Cell Specifications
===================

For a given battery model, we can compute the mass, the capacity and the nominal energy without running any
simulation. A :code:`CellSpecificationSummary` object can be instantiated from a model to print all this information

We setup a model using :code:`runBatteryJson` but with the option :code:`runSimulation` set as false to avoid running the simulation.

.. code:: matlab

   jsonstruct = parseBattmoJson('JsonDataFiles/sample_input.json');
   model = runBatteryJson(jsonstruct, 'runSimulation', false);

   css = CellSpecificationSummary(model);

Then, using the :code:`printSpecifications` method, we get an overview of the cell specifications

.. code:: matlab

   >> css.printSpecifications

There exist separate functions to compute all this information separatly.
               

* :battmo:`computeCellMass` computes the **mass** of the battery and its components
* :battmo:`computeCellCapacity` computes the **capacity** of the the electrodes
* :battmo:`computeCellEnergy` computes the **total energy** of the battery when discharged at equilibrium conditions.
  It means that the transport effects are totally neglicted and corresponds to the case of an infinitly small CRate.
