The iPhone is a line of smartphones produced by Apple that use Apple's own iOS mobile operating system. The first-generation iPhone was announced by then–Apple CEO Steve Jobs on January 9, 2007. Since then, Apple has annually released new iPhone models and iOS updates. As of November 1, 2018, more than 2.2 billion iPhones had been sold.
Nominal cell voltage. 3.6 / 3.7 / 3.8 / 3.85 V, LiFePO4 3.2 V, Li4Ti5O12 2.3 V. A lithium-ion or Li-ion battery is a type of rechargeable battery that uses the reversible intercalation of Li + ions into electronically conducting solids to store energy. In comparison with other commercial rechargeable batteries, Li-ion batteries are ...
3LR12 (4.5-volt), D, C, AA, AAA, AAAA (1.5-volt), A23 (12-volt), PP3 (9-volt), CR2032 (3-volt), and LR44 (1.5-volt) batteries. This is a list of the sizes, shapes, and general characteristics of some common primary and secondary battery types in household, automotive and light industrial use. The complete nomenclature for a battery specifies ...

LiFePO4 is a natural mineral of the olivine family (triphylite). Arumugam Manthiram and John B. Goodenough first identified the polyanion class of cathode materials for lithium ion batteries. LiFePO4 was then identified as a cathode material belonging to the polyanion class for use in batteries in 1996 by Padhi et al. Reversible extraction of lithi...
Cell voltageVolumetric energy density = 220 Wh/L(790 kJ/L)Gravimetric energy density > 90 Wh/kg (> 320 J/g). Up to 160 Wh/kg (580 J/g). Latest version announced in end of 2023, early 2024 made significant improvements in energy density from 180 up to 205...Cycle life from 2,700 to more than 10,000 cycles depending on conditions.Next gen high energy density versions have reduced charging lifecycles probably around 5000 max cycles.The LFP battery uses a lithium-ion-derived chemistry and shares many advantages and disadvantages with other lithium-ion battery chemistries. However, there are significant differences.
Home energy storage
Enphase pioneered LFP along with SunFusion Energy Systems LifePO4 Ultra-Safe ECHO 2.0 and Guardian E2.0 home or business energy storage batteries for reasons of cost and fire safety, although the market remains split among competing chemistries. Though lower energy density compared to other lithium chemistries adds mass and volume, both may be more tolerable in a static application. In 2021, there were several suppliers to the home end user market, including SonnenBatterie and Enphase. Tesla...
Vehicles
Higher discharge rates needed for acceleration, lower weight and longer life makes this battery type ideal for forklifts, bicycles and electric cars. 12 V LiFePO4batteries are also gaining popularity as a second (house) battery for a caravan, motor-home or boat. Tesla Motors uses LFP batteries in all standard-range Models 3 and Y made after October 2021 except for standard-range vehicles made with 4680 cells starting in 2022, which use an NMCchemistry. As of September 2022, LFP batteries had...
Solar-powered lighting systems
Single "14500" (AA battery–sized) LFP cells are now used in some solar-powered landscape lighting instead of 1.2 V NiCd/NiMH.[citation needed] LFP's higher[clarification needed] (3.2 V) working voltage lets a single cell drive an LED without circuitry to step up the voltage. Its increased tolerance to modest overcharging (compared to other Li cell types) means that LiFePO4can be connected to photovoltaic cells without circuitry to halt the recharge cycle. By 2013, better solar-charged passive...
