当然，这并不是靠堆电池，而是基于材料创新和结构创新。

　　近日，瑞浦兰钧在其新品发布会上推出了“问顶电池”，基于方形磷酸铁锂材料，能量密度达到450Wh/L，可以让磷酸铁锂实现700km续航，产品将于明年交付。

　　紧接着，蜂巢能源在行业会议上透露，公司将于2023年推出能量密度195Wh/kg的磷酸铁锂短刀新产品，续航可达700km。

　　8月27日，宁德时代董事长曾毓群对外表示，通过材料体系创新，宁德时代推出了M3P电池。M3P电池基于铁锂电池又不是铁锂，保持了磷酸铁锂高安全长寿命的特点，电芯能量密度提升了20%，非常具有竞争力。通过M3P+麒麟电池结构，可以满足700km续航这一主流市场车型。

　　在与蜂巢能源的同一场会议上，中创新航透露，其已开发出OS高锰铁锂电池，结合PACK层面的创新，可以将磷酸盐系的电池续航提升到700km，“让600km~800km这一主流车型区间成本曲线的斜率变得更低一些。”

　　……

　　如果按照续航来划分，目前800km以上的属于小众高档车型市场;600km~800km属于主流电动车型市场，600km以下又是一个市场。当磷酸体系电池可以实现700km续航，凭借其成本和安全优势，无疑会加速电动汽车的普及。

　　对于电池企业来说，通过成本更低的磷酸体系电池，抢占600km~800km这一市场，不仅是技术实力强劲的体现，更是未来在这一主流市场分得更大“蛋糕”的关键所在。

　　梳理目前几家企业磷酸体系电池实现700km续航的创新来看，各家企业路径并不一致，但主要是通过材料和结构创新来实现的，如提升磷酸铁锂能量密度、开发磷酸锰铁锂，或者其它基于铁锂的M3P等材料，亦或者通过PACK创新，或者兼而有之。

　　但从各家企业规划落地、装车时间来看，明年将是各家企业大规模量产能提供700km续航的磷酸体系电池的一年。

Phosphoric acid-based batteries have a range of 700+ kilometers and the "track" is open

The battery life of phosphoric acid system batteries has been raised to 700 kilometers by battery companies.

Of course, this is not based on stacking batteries, but based on material innovation and structural innovation.

Recently, Ruipu Lanjun launched the "Ask Top Battery" at its new product launch conference. Based on the square lithium iron phosphate material, the energy density reaches 450Wh/L, which can enable the lithium iron phosphate to achieve 700km battery life. The product will be delivered next year.

Immediately afterwards, Honeycomb Energy revealed at an industry conference that the company will launch a new lithium iron phosphate short knife product with an energy density of 195Wh/kg in 2023, with a battery life of up to 700km.

On August 27, Ningde Times Chairman Zeng Yuqun said that through material system innovation, Ningde Times launched the M3P battery. The M3P battery is based on iron-lithium batteries, not lithium-iron batteries. It maintains the characteristics of high safety and long life of lithium iron phosphate, and the energy density of the cells is increased by 20%, which is very competitive. Through the M3P+Kirin battery structure, it can meet the mainstream market model of 700km battery life.

At the same meeting with Honeycomb Energy, China Innovation Aviation revealed that it has developed an OS high-manganese iron lithium battery, which, combined with innovation at the PACK level, can increase the battery life of phosphate-based batteries to 700km. The slope of the cost curve for a mainstream model segment has become a little lower.”

……

If it is divided according to the battery life, the current market of more than 800km belongs to the niche high-end vehicle market; 600km~800km belongs to the mainstream electric vehicle market, and below 600km is another market. When the phosphoric acid system battery can achieve a cruising range of 700km, with its cost and safety advantages, it will undoubtedly accelerate the popularization of electric vehicles.

For battery companies, to seize the market of 600km~800km through lower-cost phosphoric acid system batteries is not only a manifestation of strong technical strength, but also the key to a larger "cake" in this mainstream market in the future.

Looking at the current innovations of several companies' phosphoric acid system batteries to achieve 700km battery life, the paths of each company are not consistent, but they are mainly achieved through material and structural innovations, such as improving the energy density of lithium iron phosphate, developing lithium manganese iron phosphate, or Other materials such as M3P based on iron and lithium, or through PACK innovation, or both.

However, judging from the planning and loading time of various companies, next year will be the year when companies can mass-produce phosphoric acid-based batteries with a battery life of 700km.

Ruipu Lanjun: "Ask Top Battery" helps lithium iron phosphate achieve 700km battery life

Ruipu Lanjun achieves this by improving the volumetric energy density and battery pack utilization rate in the same battery system through the "top battery" technology.

According to Ruipu Lanjun, the top battery can make the volume energy density of the square lithium iron phosphate battery reach 450Wh/L, far exceeding the current industry level of 400Wh/L, making the lithium iron phosphate model enter the 700km battery life threshold.

Based on this technological innovation, the battery capacity can be increased by 15% under the same volume.

Phosphoric acid-based batteries have a range of 700+ kilometers and the "track" is open

It is understood that for the top battery, Ruipu Lanjun adopted "an integrated welding technology", which made the internal structure of the battery achieve an integrated connection, reducing the original top space from 15mm to 8mm, making the space utilization The rate is effectively increased by more than 7%. The top of the battery JR is basically close to the underside of the cover. This is also the reason why Ruipu Lanjun named the battery "Ask Top Battery". Through structural innovation, the space for improving the battery capacity can be obtained from the height of the battery cell.

