The lithium-titanate or lithium-titanium-oxide (LTO) battery is a type of rechargeable battery which has the advantage of being faster to charge [4] than other lithium-ion batteries but the disadvantage is a much lower energy density.
Titanate batteries are used in certain Japanese-only versions of Mitsubishi's i-MiEV [5] electric vehicle as well as Honda's EV-neo electric bike and Fit EV. [6] [7] They are also used in the Tosa concept electric bus. [8] Because of the battery's high level of safety and recharge capabilities, LTO batteries are used in car audio applications as well as mobile medical devices. [9]
An LTO battery is also used in the S-Pen that comes with the Samsung Galaxy Note 20 Ultra 5G. [10]
According to a Weatherflow Co. article, [11] the Tempest weather-station device contains a 1300 mAh LTO battery, charged via four solar panels, requiring "at least 4 hours of adequate sunlight every two weeks."
The Combustion Predictive Thermometer is described as using an LTO battery. According to Combustion Inc., this allows it to safely survive temperatures up to 105 °C (221 °F) inside of ovens. [12]
A lithium-titanate battery is a modified lithium-ion battery that uses lithium-titanate nanocrystals, instead of carbon, on the surface of its anode. This gives the anode a surface area of about 100 square meters per gram, compared with 3 square meters per gram for carbon, allowing electrons to enter and leave the anode quickly. Also, the redox potential of Li+ intercalation into titanium oxides is more positive than that of Li+ intercalation into graphite. This leads to fast charging (higher charging current) being much safer in the case of the titanate, than in the case of carbon, since lithium dendrites are less likely to form in the former case. [13] Lithium-titanate cells last for 6000 to 30000 charge cycles; [14] a life cycle of ~1000 cycles before reaching 80% capacity is possible when charged and discharged at 55 °C (131 °F), rather than the standard 25 °C (77 °F). [15]
A disadvantage of lithium-titanate batteries is their lower inherent voltage (2.4 V), which leads to a lower specific energy (about 30–110 Wh/kg [1] ) than conventional lithium-ion battery technologies, which have an inherent voltage of 3.7 V. [16] Some lithium-titanate batteries, however, have an volumetric energy density of up to 177 Wh/L. [1]

The Log9 company is working to introduce its tropicalized-ion battery (TiB) backed by lithium ferro-phosphate (LFP) and lithium-titanium-oxide (LTO) battery chemistries. Unlike LFP and LTO, the more popular NMC (Nickel Manganese Cobalt) chemistry does have the requisite temperature resilience to survive in the warmest conditions such as in India. LTO is not only temperature resilient, but also has a long life. [17]

A technician can easily replace the battery when its capacity eventually deteriorates to an unacceptable level. [31]
The British Rail Class 93 tri-mode locomotives built by Stadler Rail use lithium-titanate batteries to allow the train to run on unelectrified lines. These liquid cooled cells can be charged while under the overhead lines, or from the onboard diesel engine when the full output isn't needed for traction. [32] [33]

[38] Toshiba SCiB batteries are used in a Japan-only version of Mitsubishi's i-MiEV and Minicab MiEV [5] electric vehicles, and Honda uses them in its EV-neo electric bike and Fit EV, which came to market in the summer of 2012. [6] [7] JR Central's N700S Shinkansen uses SCiB batteries to operate at low speed in the event of a disruption to overhead power. [39]
The Toshiba lithium-titanate battery is low voltage (2.3 nominal voltage), with low energy density (between the lead-acid and lithium ion phosphate), but has extreme longevity, charge/discharge capabilities and a wide range operating temperatures.
In 2024, Toshiba specified an expected life of 45,000 cycles at 10C for its "high power" 2.9 Ah SCiB cell, [3] and 20,000 cycles at 3C for its "high energy" 23 Ah cell. [2] At some loss in expected cycle life, these cells can be charged extremely rapidly from 0% to 80% of capacity: in 1 minute (i.e. at 48C) for the 2.9 Ah cell, and in 6 minutes (i.e. at 8C) for the 23 Ah cell. In April 2024, four Siemens Mireo Plus B battery-electric trains were placed into service, powered by Toshiba LTO cells with an expected service life of 15 years. [40]

