Design and optimization of plastic/composite materials for batteries

It is important to choose compatible polymers that can withstand metal salt solutions or strong acids/bases depending on the battery system. We can help in this process by advising and testing polymer compatibility under a range of conditions.

Purpose

Future battery systems require new combinations of materials and with that come material choices that can optimize efficiency and lifetime.

Method

Literature studies, industrial surveys, and compatibility studies can be performed by us in order to help design the desired battery system with components that provide the best performance over time.

Deliveries

The results are usually delivered to the customer in report form.

Mechanical testing of battery components

In mechanical testing of battery components and battery cases, we test the effect of mechanical impact to ensure that the design is suitable for its application.

Determination of elements in battery materials

Determination of the content of a large number of elements in battery materials including electrolyte, electrodes and separators and casing is performed with screening techniques such as semi-quantitative ICP / MS or with specialized measurements with very small measurement uncertainty.

Water content determination in battery electrolytes

Water is an impurity in Li-ion electrolytes. This is because water reacts, breaks down, important components such as the active salt LiPF6. Control of production and recycling processes towards low water levels is of great importance. We offer analysis of water content in, among other things, ketone-based electrolytes.

Battery testing - Performance and aging test on Li-ion battery cells

We offer electrical cycling of battery cells and modules in different operating temperatures and charging / discharging processes. We have access to a large number of test channels, which means that we can perform the test processes on up to 180 battery cells and 32 battery modules at the same time. We can also perform testing on battery packs.

Thermal runaway in battery cells

Thermal runaway is a stage of rapid self-heating of the battery cell that in the worst case can result in a fire or explosion. Abuse testing of batteries causes thermal runaway and is tested for product development purposes or product approvals in an open or closed reactor.

RISE participation in Battery Sweden

Battery Sweden (BASE) is a center funded by Vinnova from 2020-2030 and headed by Uppsala University. RISE activities within BASE, including scale-up, production, solid-state Li-battery processes and manufacturing technology.

Battery swap system for work machines

For electrification of work machines, the big question is how the machines will have access to electrical energy. Other technology is available to a large extent and can be applied in the machines. This project will develop and demonstrate how a modular battery replacement system is an enabler for electric work machines in different industries.
