Selection of charge methods for lithium ion batteries by considering diffusion induced stress and charge time

摘要: Abstract This article demonstrates the design of charging strategies for lithium ion batteries with considering balance between diffusion induced stress and total charge time two- three-stage methods. For two-stage galvanostatic-potentiostatic method low mechanical can be achieved without increasing by switching galvanostatic to potentiostatic at moment when concentration surface particles reaches limit c ¯ surf = 0 . A method, which consists an initial stage high current, a current ending stage, is suggested. Employing helpful not only in accelerating process, but also controlling once electrical duration are properly designed.
