Abstract
With the rapid promotion of the number of China’s new energy vehicles in promotion and application, it is of great significance to ensure the recycling of the waste power batteries. It can not only effectively reduce the safety and environmental protection risks brought by the waste power battery, but also alleviate China’s dependence on rare metals such as cobalt and lithium, which has been widely concerned by the industry. In this paper, the cost analysis model of waste power battery treated by hydrometallurgical process is established, and the economy of recycling of ternary material battery and LFP battery is compared and analysed, and the overall economy of the whole power battery recycling industry is analysed, and the relevant conclusions are obtained, and the relevant suggestions of recycling of power battery are put forward according to the analysis results, to provide reference for industry and related management departments.
Highlights
The recycling of waste power battery refers to the recycling process of the waste power battery for the purpose of recycling valuable elements in the treatment of dismantling, crushing, smelting and so on[1].At present, China's waste power batteries can be divided into two categories: ternary material batteries and lithium-ion ferrous phosphate batteries (LFP).Considering from the technical level, the two categories of waste power batteries can be safely, environmentally friendly and effectively recycled by adopting the technical route dominated by hydrometallurgy process
In order to facilitate the quantitative analysis of the recycling economy of different types of waste power batteries, this paper establishes a unified mathematical model of the recycling income of waste power batteries according to the cost analysis method and appropriate simplification [2]
The recycling income of waste power battery mainly comes from the recycling of cobalt, nickel, lithium, aluminium, copper and other metals with high recycling value in the power battery
Summary
With the continuous increase of the number of China's new energy vehicles in promotion and application, the following waste power batteries are about to enter the period of large-scale decommissioning. If the waste power batteries cannot be properly recycled, it will bring serious safety risks and environmental pollution to the society, and will cause the loss of precious metals such as cobalt and lithium. The recycling of waste power battery refers to the recycling process of the waste power battery for the purpose of recycling valuable elements in the treatment of dismantling, crushing, smelting and so on[1].At present, China's waste power batteries can be divided into two categories: ternary material batteries and lithium-ion ferrous phosphate batteries (LFP).Considering from the technical level, the two categories of waste power batteries can be safely, environmentally friendly and effectively recycled by adopting the technical route dominated by hydrometallurgy process. The technology is mature, the element recycling rate is high, and mature industrialization experience is gained, and Quzhou. Guangzhou GHTECH and other representative recycling enterprises have emerged
