開(kāi)放的空間。這種多層結(jié)構(gòu)的電極的孔洞體膨脹要比其體積多出60%。多層結(jié)構(gòu)循環(huán)特性和庫(kù)倫效率要比那些平面狀態(tài)的高,這主要是由于多層結(jié)構(gòu)的層空間存在的緩沖效應(yīng)克服了循化過(guò)程中錫陽(yáng)電極的體膨脹。 |
