Dutch Innovation Promises Safer, More Efficient EV Batteries
Amsterdam, Wednesday, 2 April 2025.
Dutch researchers have developed nickel-based cathodes that may revolutionize EV battery safety and performance, offering longer driving range and enhanced thermal stability.
Breakthrough in Battery Safety
A research team has made significant strides in developing safer nickel-based cathode materials for electric vehicle batteries. The scientists identified critical charging thresholds across fifteen different materials, establishing that exceeding these levels can lead to dangerous overheating and potential fire risks [1]. To address these safety concerns, the team developed a novel ‘thermal stability index’ that measures material reactions during overheating conditions, marking a crucial step toward safer battery technology [1].
Enhanced Performance Potential
According to Professor Arumugam Manthiram, a leading researcher on the project, ‘Cathodes with high nickel content have the potential to revolutionize the EV market by offering greater range’ [1]. This innovation is particularly significant as nickel is more abundantly available in nature and can achieve higher energy densities, translating to increased driving range for electric vehicles [1]. The research, published in Nature Energy, demonstrates how specific chemical compositions and nickel content levels in cathodes directly influence battery safety and performance [1].
Future Development Path
The research team is currently advancing to the next phase of development, focusing on studying the interaction between the investigated cathodes and the electrolyte - the chemical substance responsible for transporting charge-carrying particles during battery charging and discharging cycles [1]. While significant work remains before nickel-based batteries become practical for widespread implementation [1], this research aligns with the growing trend toward safer and more efficient battery technologies in the evolving electric vehicle market [5].
