车辆用锂二次电池及其制造方法
摘要：
本发明涉及一种车辆用锂二次电池及其制造方法。具体地，本发明涉及一种车辆用锂二次电池包括含锂负电极、设置于负电极上并包含二硫化物聚合物的负电极涂层、设置于负电极涂层上的电解质层和设置于电解质层上的正电极。该二硫化物聚合物具有1,000～10,000,000的分子量。负电极涂层的聚合物负载水平为0.025～0.25mg/cm2。负电极涂层的质量负载水平为1～1,000μg·cm-2。负电极涂层具有小于负电极的厚度。负电极涂层进一步包含无机物质。无机物质包括Al2O3、SiO2、TiO2或它们的混合物中的至少之一。
摘要（英）：

The present invention relates to a lithium secondary battery for a vehicle and the manufacturing method of the same. The lithium secondary battery for vehicles includes a negative electrode includinglithium, a negative electrode coating layer provided on the negative electrode and including a disulfide polymer, an electrolyte layer provided on the negative electrode coating layer, and a positiveelectrode provided on the electrolyte layer. The disulfide polymer has a molecular weight of 1,000 to 10,000,000. A polymer loading level of the negative electrode coating layer is 0.025 to 0.25 mg/cm2. A mass loading level of the negative electrode coating layer is 1 to 1,000 [mu]g.cm-2. The negative electrode coating layer has a thickness smaller than that of the negative electrode. The negativeelectrode coating layer further includes an inorganic substance. The inorganic substance includes at least one of Al2O3, SiO2, TiO2, or mixtures thereof.
