Accessing Battery database through PyMatgen

Materials Project Materials Project Data/API

There are currently no pymatgen MPRester methods to retrieve battery information, but there is an API endpoint to retrieve such information by chemical formula or battery ID. Here is a way to add such a method in your code:

from pymatgen import MPRester

def get_battery_data(self, formula_or_batt_id):
    """Returns batteries from a batt id or formula.

    Examples:
        get_battery("mp-300585433")
        get_battery("LiFePO4")
    """
    return mpr._make_request('/battery/%s' % formula_or_batt_id)

MPRester.get_battery_data = get_battery_data

After setting this, you may e.g.

mpr = MPRester()
results_battid = mpr.get_battery_data("mp-300585433")
results_formula = mpr.get_battery_data("LiFePO4")

Eventually, we will include such functionality in a pymatgen release but I hope this helps for now.
