What is Study of Molybdenum Disulfide as a Negative Electrode Additive for Stationary Flooded Lead Acid Batteries with Tubular Positive Plates about?

## Abstract Two dimensional layered molybdenum disulfide (MoS~2~) nanosheets possess great potential for lithium‐ion batteries, but their role in lead‐acid batteries (LAB) is not well known and documented. In this work, for the first time, full scale tubular positive flooded lead‐acid battery containing MoS~2~ in negative electrode was compared to control battery containing only carbon black for stationary/float application. Discharge capacity and an endurance test for 2000 h under constant current charging regime were investigated as per the Indian standard for testing stationary LAB (with tubular positive plate) in monobloc container (IS 13369 : 1992, reaffirmed in 2017). Inclusion of MoS~2~ does not negatively impact discharge capacity or endurance performance; instead, it improves these parameters 2–5 % over control battery. A significant drop in charging voltage is observed in the battery containing MoS~2~ throughout 2000 h of endurance testing. A battery containing MoS~2~ passes a similar current of 15 A at 15.2 V as control battery at 15.8 V. Battery containing MoS~2~, therefore, could be recharged at lower voltages than control batteries to reach identical Ah, thus delaying
