2. 1. An Experimental and Theoretical Study of the Mass Transport in Lithium-Ion Battery Electrolytes

   Author : Andreas Nyman; Göran Lindbergh; Mårten Behm; Signe Kjelstrup; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Lithium‐ion batteries; Electrolytes; Transport properties; Conductivity; Diffusion coefficients; Transport number; Maxwell-Stefan equation; Simulations; Mathematical analysis; Polarization; Hybrid electric vehicles; Litiumjonbatterier; Aprotiska elektrolyter; Transport egenskaper; Konduktivitet; Diffusion koefficienter; Transporttal; Maxwell-Stefans ekvation; Simuleringar; Matematisk analys; Polarisation; Elhybridfordon; Electrochemistry; Elektrokemi;

   Abstract : 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. READ MORE

4. 2. Diffusive Mass Transport of Ions in Wood

   Author : Reddysuresh Kolavali; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sorption; wood; mass transport; impregnation;

   Abstract : Understanding the conditions that control the mass transfer of various chemicals/ions in wood is of great importance when it is subjected to various processes. Homogeneous impregnation with chemicals/ions, for example, increases the uniformity of the treatments to which the wood is subjected, reduces reaction times and may increase the yield of the final products.

5. 3. Characterisation and modelling of lithium-ion battery electrolytes

   Author : Peter Georén; KTH; []
   Keywords : lithium battery; electrolyte; characterisation; mass transport; stability; modelling; electrochemical; Raman spectroscopy; impedance;

   Abstract : Rechargeable batteries play an important role as energycarriers in our modern society, being present in wirelessdevices for everyday use such as cellular phones, video camerasand laptops, and also in hybrid electric cars. The batterytechnology dominating the market today is the lithium-ion(Li-ion) battery. READ MORE

6. 4. Electrochemical Investigation of the Reaction Mechanism in Lithium-Oxygen Batteries

   Author : Jonas Lindberg; Göran Lindbergh; Ann M. Cornell; Bryan McCloskey; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lithium-Oxygen Batteries; Lithium Mass Transport; Oxygen Solubility; Reaction Rate Law; Reaction Mechanism; Electrode Passivation; Ultramicroelectrodes; Electrochemical Quartz Crystal Microbalance; EQCM; Chemical Engineering; Kemiteknik;

   Abstract : Lithium-oxygen batteries, also known as Lithium-air batteries, could possibly revolutionize energy storage as we know. By letting lithium react with ambient oxygen gas very large theoretical energy densities are possible. READ MORE

7. 5. Thermal Aspects and Electrolyte Mass Transport in Lithium-ion Batteries

   Author : Henrik Lundgren; Göran Lindbgergh; Mårten Behm; Ann Mari Svensson; KTH; []
