Electrozi hibrizi cu performanta mixta de energie si putere pentru bateriile litiu-ion de generatie viitoare

Summary

The project is based on a multi-disciplinary approach focused on solving the challenges that have limited Li-ion batteries in EVs. The main objective is to develop Generation 3b Li-ion batteries, which combines high-capacity anode materials with high-voltage cathode materials to store significantly more energy with less weight and volume in a safe electrolyte, manufacturing methods, cell designs, and testing procedure – cell formation (initial cycling) and ageing, to address these challenges in a sustainable way. Ecological and economic sustainability is a key focus of the project. Thus, the project will target the development of environmentally friendly water-based processing of cobalt-free cathode materials. This has the potential to significantly improve the cost and safety of the manufacturing process and reduce dependence on critical raw materials (CRMs). The project concept uses abundant electrode materials like iron, manganese, and silicon, with a net CRM reduction of >85%.

Objectives

The main objective of this project is to develop Generation 3b Li-ion batteries with key performance indicators capable of fast charging, high power discharging, and long cycle life by environmentally and economically sustainable production processes to TRL6. This will be done through:

• Co-free hybrid electrode architectures with improved environmental impact and ecological sustainability;
• electrode scale-up optimization using advanced manufacturing methods;
• definition of protocols for cell formation and test cell performance and ageing as a function of operating temperature, depth of discharge and charging conditions;
• post mortem analysis for deeper understanding in normal fast charging and discharging conditions and the influence of operating temperature;
• evaluation of gas formation and evolution in high voltage Li-ion pouch cells measured by on-line mass spectrometry – effects of C-rate and cell voltage
