Abstract

The development of battery materials and pack structures is crucial for enhancing electric vehicle (EV) performance and adoption. This study examines the impact of Ni-rich cathode materials and advanced cell-to-pack (CTP) designs on the energy and environmental sustainability of power batteries. A correlation equation that links energy consumption with curb weight and ambient temperature was established to accurately assess energy consumption during the usage stage of EVs. High-nickel, low-cobalt lithium nickel cobalt manganese oxides (NCM) batteries demonstrated superior life cycle environmental performance, primarily due to the significant environmental impacts of CoSO₄ production. However, the benefits of CTP batteries over traditional cell-to-module (CTM) batteries are minimal. In southern provinces of China, abundant clean energy for electricity generation can reduce the life cycle carbon footprint of power batteries by over 70 % compared with northern provinces, highlighting the importance of transitioning to clean energy sources for sustainable EV industry development.

探索先进锂离子电池技术在能源和环境方面的可持续性

电池材料和电池组结构的开发对于提高电动汽车（EV）的性能和采用率至关重要。本研究探讨了富镍正极材料和先进的电池组（CTP）设计对动力电池的能源和环境可持续性的影响。为了准确评估电动汽车使用阶段的能耗，建立了能耗与整备重量和环境温度之间的相关方程。高镍低钴锂镍钴锰氧化物（NCM）电池表现出卓越的生命周期环境性能，这主要是由于 CoSO4 生产对环境造成了重大影响。然而，与传统的电池到模块（CTM）电池相比，CTP 电池的优势微乎其微。在中国南方省份，丰富的清洁能源发电可使动力电池的生命周期碳足迹比北方省份减少 70% 以上，这凸显了向清洁能源过渡对电动汽车行业可持续发展的重要性。

期刊介绍： The journal Resources, Conservation & Recycling welcomes contributions from research, which consider sustainable management and conservation of resources. The journal prioritizes understanding the transformation processes crucial for transitioning toward more sustainable production and consumption systems. It highlights technological, economic, institutional, and policy aspects related to specific resource management practices such as conservation, recycling, and resource substitution, as well as broader strategies like improving resource productivity and restructuring production and consumption patterns. Contributions may address regional, national, or international scales and can range from individual resources or technologies to entire sectors or systems. Authors are encouraged to explore scientific and methodological issues alongside practical, environmental, and economic implications. However, manuscripts focusing solely on laboratory experiments without discussing their broader implications will not be considered for publication in the journal.
