Energy Storage & Batteries

EAG is active in the energy storage field, particularly in regards to Li ion batteries and fuel cell analysis. In both cases, our scientists provide detailed information on raw materials, such as composition, purity and crystallinity. Furthermore, we can provide information on battery and fuel cell materials after use, examining changes in phase, chemical state, composition and contaminant levels and content after cycling. EAG has the facilities to prepare and analyze materials under inert dry atmospheres.

Lithium ion batteries are used in a wide range of today’s mobile devices due their light weight and high charge density. In recent years, there have been significant technological advances, driven mainly to support electrification of vehicles, which require high power and energy with exceptional safety standards.

To achieve these goals, it is essential have a good understanding of electrochemical processes that occur when batteries undergo a charge/discharge cycle. In addition the quality of the raw materials used for battery manufacturing needs to be carefully controlled to ensure consistent and predictable performance.

EAG applies advanced techniques to address the complex factors that can affect battery or fuel cell performance and cycle lifetime, and the changes that can occur to cell components, such as chemical state and structure during use.

How do we increase battery performance and safety? How do I assess the impact of materials purity on battery performance? Turn to EAG. WE KNOW HOW.

EAG applies advanced techniques to address the factors affecting energy storage, battery performance, cycle life, chemical state and electrochemical processes that occur during use.
