Do you mean non-rechargeable AA? If so, I think it is not Li-Ion, but it is lithium (Li), there are some differences between them:
1. Li bat is single-use and non-rechargeable, Li-Ion bat is rechargeable
2. Li has 1.5V voltage and Li-Ion has 3.7V voltage
And you can not use Li-ion bats instead of Li bats, in this case you ruin your device
