Abstract: A module battery having high thermal insulating performance during standby and being easy to manufacture is provided. In a module battery container including: a box for containing a plurality of cells each being a high-temperature secondary cell; and a lid for occluding an opening of the box, the box and the lid each have an atmospheric thermal insulating structure including: an inner container and an outer container each including a metal plate and having a cuboid shape; and a thermal insulating material loaded between the inner container and the outer container, and, in each of the box and the lid, the inner container and the outer container are not in contact with each other, and the thermal insulating material is exposed only at an open end.

Abstract: The invention relates to a process for manufacturing a multilayered porous transport layer, the process comprising (a) providing a first feedstock comprising first metal particles and a first polymer binder; and providing a second feedstock comprising second metal particles and a second polymer binder; the first and the second feedstock having a metal powder content of 40 to 70% by volume; and the first feedstock having (i) metal particles with a smaller average particles size, (ii) a higher metal powder content, or (iii) both, metal particles with a smaller average particles size and a higher metal powder content compared to the second feedstock; (b) coextruding the first and the second feedstock to form a film-shaped green body comprising a first layer and a second layer, the second layer being materially connected to the first layer above the melting temperature and or glass transition temperature of the first polymer binder and the second polymer binder; (c) optionally smoothening the film-shaped green body by rolling or calendering; (d) debinding the film-shaped green body to form a brown body; (e) sintering the brown body under a non-oxidative atmosphere or vacuum and a temperature of from 700 to 1300° C. to form the porous transport layer; wherein the first feedstock and the second feedstock are free of any solvents.
