Ustanovljen uzrok samopražnjenja litijum-jonskih baterija: radi se o hemijskoj reakciji između PET trake koja osigurava unutrašnju strukturu baterije i metanola.

Da vam uštedim čitanje članka, ovde su dve zadnje rečenice njegovog zaključka:
"According to the proposed formation mechanism, DMT stems from the LiOMe catalyzed reaction of
methanol with PET. The former can be formed by hydrolysis of DMC with residual water, the latter is found in the tape used to
secure the ends of the jelly roll after winding."
Radi se o značajnom saznanju, pa se očekuje brza modifikacija procesa proizvodnje, odn. zamena PET-a drugim materijalom.