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 characterized by higher specific energy, higher energy density, higher energy efficiency, a longer cycle life, and a longer calendar life. Also noteworthy is a dramatic improvement in lithium-ion battery properties after their market introduction in 1991: over the following 30 years, their volumetric energy density increased threefold while their cost dropped tenfold. In late 2024 global demand passed 1 Terawatt-hour per year, while production capacity was more than twice that.
A rechargeable battery, storage battery, or secondary cell, is a type of electrical battery which can be charged, discharged into a load, and recharged many times, as opposed to a disposable or primary battery, which is supplied fully charged and discarded after use. It is composed of one or more electrochemical cells. The term "accumulator" is used as it accumulates and stores energy through a reversible electrochemical reaction. Rechargeable batteries are produced in many different shapes and sizes, ranging from button cells to megawatt systems connected to stabilize an electrical distribution network. Several different combinations of electrode materials and electrolytes are used, including lead–acid, zinc–air, nickel–cadmium (NiCd), nickel–metal hydride (NiMH), lithium-ion (Li-ion), lithium iron phosphate (LiFePO4), and lithium-ion polymer.
An electric vehicle (EV) is a vehicle whose propulsion is powered fully or mostly by electricity. EVs include road and rail vehicles, electric boats and underwater vessels, electric aircraft and electric spacecraft.
Vehicle-to-grid (V2G) describes a system in which plug-in electric vehicles (PEVs) sell demand response services to the grid. Demand services are either delivering electricity to the grid or reducing the rate of charge from the grid. Demand services reduce the peaks in demand for grid supply, and hence reduce the probability of disruption from load variations. Vehicle-to-load (V2L) and Vehicle-to-vehicle (V2V) are related, but the AC phase is not synchronised with the grid, so the power is only available to "off-grid" load.
A battery pack is a set of any number of (preferably) identical batteries or individual battery cells. They may be configured in a series, parallel or a mixture of both to deliver the desired voltage and current. The term battery pack is often used in reference to cordless tools, radio-controlled hobby toys, and battery electric vehicles.
Molten-salt batteries are a class of battery that uses molten salts as an electrolyte and offers both a high energy density and a high power density. Traditional non-rechargeable thermal batteries can be stored in their solid state at room temperature for long periods of time before being activated by heating. Rechargeable liquid-metal batteries are used for industrial power backup, special electric vehiclesand for grid energy storage, to balance out intermittent renewable power sources such as solar panels and wind turbines.
The lithium iron phosphate battery or LFP battery is a type of lithium-ion battery using lithium iron phosphate as the cathode material, and a graphitic carbon electrode with a metallic backing as the anode. Because of their low cost, high safety, low toxicity, long cycle life and other factors, LFP batteries are finding a number of roles in vehicle use, utility-scale stationary applications, and backup power. LFP batteries are cobalt-free. As of September 2022, LFP type battery market share for EVs reached 31%, and of that, 68% were from EV makers Tesla and BYD alone. Chinese manufacturers currently hold a near monopoly of LFP battery type production. With patents having started to expire in 2022 and the increased demand for cheaper EV batteries, LFP type production is expected to rise further and surpass lithium nickel manganese cobalt oxides (NMC) type batteries in 2028.
Nanobatteries are fabricated batteries employing technology at the nanoscale, particles that measure less than 100 nanometers or 10−7 meters. These batteries may be nano in size or may use nanotechnology in a macro scale battery. Nanoscale batteries can be combined to function as a macrobattery such as within a nanopore battery.

An electric vehicle battery is a rechargeable battery used to power the electric motors of a battery electric vehicle (BEV) or hybrid electric vehicle (HEV).
A battery electric vehicle (BEV), pure electric vehicle, only-electric vehicle, fully electric vehicle or all-electric vehicle is a type of electric vehicle (EV) that uses electrical energy exclusively from an on-board battery pack to power one or more electric traction motors, on which the vehicle solely relies for propulsion. This definition excludes hybrid electric vehicles, which use internal combustion engines (ICEs) in adjunct to electric motors for propulsion; and fuel cell electric vehicles (FCEVs) and range-extended electric vehicles (REEVs), which consume fuel through a fuel cell or an ICE-driven generator to produce electricity needed for the electric motors. BEVs have no fuel tanks and replenish their energy storage by plugging into a charging station, electrical grid or getting a new battery at a battery swap station, and use motor controllers to modulate the output engine power and torque, thus eliminating the needed for clutches, transmissions and sophisticated engine cooling as seen in conventional ICE vehicles. BEVs include – but are not limited to – all battery-driven electric cars, buses, trucks, forklifts, motorcycles and scooters, bicycles, skateboards, railcars, boat and personal watercraft, although in common usage the term usually refers specifically to passenger cars.
SB LiMotive was a 50:50 joint company of Bosch and Samsung SDI founded in June 2008. The joint venture developed and manufactured lithium-ion batteries for use in hybrid-, plug-in hybrid vehicles and electric vehicles. It was officially ended in September 2012 with both companies focusing on automotive batteries alone.
The Mitsubishi i-MiEV is a five-door electric city car produced in the 2010s by Mitsubishi Motors, and is the electric version of the Mitsubishi i. Rebadged variants of the i-MiEV are also sold by PSA as the Peugeot iOn and Citroën C-Zero, mainly in Europe. The i-MiEV was the world's first modern highway-capable mass production electric car.
A solid-state battery (SSB) is an electrical battery that uses a solid electrolyte for ionic conductions between the electrodes, instead of the liquid or gel polymer electrolytes found in conventional batteries. Solid-state batteries theoretically offer much higher energy density than the typical lithium-ion or lithium polymer batteries.
Sodium-ion batteries (NIBs, SIBs, or Na-ion batteries) are several types of rechargeable batteries, which use sodium ions (Na+) as their charge carriers. In some cases, its working principle and cell construction are similar to those of lithium-ion battery (LIB) types, but it replaces lithium with sodium as the intercalating ion. Sodium belongs to the same group in the periodic table as lithium and thus has similar chemical properties. However, in some cases, such as aqueous batteries, SIBs can be quite different from LIBs.
This is a list of commercially-available battery types summarizing some of their characteristics for ready comparison.
Research in lithium-ion batteries has produced many proposed refinements of lithium-ion batteries. Areas of research interest have focused on improving energy density, safety, rate capability, cycle durability, flexibility, and reducing cost.
An anode-free battery (AFB) is one that is manufactured without an anode. Instead, it creates a metal anode the first time it is charged. The anode is formed from charge carriers supplied by the cathode. As such, before charging, the battery consists of a cathode, current collectors, separator and electrolyte.
