From the Instituto Tecnológico de la Energía (ITE) we have the objective of facilitating the process of sustainable and efficient energy transition to companies and society.

BATSENS

Strategies to extend lithium battery life based on new materials and cell sensing (BATSENS)

Description

The service life of a battery is affected by external factors such as extreme temperatures, mechanical stress, excess energy during operation, aging and internal degradation processes. These degradative processes are largely associated with different undesired phenomena that take place in the materials that make up the electrochemical cell. From the perspectives of sustainability, economic efficiency and safety, it is necessary to find materials and processes to increase the safety and lifetime of lithium ion (Li-ion) cells.

Objectives

The objective of the BATSENS project is to implement strategies to extend the useful life of lithium batteries by: 1) Development of new and more stable materials, 2) In-cell component sensing and 3) Post-mortem analysis of cells.

The specific objectives of this proposal are as follows:

Development of new materials
New techniques for the synthesis of new generation nickel-rich NMC type cathodes.
Development of polymeric membranes with improved mechanical and thermal stability through the addition of additives.
Development of new sensors for cell monitoring
- Analysis and selection of key parameters to be monitored in cells.
- Development and testing of sensors to monitor cell parameters.
- Integration of the sensor in pouch cells
Post-Mortem Analysis
- Post-Mortem methodology design.
- Analysis and verification of degradation processes in cells
