What is the system boundary of cobalt sulfate production?
The system boundary of this study is described as all activities within the cobalt sulfate production process (Fig. 1). “Cradle-to-gate” LCA research includes all relevant life cycle stages from ore mining to beneficiation, primary extraction, and refining processes.
Do downstream users of cobalt sulfate need a 'cradle-to-gate' life cycle assessment?
This paper builds a comprehensive inventory to support the data needs of downstream users of cobalt sulfate. A “cradle-to-gate” life cycle assessment was conducted to provide theoretical support to stakeholders. A life cycle assessment was performed based on ISO 14040 to evaluate the potential environmental impact and recognize the key processes.
What are the four stages of cobalt sulfate production?
The system boundary of this study contains four stages of cobalt sulfate production: mining, beneficiation, primary extraction, and refining. Except for the experimental data used in the primary extraction stage, all relevant data are actual operating data.
Does cobalt sulfate production affect the environmental burden of refining?
An LCA analysis was conducted on cobalt sulfate production to evaluate the environmental burden of cobalt refining, including mining, beneficiation, primary extraction, and refining phases.
How does cobalt affect lithium-ion battery production?
Research found that cobalt-dependent technologies face a limitation on cobalt supply concentration due to the increased lithium-ion battery demand (Fu et al. 2020). This situation forces global battery manufacturers to seek new cobalt alternative materials or reduce the use of cobalt.

Lithium battery production capacity calculation
To calculate the capacity of a lithium-ion battery pack, follow these steps:Determine the Capacity of Individual Cells: Each 18650 cell has a specific capacity, usually between 2,500mAh (2.5Ah) and 3,500mAh (3.5Ah).Identify the Parallel Configuration: Count the number of cells connected in parallel. For instance, if four cells are connected in parallel, the total capacity is the sum of the individual capacities. [pdf]
