BYD blade battery is an innovative battery technology introduced by BYD company, which has a number of significant advantages and features. The following is a detailed analysis of the blade battery:
advantage of BYD blade battery ：
• High safety : The BYD blade battery is made of lithium iron phosphate cathode material, which has high temperature resistance and can effectively prevent thermal runaway under extreme conditions. Its unique “honeycomb” structural design helps to disperse heat quickly, further reducing the risk of thermal runaway 1. In acupuncture tests, blade batteries performed particularly well, far better than conventional batteries 1.
•High energy density and long battery life : Through innovative structural design and the application of new chemical materials, BYD blade batteries achieve a high energy density, thereby improving the driving range of new energy vehicles. Compared with traditional lithium iron phosphate batteries, blade batteries have a significant increase in energy density, and the driving range can be increased by more than 50% 23.
• Long life and low attenuation : BYD blade battery cycle life is long, after a lot of tests and verification, its life can reach more than twice the traditional ternary lithium battery. This means that blade batteries have a low decay rate during long-term use and can maintain high performance stability 1.
•Cost advantage and environmental protection : BYD blade battery further reduces the cost through modular structure design and efficient production process, and promotes the popularization and promotion of new energy vehicles. At the same time, the blade battery material can be recycled with high utilization rate, which helps to reduce environmental pollution and resource waste .
•High space utilization and lightweight design : The flat design of the blade battery enables the battery pack to make more efficient use of the vehicle chassis space. This design not only improves space utilization, but also reduces the overall weight of the battery, helping to reduce energy consumption and improve vehicle performance.
Disadvantage of BYD blade battery :
•Low temperature life affected : Although blade batteries perform well at high temperatures, the range of lithium iron phosphate batteries will be affected at low temperatures. The careful design of the battery cell and battery pack, combined with an efficient thermal management system, can alleviate this problem to a certain extent, but there is still a low temperature life attenuation .
•difficult to repair : because the structure supporting the battery cell is omitted, the battery cell is easy to affect other cells after damage, increasing the difficulty of repair 2.
Application scenario
BYD Blade batteries are mainly used in BYD’s electric vehicles and commercial vehicles, such as Han EV, E-VALI electric VAN and other models. Its high safety, long life and low attenuation characteristics make it excellent in long-distance transportation and everyday use 12.
To sum up, BYD blade battery with its high safety, long life, high energy density and low cost advantages, in the new energy vehicle market has a significant competitiveness, but also need to pay attention to its endurance in low temperature environment.
The Tesla’s 4680 batttery is a new battery released by Tesla on Battery Day on September 23, 2020, with a diameter of 46 mm and a height of 80 mm, hence the name 4680 battery. The design and performance of this battery have been significantly improved in many aspects, and the following will be analyzed in detail from the aspects of technical advantages, cost effectiveness, and market impact.
Advantage of Tesla’s 4680 batttery:
Energy density and battery life : The energy density of the Tesla’s 4680 battery reaches 300Wh/kg, compared with the previous 2170 battery, the energy density is increased by 5 times, and the battery life is increased by 16%. This means that if the range of a car is originally 500 km, with Tesla’s 4680 batteries, the range can reach 580 km 12.
fast charging capability : Tesla’s 4680 The power of the battery is increased by 6 times, the fast charging capability is significantly enhanced, the charging time is greatly shortened, and the energy loss in the charge and discharge process is reduced, which improves the overall performance and service life of the battery 34.
Production efficiency : The Tesla’s 4680 battery adopts the design of no pole ear, which reduces the internal resistance and heat, and improves the charging speed and energy efficiency. In addition, the larger size and capacity means fewer batteries and a more simplified battery management system, reducing manufacturing costs and improving production efficiency 12.
cost-effectiveness:
Production cost : The Tesla’s 4680 battery’s design reduces the need for expensive and toxic cobalt, significantly reducing the battery’s production costs. The scarcity and high price of cobalt has always been an important part of the cost of batteries, and removing the dependence on cobalt makes batteries more competitive on price 34.
Environmental impact : Reducing the use of cobalt not only reduces production costs, but also reduces environmental pressure. The mining and processing of cobalt has a significant impact on the environment, and the use of Tesla’s 4680 batteries helps to promote sustainable development 34.
Market impact:
competition : Tesla plans to mass-produce the Tesla’s 4680 battery, which is expected to take another three years to go into full production. Domestic enterprises such as Ningde Times and Yiwei Lithium Energy are also laying out Tesla’s 4680 battery production lines, and the market competition will be more intense .
industry impact : Tesla’s 4680 battery poses a challenge to traditional battery manufacturers such as Ningde Times and BYD, and promotes the popularity and development of new energy vehicles .
Future prospect
The future prospects of Tesla’s 4680 batteries are very much worth looking forward to. Tesla and Panasonic plan mass production, domestic enterprises are also following up, with the continuous maturity of technology and the gradual acceptance of the market, Tesla’s 4680 battery is expected to become the mainstream battery technology, to further promote the development of electric vehicles 12.
To sum up, the Tesla 4680 battery has demonstrated its great potential in the field of electric vehicles with its outstanding technical advantages, significant cost effectiveness and far-reaching impact on the market.
Conclusion：
Byd’s blade battery has received widespread attention for its excellent safety, and many BYD 4S stores will conduct acupuncture tests to demonstrate its excellent performance.Tesla’s 4680 battery, as a new battery technology, uses a “non-pole ear” design, which greatly reduces battery heat and significantly improves charging speed.However, although the Tesla’s 4680 battery performs well in terms of charging and heat control, its increase in vehicle life is not as expected. Due to the large volume of the single unit, the number of batteries is reduced, and the improvement of battery life is not obvious.In contrast, BYD’s blade batteries show advantages in terms of safety, number of cycles and structural strength. Moreover, the cost of the blade battery is also lower than that of the Tesla’s 4680 battery.
