We are currently looking for a driven student to join our Mechanical Validation team to work on an exciting thesis project focusing on characterizing pad materials, understanding their thermal and mechanical properties to investigate the impact of mechanical and thermal degradation of the pad on swelling force predictions in Li-ion batteries. The successful candidate will be based in our Västerås R&D Labs and contribute to our mission of creating a greener future.
About the job
Degradation of pad is a critical issue in the performance of Li-ion batteries, which are widely used in portable electronic devices, electric vehicles, and stationary energy storage. The battery components tend to swell during cycling, leading to loss of contact between the electrodes and electrolyte, causing mechanical and thermal stresses. The pad, made of compressible material, uniformly distributes the swelling force and prevents cells from coming into contact. It also impacts the thermal performance of the battery, as its thermal conductivity and specific heat capacity affect heat transfer and temperature distribution. Over time, the thermal properties of the pad can degrade, further impacting performance.
In this proposed project, the aim is to investigate the impact of mechanical and thermal degradation of the pad on swelling force predictions in Li-ion batteries. This project will involve experimental testing of the mechanical and thermal properties of the pad, as well as understanding the impact of mechanical and thermal degradation of pad on the swelling force at end-of-life. To support this investigation, an initial literature review on mechanical and thermal properties of pad as well as the degradation mechanisms and its impact on swelling force will be carried out.
Key responsibilities include but are not limited to:
Conduct an extensive review of the latest publication in the field of pad characterization, degradation mechanisms and its impact on swelling force
Experimental testing (e.g. compression force) of the mechanical and thermal properties of pad materials
Understanding the impact of mechanical and thermal degradation of pad on the swelling force at end-of-life

Northvolt makes green batteries for a blue planet. Affordable cells and high-quality battery systems. All manufactured with a record-low carbon footprint. Purposely built to provide Europe with the opportunity to switch to renewable energy – efficiently and entirely.
To accomplish this, we do things differently. We design, manufacture, and recycle everything under one roof. We even build our own factories. All this is incredibly challenging and requires us to think in unconventional ways. We’re constantly experimenting, learning and adapting to make batteries so great – they will one day make oil history.
Northvolt is growing fast. We’re staffing our international office in Stockholm, our R&D facility, Northvolt Labs, in Västerås, as well as our Gdansk facility for production of battery systems. We're also hiring for our gigafactory Northvolt Ett in Skellefteå, Sweden. We want to work with smart individuals from all disciplines. Strong individuals that truly want to make a positive impact on the future. Those of us already on board share a passion for our mission. We’re prepared to work hard in pursuit of excellence. We enjoy the ride and our main drive is to make a difference for real. As a team, we’re dedicated to thinking new, working hard and having fun.
