More than 17 million electric cars were sold worldwide in 2024 — over one in every five new cars.
Behind that number is a materials story. Battery pack prices fell by around a fifth in 2024 alone, driven by cheaper cathode chemistries and manufacturing at scale. Every gain in range, charging speed or lifetime traces back to what happens inside electrodes, electrolytes and the interfaces between them.
The next steps — solid-state electrolytes, sodium-ion cells, cobalt-free cathodes, fuel cells for heavy transport — are open materials problems: how ions move through a solid, why interfaces degrade after thousands of cycles, and how to build all of it from abundant elements.
At MSEn you build this knowledge in layers: Physical Chemistry and Inorganic Materials Chemistry in Year 2, then Materials and Systems in Energy Technologies in Year 4, which covers electrodes, electrolytes, batteries, capacitors and fuel cells directly. In Year 5, AI and Machine Learning in Materials Science applies data-driven methods to battery materials.
