DESCRIPTION:Since the invention of the Li ion battery more than 40 years a
 go there have been steady improvements in LIB performance\, such as energy
  and power density. However\, the most dramatic change has been the reduct
 ion by more than an order of magnitude in the cost per unit energy stored 
 due to manufacturing innovations. LIB prices are continuing to reduce\, al
 beit more slowly\, but battery performance is beginning to stagnate\, disa
 ppointingly well-below the intrinsic energy storage performance of the act
 ive cathode and anode materials. The cause of the performance plateau is t
 he ubiquitous method of manufacturing the electrodes\, which although high
 ly productive and cost-effective\, constrains the range of electrode struc
 tures possible - and therefore performance that can be achieved.\n\nThis t
 alk explores how to configure conventional\, widely available energy stora
 ge materials into different structural arrangements and examines if and wh
 y these changes can deliver useful benefits\, and under what conditions be
 nefits might be maximised. The electrochemical response of these deliberat
 ely heterogeneous electrodes is complex and so models are used in conjunct
 ion with experiment to unpick and understand the underlying physical behav
 iour. With this knowledge\, such models are on the cusp of being able to d
 esign rationally electrodes structures that produce an optimised electroch
 emical response against a set of performance requirements. However critica
 l to realising hetero- or smart electrodes in practice are manufacturing a
 pproaches that provide sufficient finesse in microstructural control. Seve
 ral examples will be described including various graded electrodes\, layer
 ed electrodes of two different active materials\, novel binder arrangement
 s\, and interlayers in solid-state batteries.
