MaterialComposition Battery - BatteryChemistry wrong

[BirgitBoss]

BatteryChemistry is probably a Set and not a single entity:

  "BatteryChemistry" : {
    "ShortName" : "NMC",
    "ClearName" : "Lithium nickel manganese cobalt oxides"
  },

it must be

"BatteryChemistry" : [ {
"ShortName" : "NMC",
"ClearName" : "Lithium nickel manganese cobalt oxides"
} ],

MaterialComposition/MaterialChemistry is a SML with SMC with name MaterialChemistry.
Unfortunately, they have the same name.
