    Master-uppsats, KTH/Kemiteknik

    Författare :Carl Johan Björkman; [2019]
    Nyckelord :Lithium plating; Batteries; Battery monitoring; Battery charging; Battery ageing; Litiumplätering; Batterier; Batteriövervakning; Batteriladdning; Batteriåldring;

    Sammanfattning : With an increasing demand for sustainable transport solutions, there is a demand for electrified vehicles. One way to store energy on board an electrified vehicle is to use a lithium-ion battery (LIB). This battery technology has many advantages, such as being rechargeable and enabling reasonably high power output and capacity. LÄS MER
