Cell frame set and energy storage device package including cell frame set

A cell frame set for a cell, comprising:

• a first frame having a first side edge of the first frame and a second side edge of the first frame opposite to the first side edge of the first frame, wherein the first side edge of the first frame and the second side edge of the first frame are provided with protruding structures;
• a second frame having a first side edge of the second frame and a second side edge of the second frame opposite to the first side edge of the second frame, wherein the first side edge of the second frame and the second side edge of the second frame are provided with fitting structures;
• at least one intermediate frame disposed between the first frame and the second frame, each of the at least one intermediate frame having a first side edge and a second side edge opposite to the first side edge, wherein the first side edge and the second side edge of the each of the at least one intermediate frame are provided with a protruding structure and a fitting structure corresponding to the protruding structure;
• the protruding structure of one intermediate frame forms a fit with the fitting structure of the second frame, the fitting structure of the one intermediate frame or another intermediate frame forms a fit with the protruding structure of the first frame;
• the first frame further comprises a third side edge of the first frame and a fourth side edge of the first frame opposite to the third side edge of the first frame, the first frame is provided with a first baffle plate at the third side edge of the first frame;
• the first baffle plate comprises a two-layer stepped structure with a support region;
• the cell extends in a first direction from the third side edge of the first frame to the fourth side edge of the first frame;
• the support region supports a cell tab of the cell, wherein the cell tab rests on the support region of the two-stepped layer structure and has a first bend in a second direction perpendicular to the first direction and has a second bend in a third direction opposite to the second direction, such that the bent cell tab forms a U shape;
• and
• the first baffle plate separates bent cell tabs of adjacent layers of cells from each other.

An energy storage device package, comprising:

• a fixing steel strip;
• a package housing;
• and
• a cell frame set for a cell, comprising:
• a first frame having a first side edge of the first frame and a second side edge of the first frame opposite to the first side edge of the first frame, wherein the first side edge of the first frame and the second side edge of the first frame are provided with protruding structures;
• and
• a second frame having a first side edge of the second frame and a second side edge of the second frame opposite to the first side edge of the second frame, wherein the first side edge of the second frame and the second side edge of the second frame are provided with fitting structures,
• wherein,
• the protruding structures of the first frame form a fit with the fitting structures of the second frame;
• the first frame further comprises a third side edge of the first frame and a fourth side edge of the first frame opposite to the third side edge of the first frame, the first frame is provided with a first baffle plate at the third side edge of the first frame;
• the first baffle plate comprises a two-layer stepped structure with a support region;
• the cell frame set is configured to structurally support the cell such that:
• the cell extends in a first direction from the third side edge of the first frame to the fourth side edge of the first frame;
• and
• the support region supports a cell tab of the cell, wherein the cell tab rests on the support region of the two-stepped layer structure and has a first bend in a second direction perpendicular to the first direction and has a second bend in a third direction opposite to the second direction, such that the bent cell tab forms a U shape;
• and
• the first baffle plate separates bent cell tabs of adjacent layers of cells from each other;
• and
• wherein the fixing steel strip surrounds and fixes the cell frame set, and the package housing covers the fixed cell frame set.
