A Li - ion battery with a holey graphene catalyst exhibited high rechargeability and superior long - term cycling stability over 200 cycles at ambient temperature . Previously , the electrochemical reaction between carbon with the Lithium catalyst led to problems of producing Li2CO3 , making the battery less rechargeable .
A lithium-CO2 battery with a holey graphene catalyst exhibited high rechargeability and superior long-term cycling stability over 200 cycles at ambient temperature. Previously, the electrochemical reaction between CO2 with the Lithium anode led to formation of insulating Li2CO3, making the battery less rechargeable.
