The company acknowledged in 2015 that its claims regarding its organic batteries have not been scientifically peer-reviewed.{{citation |author=Leo Kelion |title=CES 2015: The charger that boosts battery in seconds |date=January 7, 2015 |url=https://www.bbc.com/news/technology-30708945 |publisher=BBC News}}{{citation |url=https://autos.yahoo.com/news/israeli-firm-says-away-electric-car-battery-charges-172007716.html |author=Stephen Edelstein |title=Israeli Firm Says It's A Year Away From Electric Car Battery That Charges In 3 Minutes |date=January 8, 2015 |website=Motor Authority}}

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.{{citation |url=https://www.themarker.com/technation/1.4444117 |author=Eliran Rubin |date=September 14, 2017 |title=מרצדס מובילה השקעה של 60 מיליון דולר בסטורדוט הישראלית |website=TheMarker}} 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. 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.{{citation |last=Ackerman |first=Gwen |date=June 11, 2019 |title=Electric Scooter Revs Up in Five Minutes with StoreDot Battery |url=https://www.bloomberg.com/news/articles/2019-06-11/electric-scooter-revs-up-in-five-minutes-with-storedot-battery |url-status=live |website=Bloomberg |archive-url=https://web.archive.org/web/20220102041449/https://assets.bwbx.io/s3/readings/PSXQOT6TTDS81561298165764.mp3 |archive-date=January 2, 2022}}{{citation |author=Ryan Browne |date=June 12, 2019 |title=StoreDot and BP Charge an Electric Scooter in just Five Minutes |url=https://www.cnbc.com/2019/06/12/storedot-and-bp-charge-an-electric-scooter-in-just-five-minutes.html |website=CNBC}}

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.{{cite journal |vauthors=Eftekhari A |date=November 2019 |title=Lithium Batteries for Electric Vehicles: From Economy to Research Strategy |journal=ACS Sustainable Chemistry & Engineering |volume=7 |issue=6 |pages=5602–5613 |doi=10.1021/acssuschemeng.8b01494 |s2cid=104468150}} Science journalist John Timmer could not identify in 2021 any published research about the company's germanium battery technology.

The company started promoting its silicon-based batteries in 2019 and ceased development of its germanium-based batteries in 2020. The company sent germanium sample batteries to manufacturers in place of silicon sample batteries.{{citation |author=John Timmer |title=What's the technology behind a five-minute charge battery? |date=January 23, 2021 |url=https://arstechnica.com/science/2021/01/whats-the-technology-behind-a-five-minute-charge-battery/ |publisher=Ars Technica |accessdate=December 21, 2021}} 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.

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.{{citation |url=https://www.powerelectronicsnews.com/silicon-based-anode-for-ev-batteries-ramps-up-energy-density-by-25/ |title=Silicon-Based Anode for EV Batteries Ramps Up Energy Density By 25% |date=December 16, 2021 |author=Maurizio Di Paolo Emilio |website=Power Electronics News}} As of 2023, the company is looking for suppliers capable of manufacturing thousands of tonnes of this material, which is critical for their business.{{citation |url=https://www.youtube.com/watch?v=R3EU5ZKgb_E |title= StoreDot Founder & CEO, Doron Myresdorf |author=The EV Report Podcast |website=YouTube |at=15 minutes and 32 seconds into the video, and 25 minutes and 59 seconds into the video}} 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".{{citation |url=https://www.telegraph.co.uk/cars/hybrid-electric-cars/the-revolutionary-electric-car-battery-technology/ |title= The revolutionary electric car battery technology that you’ve never heard of |author=Vicky Parrott |date=May 21, 2023 |website=The Telegraph}}

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. The company announced in 2023 that its batteries will be commercially available in VinFast vehicles in 2025.

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. StoreDot battery cells require liquid cooling within each cell during fast charging.{{citation |url=https://eepower.com/news/storedot-creates-battery-cooling-for-ev-extreme-fast-charging/# |title=StoreDot Creates Battery Cooling for EV Extreme Fast Charging |author=Jake Hertz |date=January 29, 2024 |website=EEpower}} StoreDot announced their upcoming 2025 batteries charge at a rate that adds 100 miles in 5 minutes 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.{{citation |url=https://www.electrive.com/2024/04/04/storedot-achieves-2000-fast-charging-cycles-with-xfc-cells/ |title=StoreDot achieves 2,000 fast-charging cycles with XFC cells |author=Carla Westerheide |date=April 4, 2024 |work=Electdrive |agency=PR Newswire}}.{{br}}2025 charging rate: {{math|(14kWh/100km)×100mi/5min≈270kW}}{{br}}2026 charging rate: {{math|75kWh×70%/10min{{=}}315kW}}

StoreDot raised over 6 million dollars in an initial investment round, and by the end of 2014 had raised another 42 million dollars. It raised another 62 million dollars by the end of 2017. The company was in negotiations in March 2021 for a SPAC merger at a $3.5 billion valuation.{{citation |last=Hazani |first=Golan |date=March 16, 2021 |title=Fast-charging battery startup StoreDot closing on $3.5 billion SPAC merger |url=https://www.calcalistech.com/ctech/articles/0,7340,L-3899283,00.html |access-date=March 18, 2021 |website=Calcalist}} A further funding round of 70-80 million dollars in 2022 gave it a $1.5 billion valuation.{{Cite web |last=Butcher |first=Mike |date=2022-01-11 |title=Fast-charge EV battery maker StoreDot pulls in $80M led led by Vietnam's VinFast |url=https://techcrunch.com/2022/01/11/fast-charge-ev-battery-maker-storedot-pulls-in-80m-led-led-by-vietnams-vinfast/ |access-date=2023-06-19 |website=TechCrunch |language=en-US}} 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.
