Difference Between Lithium and Li-ion Batteries for Digital Cameras.Lithium and alkaline camera batteries are primary batteries and only designed for single use. Primary camera batteries cannot be recharged. Although the average cost-per-use will exceed the cost of rechargeables, they benefit from better single use performance and low self discharge characteristics.

Li-Ion and NiMH camera batteries are considered secondary batteries, which means that it can be recharged with its designated camera battery chargers.
