We report a lithium battery using activated carbon on gas diffusion layer (GDL) electrode as host for lithium polysulfide conversion reaction. The cell operates within 2.8 and 2.1 V and delivers a capacity ranging from 400 mAh g-1 at 1C to 150 mAh g-1 at 40C over 100 cycles. These characteristics allow the achievement of high energy and power density, i.e. practically estimated to reach the maximum values of the order of 300 Wh kg-1 and 12 kW kg-1, respectively. These values, exceeding those delivered by the conventional lithium ion batteries, make our battery of sure interest for practical applications.

Abstract
We report a lithium battery using activated carbon on gas diffusion layer (GDL) electrode as host for lithium polysulfide conversion reaction. The cell operates within 2.8 and 2.1 V and delivers a capacity ranging from 400 mAh g-1 at 1C to 150 mAh g-1 at 40C over 100 cycles. These characteristics allow the achievement of high energy and power density, i.e. practically estimated to reach the maximum values of the order of 300 Wh kg-1 and 12 kW kg-1, respectively. These values, exceeding those delivered by the conventional lithium ion batteries, make our battery of sure interest for practical applications.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
