Rechargeable lithium metal batteries are secondary lithium metal batteries.They have metallic lithium as a negative electrode.The high specific capacity of lithium metal (3,860 mAh g −1), very low redox potential (−3.040 V versus standard hydrogen electrode) and low density (0.59 g cm −3) make it the ideal negative material for high energy density battery technologies.

An AA-sized alkaline battery might have an effective capacity of 3000 mAh at low drain, but at a load of 1 ampere, which is common for digital cameras, the capacity could be as little as 700 mAh. [12] The voltage of the battery declines steadily during use, so the total usable capacity depends on the cutoff voltage of the application.
A common battery type in cameras and photographic equipment. In Switzerland as of 2008, these batteries accounted for 6% of lithium camera battery sales.

Discharging the battery fully before recharging may be called "deep discharge"; partially discharging then recharging may be called "shallow discharge". A "charge cycle" is not a unit of time; the length of time spent charging or discharging does not affect the number of charge cycles. [1] Each battery is affected differently by charge cycles ...
Memory effect, also known as battery effect, lazy battery effect, or battery memory, is an effect observed in nickel-cadmium rechargeable batteries that causes them to hold less charge. [ 1 ] [ 2 ] It describes the situation in which nickel-cadmium batteries gradually lose their maximum energy capacity if they are repeatedly recharged after ...
Electric cars perform less well in cold weather. Lower ambient temperatures affect an EV’s range, but also how quickly the battery charges and how effective its regenerative braking system works ...
For example, consider a battery with a capacity of 200 Ah at the C 20 rate (C 20 means the 20-hour rate – i.e. the rate that will fully discharge the battery in 20 hours – which in this case is 10 A). If this battery is discharged at 10 A, it will last 20 hours, giving the rated capacity of 200 Ah.
On such a chart the values of specific energy (in W·h/kg) are plotted versus specific power (in W/kg). Both axes are logarithmic , which allows comparing performance of very different devices. Ragone plots can reveal information about gravimetric energy density, but do not convey details about volumetric energy density .
