The present disclosure relates to graded electrodes for an electric battery cell, and to methods of designing and manufacturing such electrodes. Example embodiments include a method of designing an electrode for an electric battery cell, the electrode comprising a compound mixture of an electrochemically active material, an electrically conductive material and a binding material, the method comprising: applying a model for an electrochemical response of the electric battery cell; and optimising parameters of the model to maximise one or more of an energy density, power density, battery health and thermal response of the electric battery cell.

Electrode structure

Material is incrementally deposited using material directed toward a deposition zone. The scan path of the directed material is controlled according to a path plan derived to reduce derivation from an ideal uniform temperature profile for the deposition during the deposition process. A path plan having angled scan passes that intersect (or overcross one another), for example in a mirrorbox path plan, is preferred.

Control of deposition and other processes

A system for incrementally depositing material includes a delivery system for directing a material toward a deposition zone (), a monitoring system for monitoring a parameter of the deposited (a) material and a processing system () arranged to obtain a monitored value for the parameter, derive a predicted future parameter value for the monitored parameter, compare the predicted value with a reference parameter value for the monitored parameter, and produce a control output based on the comparison of the predicted value with the reference value, the control output being capable of modifying operation of the system. The parameter monitored has the tendency to vary over time (and space), and the processing means ensure that control output is not based upon the difference between an originally monitored parameter value and a reference value but rather between a prediction generated value (accounting for passage of time or spacital difference) and the reference value. This provides for more accurate process control.

A process for producing a metallic tool, mould, die or other body of significant thickness or a coating, the process comprising directing a spray ( ) comprising molten metallic droplets carried by a propelling gas toward an object surface ( ) of a substrate or pattern ( ) so as to build up a metallic deposit or coating comprising the mould, tool, die, body or coating on the object surface ( ) of the substrate or pattern ( ), wherein at one or more predetermined stages during spraying droplets of a relatively large mean size are sprayed and at one or more other stages droplets or a relatively smaller mean size are sprayed.
