"Lithium ion batteries are considered as the most potential candidates for energy storage devices"
A native speaker who reviewed this sentence asked me to change "potential" to "promising". I couldn't get it because I can see in oxford dictionary that "potential" is also used as an adjective like in the following examples:
**Many supermarkets now provide free buses to carry potential customers into their premises.’
‘Instead the study was just a process to find out the potential capacity for new homes.’**
Is the change requested by him valid? Can anyone explain please?
