Battery knowledge · Lithium-ion chemistries and cell formats
Blade cell
A very long, thin prismatic LFP cell, close to a metre in length, laid side by side so the cells themselves stiffen the pack. The format trades cell-level energy density for pack-level packing efficiency and a large cooling surface.
Example
Lithium-ion chemistries and cell formats: an example situation
Two cylindrical cells can share dimensions yet differ in cathode, capacity and current limits.
Read Blade cell alongside Cell-to-pack in this context. Building the pack directly from cells without the intermediate module, using large-format cells that bear load themselves. It raises the cell-to-pack ratio and cuts parts, at the cost of making the pack harder to service.
Use in Lemonergy
Separate chemistry from form factor.
This is a reference concept. No executable Lemonergy block has been verified for this term.
