Summary
Honeycomb Energy said that based on cobalt-free batteries E platforms already have lithium iron replacement product performance and cost competitiveness in the car mileage.
"By 2025, we expect the global XEV power lithium battery installed 350GWh, with 65,000 tons of cobalt metal, cobalt-free if all batteries, can reduce the total cost of $ 2.6 billion."
This is a new cellular data Yang, president of energy given in the 2020 Beijing Auto Show, on cobalt-free cellular energy battery product planning conference on September 28, he said, want to cobalt-free cellular energy battery level to be achieved from the A00 class D application on all models.
Higher's lithium electronics learned that the honeycomb energy-free battery is divided into E platform and H platform, and the E platform is targeted for medium-standing models, cobalt battery products, and has alternative iron lithium competitiveness; H platform-free battery is for medium and high-end models and high-end The model has the performance level and cost competitiveness of replacing ternary high nickel on long miles.
E platform and platform-based H, cellular energy products planned four batteries, followed by the VDA 1.5x 90Ah capacity (size 39x148x102.5mm), 115Ah of VDA 2x (size 52x148x112mm), 115Ah of MEB 1.5x (size as) and a 226Ah L6 33.4x220x102.5mm (size 21.5x574x118mm).
4, paragraph two platforms batteries may correspond to different market positioning models, covering all models from more than 300-800 km, from a whole scene on the A00-D application-level model, and supports the whole category lifetime warranty.
Yang, president of the new cellular energy
As the field of power battery "New Horizons", cellular energy is the first publicly announced the development of cobalt-free materials and battery products business, its non-core electric cobalt project in early 2018, and the first breakthrough in the cobalt-free technologies, products .
The latest news is that cellular energy cobalt-free cathode material test was Ni75 ton in July this year off the assembly line, and implemented in September this year, equipped with cobalt-free materials like battery's first test vehicles on the road, to carry out road tests, leading the cobalt-free battery entered a substantive stage floor.
Cobalt-free batteries "ambition"
The honeycomb cell family based cobalt-free energy E and H internet platform, the corresponding cobalt-free batteries different in materials technology and market positioning corresponding to different models, covering all models from 300-800 km or more, application of the whole scene can be realized from the class A00-D model.
H-based platform to launch 115Ah and 226Ah two cobalt-free batteries, respectively, for high-end models and high-end models, now has a high nickel substitute three yuan in long-mileage car levels of performance and cost competitiveness.
Wherein, 115Ah without cobalt present energy density batteries up 245wh / kg, greater than 3000 cycles life, compared to the same level of high-nickel ternary battery, the energy density can be achieved by 2%, 50% longevity, cost reduction 8 %.
The batteries will be equipped with a pure electric A-Class Great Wall Motor plans, the life can reach 700km, while mounted on the pure electric SUV can achieve 600 + km endurance.
226Ah batteries for the high-end models, the third generation high-speed energy honeycomb-lamination process, this energy density can be achieved 235wh / kg, greater than 3000 cycles life, compared to the same level of high-nickel ternary battery, can achieve energy to enhance the density of 1.7%, life expectancy 50% cost reduction of 12.5%.
The product under PACK matrix design support, enabling the vehicle to break 800 kilometers the longest battery life level.
Release 90Ah and 115Ah two cobalt-free cell-based platform E, is mainly used in city cars, the cycle life can be more than 4000 times, compared with the energy density of lithium iron phosphate capacity increased by 20% and 17% reduction in the cost of .
Honeycomb Energy said that based on cobalt-free batteries E platforms already have lithium iron replacement product performance and cost competitiveness in the car mileage.
Honeycomb material cobalt-free energy path
Cobalt stabilizing structural role in the ternary material system material, once the "cobalt to" loop stability need to face 8% -10% high proportion of Li / Ni shuffling, low rate capability, and a high voltage system risks and poor , so the battery safety and cycle life settlement is very important.
As the first cellular energy publicly announced the development of cobalt-free materials and battery products business, its main bottleneck breakthrough cobalt-free technology uses three key technologies, namely cationic doping technology, networking and nano crystal coating technology.
Specifically, the introduction of the cobalt-free batteries E internet materials, mainly a high concentration doping and cationic nano network coating, micro-control of particle size lithium path optimization, capacity 2021 do 160mAh / g, 2023 in can upgrade to 170mAh / g.
H internet and electrically core material mainly nanonetwork coating technology, a single crystal technology, cation doped oxygen octahedron structures 2020 do capacity 180mAh / g, 2022 can be in up to 185mAh / g.
In addition, in the production process, the idea hive that is natural lamination process for the manufacture of batteries and long life, and in the manufacture of batteries in a long process, lamination process is more advantageous than the winding process.
E.g., based on cobalt-free batteries 226Ah platform H honeycomb-L6 is a third generation high-speed lamination process, may be implemented to enhance the energy density of 1.7%, 50% longevity, cost reduction of 12.5%.
