1. 1. Tuning electrolyte-electrode interphases for low-temperature Li-ion batteries

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Strukturkemi

   Författare :Robin Xu; [2023]
   Nyckelord :Li-ion batteries; Low temperature;

   Sammanfattning : Lithium ion batteries (LIBs) are crucial for modern electronics and electric vehicles (EV). However,their electrochemical performance is facing challenges at low temperatures (e.g ≤ 0 °C) due to reducedLi+ kinetics and increased charge-transfer resistance. LÄS MER

3. 2. Long term aging and creep exposure for advanced heat resistant alloys : A phase analysis

   Kandidat-uppsats, Uppsala universitet/Institutionen för materialvetenskap; Uppsala universitet/Institutionen för kemi - Ångström

   Författare :Daniel Lundberg; Filip Wilson; Hjalmar Gunnarsson; Leo Sjörén; Robin Xu; Erik Djurberg; [2021]
   Nyckelord :Austenitic stainless steel; ferritic steels; nickel based alloys; creep; ageing; XRD; SEM EDS; LOM;

   Sammanfattning : This project was ordered by Sandvik Materials Technology and was performed by a group of students at Uppsala university. The purpose of the project was to study precipitation behavior and structure stability in six advanced heat resistant alloys. Each sample were subjected to a creep rupture test in 600 or 700°C depending on the alloy type. LÄS MER
