Degradation diagnosis of aged Li sub(4)Ti sub(5)O sub(12)/LiFePO sub(4) batteries

Li sub(4)Ti sub(5)O sub(12)/LiFePO sub(4) cells are cycled under 4 different conditions of discharge profile (galvanostatic or driving-based) and cycling rates (C/8 or 1C) during 4-5 months. All the cells exhibit capacity fade whose extent is not correlated with the aging condition. In order to unde...
