The specific energy of LFP batteries is lower than that of other common lithium-ion battery types such as nickel manganese cobalt (NMC) and nickel cobalt aluminum (NCA). As of 2024, the specific energy of CATL's LFP battery is claimed to be 205 watt-hours per kilogram (Wh/kg) on the cell level. [13] BYD's LFP battery specific energy is 150 Wh ...
A typical 12 V, 40 Ah lead-acid car battery. An automotive battery, or car battery, is a rechargeable battery that is used to start a motor vehicle.. Its main purpose is to provide an electric current to the electric-powered starting motor, which in turn starts the chemically-powered internal combustion engine that actually propels the vehicle.
A lantern battery is a rectangular battery, typically an alkaline or zinc–carbon primary battery, used primarily in flashlights or lanterns. Lantern batteries are physically larger and consequently offer higher capacity than the more common flashlight batteries. Lantern batteries comprise multiple cells inside a housing.
A silver oxide battery (IEC code: S) is a primary cell using silver oxide as the cathode material and zinc for the anode. These cells maintain a nearly constant nominal voltage during discharge until fully depleted. [ 2 ]
