StoreDot is a developer of lithium-ion (Li-ion) batteries for electric vehicles founded in 2012 by Doron Myersdorf, Simon Litsyn, and Gil Rosenman. It is based in Herzliya, Israel.
The company was founded around developing peptide-based mobile phone displays and data storage. The company reported it was ready to commercially release these products: peptide-based displays by 2016; peptide-based batteries for mobile phones that fully charge in 30 seconds by 2016; germanium-based mobile phone batteries by 2019; electric car and aerial drone batteries that fully charge in five minutes by 2020; and scooter batteries that fully charge in under five minutes by 2021. None of the company's products were ever commercially released as of March 2022. [1]
The company, as of 2023, is developing a silicon-based electric vehicle battery which it aims to deliver commercially in 2025, [4] which will be capable of 270kW charging. [5] The company does not plan to become a battery manufacturer or supplier, but instead plans to license its technology to major manufacturers or lease dedicated manufacturing capacity from existing suppliers, [6] saying its silicon batteries can be manufactured using existing factories and manufacturing processes. [7]
StoreDot was founded in 2012 by Doron Myersdorf, Simon Litsyn, and Gil Rosenman, initially developing displays and storage devices based on research by Ehud Gazit. A year later its CEO, Myersdorf, said their peptide-based display technology is ready to be "packed and sold" and its related intellectual property could be sold for 300 million dollars. [8] [9] The displays and storage devices were based on "peptide nanocrystals", and a prototype storage device was made in 2012 that is "three times faster than conventional memory." [10] The company's CEO said the display technology is 20% more power-efficient and 90% less costly to manufacture than OLED, and the displays were ready in 2015 for full-scale manufacturing using existing factories and manufacturing processes, [11] and were to be commercialized by 2016. [12] [13] By 2019 the display technology was spun off into its own company, MolecuLED. As of 2022, MolecuLED has no employees. [1]
StoreDot reported in 2014 to have developed organic-compound peptide-based smartphone batteries capable of being fully charged within 30 seconds. [1] [14] The company said its 30-second-charging organic-compound-based battery would be commercially available for smartphones by 2016, [1] [12] [13] and for electric vehicles [15] and aerial drones [16] by 2020.
The company acknowledged in 2015 that its claims regarding its organic batteries have not been scientifically peer-reviewed. [17] [18]
The company was developing germanium-based batteries by 2017, citing graphite-free batteries and an electric vehicle battery that fully charges in five minutes, expecting "millions of cars" to be equipped with its electric vehicle battery by 2020. [19] [1] The company announced in 2018 that its mobile phone battery would be commercially available by 2019, and that it had plans to build a battery factory in the United States by 2022. [1] In 2019 it announced the commercialization of a 168-cell germanium-tin battery for electric scooters, and stated that its mobile phone products would be commercially available in late 2020 and the scooter battery would be commercially available in 2021. The company's CEO said its electric car battery would have ten times as many cells as the scooter battery, charge fast enough to add 300 miles of range in under five minutes, and have a cooling system; and that its batteries did not degrade. [20] [21]
A 2019 peer-reviewed study concluded that the company's claimed battery capabilities have no basis in published, peer-reviewed literature, and listed its unreleased products. [22] Science journalist John Timmer could not identify in 2021 any published research about the company's germanium battery technology. [23]
The company started promoting its silicon-based batteries in 2019 and ceased development of its germanium-based batteries in 2020. [1] The company sent germanium sample batteries to manufacturers in place of silicon sample batteries. [23] The company's CEO said the germanium batteries were only developed as proof-of-concept, were only meant to be sold in small quantities, and that they were never released because they weren't sufficiently differentiated from the rest of the market. [1]
Group14 Technologies has developed silicon nanoparticles called SCC55 which allow lithium-silicon batteries to charge from 10% to 80% state-of-charge in 10 minutes. StoreDot tested the material for use in their silicon batteries. [24] As of 2023, the company is looking for suppliers capable of manufacturing thousands of tonnes of this material, which is critical for their business. [6] The battery cells have a sponge-like carbon electrode imbued with silicon nanoparticles that react with the lithium ions, keeping the silicon's expansion within the carbon "sponge". [25]
