Geely Short Blade Battery promises LFP strengths in a compact package, but it is not yet a fast charging leader

Geely did not reinvent the LFP battery, it repackaged it

Geely’s Short Blade Battery uses lithium iron phosphate chemistry, better known as LFP. That means no cobalt or nickel, better thermal stability and usually a longer cycle life than more expensive NMC batteries, though with lower energy density. Geely stresses that “short blade” refers to the cell shape. The blade style cell is shorter than usual, giving the manufacturer more freedom when arranging the battery pack and tying it into the body structure. Geely describes the system as part of a broader package that includes the GEA electric platform, Cell to Body construction and an 11 in one electric powertrain.

That matters because, in an electric car, the battery is no longer just a separate box under the floor. When the pack becomes part of the vehicle structure, it affects stiffness, space use, weight distribution and crash behaviour. The Geely EX5 shows where this lands in practice. It is 4615 mm long, has a 2750 mm wheelbase and offers a 461 litre boot, placing it among electric SUVs such as the Volkswagen ID.4, BYD Atto 3 and Hyundai Kona Electric.

The numbers: 3500 cycles, lower resistance and better cold weather behaviour

According to Geely’s own technical release, the Short Blade Battery reaches 3500 charging cycles in the company’s tests, which Geely equates to about 1 million kilometres. The same source claims that the shorter shape and lower internal resistance slow internal chemical side reactions and help extend service life.

Geely’s Spanish material adds comparison figures: internal resistance falls by 5.5 per cent, energy density improves by 6.7 per cent, energy retention at low temperature rises by 8.7 per cent and average charging speed increases by 52 per cent. These are manufacturer figures, so they should be read as technical claims, not the final verdict of an independent laboratory.

Cold weather performance is especially interesting. Geely says the Short Blade Battery retains 96.21 per cent of its working capacity at 0 degrees Celsius and more than 90 per cent at minus 30 degrees Celsius. An earlier international Geely release gave a similar comparison: at minus 30 degrees Celsius, the Short Blade Battery retained 90.54 per cent of capacity, while a longer blade battery fell to 78.96 per cent.

Charging is good, but not a new class benchmark

For the Geely E5, the manufacturer gives 11 kW AC charging and DC fast charging of up to 135 kW. According to the Spanish press material, the car charges from 30 to 80 per cent in about 20 minutes. That is perfectly usable in practice, but it does not put Geely among the fastest charging electric cars on sale today.

Here the distinction between cell level and vehicle level matters. In its battery technology release, Geely says long blade batteries of the same capacity need an average of 26 minutes to charge from 10 to 80 per cent, while the Short Blade Battery takes 17 minutes and 4 seconds, with an average charging rate of 2.45C. Official European and British data for the EX5, however, talk about 30 to 80 per cent in about 20 minutes and DC charging of up to 135 kW.

That is not a contradiction. It shows the layers inside battery marketing. A cell can charge one way on a test bench, while a finished car depends on cooling, battery management, the charger, temperature and warranty risk. For buyers, what matters is how the car behaves at a charger, not only the cell’s C rate.

BYD and CATL keep Geely under pressure

Geely’s Short Blade Battery can only be judged properly against its rivals. BYD’s Blade Battery also uses LFP chemistry and a blade shaped cell. BYD’s European material claims a life of more than 5000 charging cycles, an eight year or 250,000 km warranty and no smoke or flames in the nail penetration test. That means Geely’s 3500 cycle claim is strong, but BYD’s marketed life figure is higher.

CATL plays in another league. It does not sell just one car model, but supplies battery technology to many manufacturers. According to CATL, the Shenxing LFP battery allows 4C fast charging, can add up to 400 km of range in 10 minutes and offers more than 700 km of range on a full charge. Reuters also wrote about the Shenxing Plus battery, which CATL positioned as an LFP solution with more than 1000 km of range.

