DESCRIPTION:Portable and stationary rechargeable batteries are within the m
 any energy-related technologies that require fast progress within the urge
 nt need of remediation of global climate. For example\, batteries can stil
 l represent up to a third of electric vehicles emissions due to their manu
 facturing process and lack of end-of-life management. Developing fundament
 ally sustainable battery materials and electrode processing stands as a ce
 ntral strategy for efficient battery recycling. One essential requirement 
 of next-generation battery technologies is the substitution of costly elem
 ents like Li and Co by widely (and more evenly) available ones like Na and
  Fe in the electrode materials. This implies the development of new energy
  storage materials\, as well synthetic methods. Materials with porous and 
 hollow morphologies are one of the promising approaches in achieving long-
 term stability in batteries. Such structures can buffer volumetric changes
  associated with many energy storage mechanisms (like conversion reactions
  or ion insertion)\, avoiding effects like aggregation\, structure collaps
 e and loss of conductivity which leads to poor electrochemical performance
 . Prussian blue (PB\, KFe[Fe(CN)<sub>6</sub>]) and its analogues (PBA\, AM
 [M’(CN)<sub>6</sub>]) are cheap\, easy to synthesize\, non-toxic\, bioco
 mpatible\, water and air-stable metal complexes. They have an intrinsic po
 rous framework structure that allows ion intercalation with very little or
  no strain. Their metal centers are electroactive in both organic and aque
 ous media. Therefore\, this class of materials is ideal for battery electr
 ode applications\, achieving high stability and capacity without the need 
 for complex synthetic routes. The tunability of PB(A) structure and compos
 ition also makes them versatile template materials. Through different deri
 vatization methods\, PB derivatives (PBD) can be prepared. Regardless of t
 he relatively simple structure of PB(A)\, PBDs present an ever-growing num
 ber of compositions that encompass metal oxides\, sulfides\, phosphides\, 
 carbides\, hybrids (among others)\, and an array of morphologies from simp
 le cubes to highly complex hollow and porous structures. Such PBD have rec
 ently demonstrated state of the art performance in catalysis and energy st
 orage applications. This talk will give an overview of the current challen
 ges and strategies to achieve high-performance sustainable batteries\, wit
 h a focus on PB- and PBD-based electrode materials.\nSpeaker: Dr. Samantha