The company announced in November 2021 that it aims to achieve mass-manufacturing in 2024 of its silicon batteries, having pouch-cell samples produced by its manufacturing partner EVE Energy sent to be tested by global car makers. [1] The company announced in 2023 that its batteries will be commercially available in VinFast vehicles in 2025. [4]
The company's upcoming 2025 batteries are projected to have a peak charging rate of 350kW and a service life of 1000 fast-charging cycles. [25] StoreDot announced their upcoming 2025 batteries charge at a rate that adds 100 miles in 5 minues for a vehicle that uses 14kWh per 100 kilometers, which corresponds to a charging rate of 270kW. StoreDot is developing faster-charging cells that charge a 75kWh battery 70% in 10 minutes (from 10% to 80%) which corresponds to a charging rate of 315kW, which it aims to deliver in 2026. [5] StoreDot demonstrated these batteries in a prototype Polestar 5 sedan. The car is expected to be commercially available in 2027 [26] with batteries developed and manufactured by SK On. [27]
StoreDot raised over 6 million dollars in an initial investment round, and by the end of 2014 had raised another 42 million dollars. [10] It raised another 62 million dollars by the end of 2017. [19] The company was in negotiations in March 2021 for a SPAC merger at a $3.5 billion valuation. [28] A further funding round of 70-80 million dollars in 2022 gave it a $1.5 billion valuation. [3] [29] The company plans as of 2023 to raise further capital in 2024 or 2025 in order to build up its silicon nanoparticles supply chain and secure dedicated manufacturing capacity for its batteries from existing manufacturers.

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 that uses one or more electric motors for propulsion. The vehicle can be powered by a collector system, with electricity from extravehicular sources, or can be powered autonomously by a battery or by converting fuel to electricity using a generator or fuel cells. EVs include road and rail vehicles, electric boats and underwater vessels, electric aircraft and electric spacecraft.
A fuel cell vehicle (FCV) or fuel cell electric vehicle (FCEV) is an electric vehicle that uses a fuel cell, sometimes in combination with a small battery or supercapacitor, to power its onboard electric motor. Fuel cells in vehicles generate electricity generally using oxygen from the air and compressed hydrogen. Most fuel cell vehicles are classified as zero-emissions vehicles. As compared with internal combustion vehicles, hydrogen vehicles centralize pollutants at the site of the hydrogen production, where hydrogen is typically derived from reformed natural gas. Transporting and storing hydrogen may also create pollutants. Fuel cells have been used in various kinds of vehicles including forklifts, especially in indoor applications where their clean emissions are important to air quality, and in space applications. Fuel cells are being developed and tested in trucks, buses, boats, ships, motorcycles and bicycles, among other kinds of vehicles.

Electric motorcycles and scooters are plug-in electric vehicles with two or three wheels. Power is supplied by a rechargeable battery that drives one or more electric motors. Electric scooters are distinguished from motorcycles by having a step-through frame, instead of being straddled. Electric bicycles are similar vehicles, distinguished by retaining the ability to be propelled by the rider pedaling in addition to battery propulsion.
A solar car is a solar vehicle for use on public roads or race tracks. Solar vehicles are electric vehicles that use self-contained solar cells to provide full or partial power to the vehicle via sunlight. Solar vehicles typically contain a rechargeable battery to help regulate and store the energy from the solar cells and from regenerative braking. Some solar cars can be plugged into external power sources to supplement the power of sunlight used to charge their 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 exclusively uses chemical energy stored in rechargeable battery packs, with no secondary source of propulsion. BEVs use electric motors and motor controllers instead of internal combustion engines (ICEs) for propulsion. They derive all power from battery packs and thus have no internal combustion engine, fuel cell, or fuel tank. BEVs include – but are not limited to – motorcycles, bicycles, scooters, skateboards, railcars, watercraft, forklifts, buses, trucks, and cars.
The lithium-titanate or lithium-titanium-oxide (LTO) battery is a type of rechargeable battery which has the advantage of being faster to charge than other lithium-ion batteries but the disadvantage is a much lower energy density.
A solid-state battery 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.
A capacitor electric vehicle is a vehicle that uses supercapacitors to store electricity.