Geely’s advantage is not an outright record. Its edge may come from vertical integration: Geely develops the battery, platform, body integration and electric drive as one system. That can mean cheaper production, better packaging and a simpler model family. But for the technological flagship crown, it still has to face BYD’s cycle life promise and CATL’s ultra fast charging claims.

Safety is the LFP battery’s strongest selling point

Geely pushes the safety message hard. The company describes a separator with high thermal stability and Self Fusing technology intended to limit internal short circuits after external damage. In Geely’s official release, the Short Blade Battery passed an eight needle simultaneous penetration test, a 26 tonne crush test, seawater immersion, underbody scraping, cold testing, a side impact and a fire test without thermal runaway, smoke, ignition or explosion.

The Spanish material separately mentions a six point penetration test, a fire test lasting more than two minutes at 1000 degrees Celsius, 26 tonnes of pressure, immersion in salt water at a depth of 1.2 metres for more than 48 hours and impact tests at 30 to 40 km/h. According to the manufacturer, there was no smoke, fire or explosion.

That still needs a sober reading. These tests sound impressive, but they come from the manufacturer. Independent confidence grows when the car collects Euro NCAP, ANCAP, insurer and real world usage data. At vehicle level, the Geely EX5 at least sends a strong signal, with Geely pointing to five star results from both Euro NCAP and ANCAP.

For European buyers, the car matters more than the cell

In Europe, the Geely EX5 uses an LFP battery with 60.22 kWh of usable capacity, 11 kW AC charging and DC fast charging of up to 135 kW. According to Geely UK, the EX5 offers up to 267 miles, or about 430 km, of range, charges from 30 to 80 per cent in about 20 minutes and supports V2L and V2V functions.

Those figures place the car in the practical middle class rather than at the technological peak of premium electric cars. A WLTP range of around 430 km suits daily use. A 20 minute charge from 30 to 80 per cent works for longer trips. But the Hyundai Ioniq 5, Kia EV6, Porsche Macan Electric and newer high end CATL applications can be clearly faster at the charger. Geely has to win through price, equipment, warranty and trust in reliability.

The key detail: 30 to 80 per cent is not the same as 10 to 80 per cent

Geely’s message needs careful reading because of the charging window it uses. Many rivals advertise 10 to 80 per cent charging times, because that better reflects a typical long distance charging stop. For the EX5, the Spanish material talks about 30 to 80 per cent, which leaves out the slowest and most temperature sensitive part of the charging curve.

At cell level, Geely does use a 10 to 80 per cent comparison in its battery technology release, but in consumer data for the production car, the focus sits on 30 to 80 per cent. That does not make the battery bad. It simply needs to be said. Otherwise, readers may think Geely is competing directly with 18 minute or 10 minute ultra fast charging promises, when the finished EX5 is not quite in that zone.

Geely is chasing a sensible electric car, not a laboratory record

The Short Blade Battery shows where the Chinese electric car industry is heading. The focus is no longer only on the largest battery and the longest official range. Manufacturers are searching for a combination of lower cost, sufficient charging speed, long life, safe chemistry and good packaging.

For Geely, that is strategically important. In Europe, the EX5 must compete not only with the BYD Atto 3, Volkswagen ID.4 and Hyundai Kona Electric, but also with a consumer prejudice: can a Chinese brand offer long term quality, warranty support and strong resale value? The battery’s 3500 cycle and 1 million kilometre claim helps build that story, but real usage data will convince buyers more than any press release.

Technical summary

Geely Short Blade Battery uses LFP chemistry and a shorter blade shaped cell to improve packaging and Cell to Body integration.

Geely claims up to 3500 charging cycles, which the company equates to about 1 million kilometres.

According to the manufacturer, internal resistance falls by 5.5 per cent, energy density improves by 6.7 per cent and average charging speed rises by 52 per cent.

The Geely EX5 supports 11 kW AC charging and DC fast charging of up to 135 kW, with 30 to 80 per cent taking about 20 minutes.

Against CATL and, in some areas, BYD, Geely does not lead on charging records, but it offers a strong overall package built around safety, durability and space efficiency.
