1. An Experimental and Theoretical Study of the Mass Transport in Lithium-Ion Battery Electrolytes
Sammanfattning : Lithium‐ion batteries are particularly suitable as energy storage solutions in high power applications, such as hybrid electric vehicles. It is generally considered that one of the processes that limit the power density for lithium‐ion batteries is the mass transport in the electrolyte. LÄS MER
2. Discrete element modelling of the mechanical behaviour of lithium-ion battery electrode layers
Sammanfattning : Since their introduction in the late 20th century, lithium-ion batteries have become the leading battery technology for portable devices and electric vehicles due to their high energy density and rechargeability. However, the increasing demand for a longer battery life span is hindered by the fading of the battery’s charge capacity over prolonged use. LÄS MER
3. Techno-economic analysis and optimization of electrochemical energy storage solutions
Sammanfattning : The need to integrate the rapidly growing share of variable renewable energy sources in the power sector requires solutions that are capable of mitigating the intermittent nature of these sources. They are expected to constitute the backbone of the electricity generation system in the coming years in order to reach ambitious goals in terms of energy security and reduction of environmental impact.

4. Electrochemical characterization of LiNi1/3Mn1/3Co1/3O2 at different stages of lifetime
Sammanfattning : Li-ion batteries have entered our everyday life first as power sources for small electronics, and recently for electric vehicles and stationary storage applications. As the requirements on the performance and lifetime of Li-ion batteries increase and diversify, it becomes paramount to properly understand their electrochemical performance at single-electrode level, and their evolution over cycling.

5. A scalable furnace technique to grow silicon nanoparticles for high-performance Li-ion battery anodes
Sammanfattning : Lithium-ion batteries are one of the key technologies to address the global climate challenge. Higher battery capacity could also be seen as indirectly influencing the entire value chain. One way to increase capacity is to add silicon to the graphite anode, since silicon can store much more lithium ions than graphite. LÄS MER
