## Abstract

The present invention relates to a modular lithium-ion battery system that can be scaled vertically and horizontally. A plurality of cell modules can combined to form stacks and layers. Each cell module has a cell body housing a plurality of battery cells. Each cell module has a positive fuse plate and a negative fuse plate connected to opposing sides of the plurality of battery cells.

## Claims

### Claim 1

A modular lithium-ion battery system comprising:
at least one cell module comprising:
a plurality of battery cells;
a cell body formed with a plurality of apertures such that each battery cell of the plurality of battery cells fits into a aperture of the plurality of apertures;
a printed circuit board (PCB);
a positive fuse plate disposed above the cell body such that each battery cell touches the positive fuse plate;
a negative fuse plate disposed below the cell body such that each battery cell touches the negative fuse plate;
a negative terminal rod coupled to PCB, the positive fuse plate, and the negative fuse plate;
a plurality of standoffs separating the PCB and the positive fuse plate.
