Shelf life Anode Electrolyte Cathode Cutoff Nominal 100% SOC by mass by volume ... Low self-discharge nickel–metal hydride battery: 500–1,500 [13] Lithium ...
The energy density (energy/volume) of a new LFP battery as of 2008 was some 14% lower than that of a new LiCoO 2 battery. [45] Since discharge rate is a percentage of battery capacity, a higher rate can be achieved by using a larger battery (more ampere hours) if low-current batteries must be used.
A lithium manganese iron phosphate (LMFP) battery is a lithium-iron phosphate battery (LFP) that includes manganese as a cathode component. As of 2023, multiple companies are readying LMFP batteries for commercial use. [1] Vendors claim that LMFP batteries can be competitive in cost with LFP, while achieving superior performance. [2]
The most notable difference between lithium iron phosphate and lead acid is the fact that the lithium battery capacity shows only a small dependence on the discharge rate. With very high discharge rates, for instance 0.8C, the capacity of the lead acid battery is only 60% of the rated capacity.
Deep-cycle lead–acid systems often use a low-charge warning light or a low-charge power cut-off switch to prevent the type of damage that will shorten the battery's life. [68] Battery life can be extended by storing the batteries at a low temperature, as in a refrigerator or freezer, which slows the side reactions.

Standard battery nomenclature describes portable dry cell batteries that have physical dimensions and electrical characteristics interchangeable between manufacturers. The long history of disposable dry cells means that many manufacturer-specific and national standards were used to designate sizes, long before international standards were reached.
In 2015, researchers in China used porous graphene as the material for a lithium-ion battery anode in order to increase the specific capacity and binding energy between lithium atoms at the anode. The properties of the battery can be tuned by applying strain. The binding energy increases as biaxial strain is applied. [24]
