Zašto baterija stari: kemija, toplina i trošak zamjene

Film objašnjava zašto litij-ionska baterija s godinama postaje manje sposobna za isporuku vršne struje – kroz nastanak SEI sloja na grafitnoj anodi, gubitak litijevog inventara i utjecaj temperature na brzinu degradacije. Na konkretnim slučajevima – Appleovom usporavanju iPhonea u prosincu 2017., tužbama vlasnika Nissana Leafa iz 2012. i baterijskom sustavu Hornsdale – prikazuje tko snosi trošak tog kemijskog procesa i gdje trenutačno staju granice znanja.
