BYD’s Blade battery technology has revolutionized electric vehicle manufacturing by making it possible to shrink battery packs while increasing driving range, prompting many EV manufacturers to adopt this groundbreaking innovation.
CarNewsChina recently received information from an inside source claiming BYD will release an enhanced Blade Battery model in 2025 with increased energy density and lower production costs.
1. Cell Geometry
BYD’s blade battery has become synonymous with green transportation due to its unique format: installed into a chassis at right angles to it and shaped like a blade, its unique configuration has resulted in an increase of 50% in volumetric energy density.
Lithium iron phosphate provides greater thermal stability and is substantially cobalt-free, while being extremely durable enough to withstand crushing, bending, and heating up to 300 degrees Celsius.
Sources have hinted that BYD’s subsidiary Findreams’ second-generation blade battery, expected to be launched this year, will feature increased energy density of 15% over its predecessor – coming closer to 190 Wh/kg and further enhancing pure electric car driving ranges while helping alleviate concerns over safety accidents as the EV market expands.
2. Cell Weight
BYD’s persistent efforts in battery development over 27 years have produced its innovative Blade Battery. This groundbreaking technology address concerns over electric vehicle safety while offering impressive energy efficiency and strength.
Warren Buffett-backed EV manufacturer Blade Battery’s latest generation has recently undergone rigorous strength tests, such as nail penetration. This innovation could prove revolutionary for power battery safety and accelerate global EV adoption rates.
BYD subsidiary Findreams is developing a second-generation battery with higher energy density – up to 160 Wh/kg, according to CarNewsChina. According to sources close to Findreams’ project, pricing will likely remain similar and shorter blades are expected; charging should take 16C charge rate with 8C discharge and less resistance is also anticipated.
3. Cell Temperature
BYD’s Blade Battery is an LFP battery developed in-house. It derives its name from its physical design which eliminates module layout in favor of improving space utilization by optimizing cell-to-pack architecture; as a result, volumetric energy density has increased by 50% compared to prismatic batteries.
The Blade Battery has proven so strong and resilient that it has passed several rigorous strength tests, including nail penetration and being run over by a 46-ton heavy truck – setting the bar for power battery safety. Therefore, BYD will equip all pure electric cars moving forward with this superior battery technology.
According to Chinese media CarNewsChina, the next-generation Blade Battery will be smaller and offer reduced energy usage per 100 kilometers traveled. Furthermore, its range will surpass 1,000 kilometers on one charge, alleviating some consumer anxiety surrounding pure electric driving.
4. Cell Pressure
The Blade Battery is a module-less battery designed with lithium iron phosphate (LFP) cell technology instead of the usual nickel manganese cobalt cells. When stacked together, individual cells reduce battery pack size by 50% when compared with traditional modules.
This allows the Blade Battery to have an outstanding structural design that can withstand enormous pressure, as evidenced by extreme tests such as the Nail Penetration Test or being run over by a 46-tonne truck without experiencing any adverse consequences.
It has also undergone rigorous design simulations in order to optimize its performance, with up to 8C charge rate capabilities allowing it to fully charge its capacity eight times an hour – increasing range and efficiency dramatically.
5. Charge/Discharge Rates
BYD has earned its place as a pioneer of pure electric vehicle innovation with their Blade Battery technology, used on all their pure EV models like Han EV which offers up an impressive 605km range with their Gen 2 Blade Battery installed.
The Blade Battery gets its name from its long individual battery cells that resemble sword blades. These batteries fit in half more cells per space than traditional lithium iron phosphate block batteries, as well as increasing energy density through their cell-to-pack design.
CarNewsChina reports that the next-generation Blade Battery will cost 15 percent less than its current version and support discharging at up to 8C, as well as having a shorter charge time of approximately 7.5 minutes due to increased energy density.
