We introduce and critically assess recently proposed strategies for structuring electrode architectures, including spatial gradients of local composition and microstructure; metal-foil current collector alternatives; and electrode templating techniques, evaluating both achievements in battery performance and commercial applicability.
An example of a structural battery has a final composition of 2% carbon black, 11.5% carbon nanofiber, 35% LiCoO 2, and 51.5% PVDF. Fig. 3 compares the stress–strain curves of two structural cathodes to a control sample prepared according to conventional plastic battery fabrication techniques and compositions.
Lithium-ion battery cells are composed of structural constituents spanning over multiple length scales. Figure 1a shows a typical cylindrical LiB scanned by X-ray micro-computed tomography (micro-CT) at a voxel size of 12.9 μm, with a corner-cut-out showing the auxiliary components in the cell cap and the internal structure of the cell.
Another likely cause is the dense structure of the electrode which is based on high molecular weight PVDF. Without the porosity which permeates through common lithium ion batteries allowing ion transport, our structural battery relies on very low porosity and the surface ion conduction provided by the ethylene oxide moieties.
Structural battery composites are one type of lithium-ion batteries that employs carbon fiber as the negative electrode 2. Since carbon fiber is an excellent lightweight structural reinforcement material the structural battery composite inherits high mechanical properties 3.
Its porous structure is formed by polymerization-induced phase separation (PIPS) reaction 14. The solid polymer backbone ensures the integrity of the entire structure, whereas the liquid electrolyte, which occupies the porous network structure, allows the transport of lithium ions.
The structural battery components were made of composites containing high molecular weight poly (vinylindene fluoride) PVDF (Aldrich, Average Mw ca. 534,000) with a process modified from one previously reported .
