The “better graphene battery” in this headline was a 2016 announcement about Grabat, a proposed graphene polymer battery from Spain’s Graphenano—not a newly verified breakthrough. Graphenano claimed tests exceeded 1,000 Wh/kg, but the available record does not establish that figure as independently verified performance for a commercial battery cell. The company was still describing its plant as under commissioning in 2018, and its current certificates page does not list battery product certification.
What was the Grabat graphene battery?
Futurism’s July 27, 2016 story reported that Graphenano had introduced a graphene polymer battery called Grabat. It relayed the company’s claims of up to 1,000 Wh/kg, a voltage of 2.3 V, and rapid charging and discharging, as well as possible uses in vehicles, homes, bicycles, drones, and pacemakers. Those were reported claims and proposed applications, not demonstrated specifications for a widely available consumer product.
Graphenano’s February 2016 release described the units as prototypes and said a production center in Yecla was being prepared. It reported tests exceeding 1,000 Wh/kg and discussed potential applications and partners. The release is a company statement reproduced in a third-party archive, not a complete independent test record. The figure is best described as 1,000 Wh/kg claimed — Graphenano/Grabat Energy, 2016.
The 2016 story also forecast prototypes by midyear and commercial production by year-end. Those were forward-looking expectations, not proof that production or retail sales followed on that schedule.

Was the 1,000 Wh/kg claim independently verified?
The reviewed sources do not establish 1,000 Wh/kg as an independently verified commercial-cell result. Energy density is meaningful only when the measurement scope is clear: a material-level or partial-component measurement is not interchangeable with the energy density of a complete battery cell or pack. The available reporting does not provide enough information to treat the claim as a comparable, certified cell specification.
In a contemporaneous investigation, Spanish newspaper El Confidencial reported that TÜV Rheinland characterized material shown by Grabat as a page from a technical test report, rather than a complete independent certificate, and that it had no matching record in its database. That is the newspaper’s account of TÜV Rheinland’s response; the underlying complete test file is not established by the reviewed sources. It is therefore more precise to say the reported document was not a product certificate than to claim that a full test definitively proved or disproved the battery’s performance.

What happened after the announcement?
Graphenano’s own 2018 press release said the Yecla plant was still being commissioned. It described ongoing cell testing and said the product would reach the market after the plant became fully operational and product certifications were completed. This later company statement shows why the 2016 forecast should not be presented as confirmed commercial production. It does not independently verify the battery’s performance.
Graphenano’s current certificates page lists certifications for concrete and mortar admixtures, management, and dental products, but does not list a battery product certification. That page is limited evidence: its silence does not prove that no battery research exists or that no other certification has ever been issued.

A 2017 Graphene Flagship technology roadmap listed a Grabat-related battery manufacturing item as a development to monitor. That is historical context, not independent confirmation of the advertised specifications or proof that the product entered the market.
Are graphene batteries real, and can they beat lithium-ion?
Graphene-related battery research is real, but that broad fact does not validate every product described as a “graphene battery.” The Grabat announcement concerned a particular proposed product, and its headline performance claims remain distinct from independently established results for a commercial cell.

Whether a battery outperforms lithium-ion depends on what is measured and under which conditions. A meaningful comparison would need the same scope and clear data on cell-level energy density, charge and discharge rates, cycle life, safety testing, and certification. The reviewed sources do not provide a like-for-like test of Grabat against a lithium-ion battery, so they cannot support a claim that it was better overall.
How to evaluate a graphene-battery claim
- Check the measurement boundary. Ask whether the number describes an active material, electrode, complete cell, or pack. These are not interchangeable.
- Look for the full test record. A report page or company summary is not the same as a complete independent test report or a product certification.
- Check the test conditions. Energy density alone does not reveal charge speed, cycle life, safety, or performance under practical operating conditions.
- Confirm commercial status separately. A prototype, a plant under commissioning, and a certified product available to buy are different milestones.
- Require a direct comparison. “Better” needs a named comparator and matched test methods; a headline figure by itself is not enough.
Can you buy the Grabat battery today?
The reviewed sources do not substantiate Grabat as a current consumer product suitable for purchase or recommendation. The 2018 company statement described production and certification as unfinished at that time, while the current certificates page reviewed does not list battery product certification. Those facts do not resolve every possible later research or commercial activity, but they are not evidence of an available, certified retail battery.
