Following during development of electric vehicles and other modern-life appliances, numerous lithium-ion batteries are fabricated and used every year, and their consumption is constantly expanding. However, the battery life of the lithium-ion batteries is about 3 to 5 years, and there are some hazardous and noxious substances in spent lithium-ion batteries. Therefore, it is necessary to recycling these spent batteries with some resourceful and environment friendly technology. In this work, we propose a novel technology of resourceful disposing and utilizing oxide cathode materials from spent power lithium-ion batteries, which is using the recovered compounds from spent lithium-ion batteries to capture carbon dioxide from fossil fuel plant. The detailed technical routes of laboratory scale test and bench scale test are also given in the work.

Voltage Attenuation

Li-rich layered oxide cathode materials have become one of the most promising cathode materials for high specific energy lithium-ion batteries owning to its high theoretical specific capacity, low cost, high operating voltage and environmental friendliness. Yet they suffer from severe capacity and voltage attenuation during prolong cycling, which blocks their commercial application. To clarify these causes, we synthesize Li1.5Mn0.55Ni0.4Co0.05O2.5 (Li1.2Mn0.44Ni0.32Co0.04O2) with high-nickel-content cathode material by a solid-sate complexation method, and it manifests a lot slower capacity and voltage attenuation during prolong cycling compared to Li1.5Mn0.66Ni0.17Co0.17O2.5 (Li1.2Mn0.54Ni0.13Co0.13O2) and Li1.5Mn0.65Ni0.25Co0.1O2.5 (Li1.2Mn0.52Ni0.2Co0.08O2) cathode materials. The capacity retention at 1 C after 100 cycles reaches to 87.5% and the voltage attenuation after 100 cycles is only 0.460 V. Combining X-ray diffraction (XRD), scanning electron microscope (SEM), and transmission electron microscopy (TEM), it indicates that increasing the nickel content not only stabilizes the structure but also alleviates the attenuation of capacity and voltage. Therefore, it provides a new idea for designing of Li-rich layered oxide cathode materials that suppress voltage and capacity attenuation.