In addition, Ruipu Lanjun will achieve mass production and large-scale supporting applications of lithium iron phosphate batteries with an energy density of 180Wh/kg in 2020. Continuous technological changes, combined with "asking to the top" technology, easily leap into the "club" of 700km battery life in the phosphoric acid system.

CATL: M3P+Kirin battery

It is understood that the M3P battery is a new material system battery developed by CATL based on iron lithium. Its energy density is about 20% higher than the existing iron lithium battery, reaching 210Wh/kg, and the cost is comparable to that of lithium iron phosphate battery. Some people speculated that the Ningde era M3P battery is lithium manganese iron phosphate, but it was denied. Because it is also doped with other metal elements.

It is reported that M3P batteries will be one of the important technical routes for future passenger car solutions in CATL. Wu Kai, chief scientist of CATL, said that in the mainstream new energy vehicle market with a range of 700 kilometers, CATL's solution is the M3P battery + Kirin battery structure, which is a combination of these two technologies.

Zeng Yuqun also said that it is the kingly way to let electric vehicles enter the homes of ordinary people, which are affordable, durable, and worry-free. Aiming at the mainstream new energy vehicle market, "We have launched M3P batteries through material system innovation. Based on iron lithium rather than iron lithium, it maintains the high safety and long life characteristics of lithium iron phosphate, and the energy density of the cells is increased by 20%, which is very competitive."

Honeycomb Energy: The energy density of lithium iron phosphate will reach 195Wh/kg

In terms of the layout of lithium iron phosphate, Honeycomb Energy has implemented a strategy of electric all-in-one short knife. At present, the mass-produced L600 lithium iron phosphate short knife battery can cover the market of A0~B level and above, and the power can meet the demand range of 50~100kwh, and can be used in storage at the same time. energy and light power markets. Yang Hongxin, chairman and CEO of Honeycomb Energy, said that in 2023, Honeycomb Energy will launch a new iron-lithium short knife product with an energy density of 195Wh/Kg and a battery life of up to 700km.

In addition, for the mainstream new energy market, Honeycomb Energy will also launch cobalt-free batteries to participate in the market competition. Among them, the layered cobalt-free material battery successfully developed by Honeycomb Energy leads the industry. At present, it has launched the world's first mass-produced cobalt-free battery, which will be mass-loaded on models such as the ORA Lightning Cat. Yang Hongxin said that Honeycomb Energy will launch the second-generation layered cobalt-free battery in 2023. The cost is expected to be close to that of lithium iron phosphate, and the battery life can reach 800Km.

Yang Hongxin also revealed that Honeycomb Energy is currently integrating all key technologies such as fast charging, high energy density, and high security through a system integration solution, combined with the innovative structure of Honeycomb Energy's short-knife cell, forming a lithium iron phosphate field. One of the industry's highest pack-efficiency solutions will release next-generation battery technology by the end of this year.

Zhongxinhang: OS high manganese iron lithium battery

According to Xie Qiu, senior vice president of China New Aviation, the One-stop high-manganese iron lithium battery developed by the company has completed the pilot test, and is currently carrying supporting models for reliability experiments, and plans to launch around 2024.

He revealed that the One-stop high-manganese iron lithium battery has an energy density of 180Wh/kg, can achieve a cruising range of 700km, and has a cycle life of up to 2,500 times.

Phosphoric acid-based batteries have a range of 700+ kilometers and the "track" is open

According to reports, the One-stop high manganese iron lithium battery has greatly reduced the amount of cobalt, nickel, lithium and other metals, of which the amount of cobalt and nickel is 0, and the amount of lithium per unit Wh is 15% lower than that of lithium iron phosphate batteries.

In terms of space utilization, the One-stop high manganese iron lithium battery has a higher ground clearance, which reduces the probability of battery bumping on the one hand, and on the other hand, improves battery repairability, reduces maintenance costs, and has both charging and battery replacement. function to enhance the user's energy-replenishing experience.

Xie Qiu said that based on the understanding of user safety, economy, energy replenishment, driving and other experiences, combined with relevant materials and structural innovations, the OS high manganese iron lithium battery developed has the following characteristics: The first is better safety. ; Second, the amount of precious metals is greatly reduced, thereby reducing costs; third, the height of the battery pack is reduced by 7%, and the ground clearance is higher, reducing the probability of bumping; Fourth, the energy density of phosphate battery packs has reached 180Wh /kg, the retention rate of energy density exceeded 80%; fifthly, it supports the cruising range of the whole vehicle to reach 700 kilometers. Sixth, it can be repaired and disassembled. Seventh, in terms of energy replenishment experience, it can be recharged and exchanged.

In fact, in May this year, BYD released a battery-body integration technology based on CTB (Cell to Body). BYD's CTB technology integrates the top cover of the battery pack with the traditional structure of the body floor to form a vehicle sandwich structure with "blade batteries" and trays on the top cover. The first CTB-based seal model, the long-range version has also reached 700km, and the battery uses a lithium iron phosphate blade battery.

It is foreseeable that in order to compete for the largest passenger car market of 600km~800km, more and more battery companies will work on the phosphate system in the future. At the same time, combined with structural innovation, the phosphate system will become the main battery in this market. route.
