There is widespread recognition that the use of energy in the twenty-first century must be sustainable. Because of its extraordinary flexibility, silica sol–gel chemistry offers the opportunity to create the novel materials and architectures which can lead to significant advances in renewable energy and energy storage technologies.
Although materials used in electrochemical devices for energy applications would benefit from the precise structural control that can be achieved by using silica sol–gel chemistry, such synthetic approaches typically result in insulating porous materials.
Here we present a simple, yet highly versatile silica sol–gel process built around a multifunctional sol–gel precursor that is derived from the following: amino acids, hydroxy acids or peptides; a silicon alkoxide; and a metal acetate.
The sol–gel process is widely used for the synthesis of battery electrode materials. The application of sol–gel synthesis to the most common electrode materials for lithium-ion batteries was reviewed in the literature [50, 51]. The ability to fabricate high voltage oxides is particularly important for increased energy densities.
