The world's fastest charging lithium iron phosphate battery has been released.
On tonight’s Jikrypton Energy Day, Jikrypton Automobile brought another of their core technologies – the Brick Battery.
First, let’s briefly experience the performance of this gold brick battery:
- Charging for 15 minutes increases battery life by more than 500 kilometers
- Volume utilization rate is 83.7%, the highest in the world
- Cost per kWh reduced by 14.8%
- Increase production efficiency by 40%
- Maximum charging rate 4C
- Maximum discharge rate 16C
Why can't lithium iron phosphate batteries achieve ultra-fast charging?
As soon as the press conference started, JiKr CEO An Conghui asked us this question.
As we all know, the current mainstream power batteries are divided into two categories: lithium iron phosphate batteries and ternary lithium batteries. The former has lower production costs, high safety, and long service life, and is very suitable for large-scale promotion and use. However, compared with ternary lithium batteries, lithium iron phosphate batteries have smaller energy density and relatively slower charging speed.
In short, in the same car, entry-level models generally use lithium iron phosphate batteries, while long-range models and high-performance models usually use ternary lithium batteries.
Ji Krypton was thinking: Can we make a lithium iron phosphate battery that is cheap, safe, and has good performance ? So, the gold brick battery appeared.
In JiKrypton’s view, this battery has achieved three “bests” in total.
01 The fastest charging speed
At the press conference, Jikrypton listed the mainstream fast-charging lithium iron phosphate models and compared the battery life improvement of 15 minutes of fast charging.
It can be seen that the Xpeng G9 and Xpeng G6, which are also on 800V platforms, can get 399 kilometers and 324.8 kilometers of battery life respectively with 15 minutes of fast charging; the Zhijie S7 long-range Max version has a battery life of 352.5 kilometers, and is equipped with a NRIC battery Ji Krypton 007, there is still a gap.
Jikrypton said that the BRICS battery has ultra-fast charging capabilities that can increase the battery life by 500 kilometers in 15 minutes. Even at a low temperature of -10°C, the charging speed of the BRICS battery is increased by 25%.
Of course, in addition to the battery itself, the number of ultra-fast charging stations also greatly affects the recharge experience. In this regard, Jikrypton can be said to be "far ahead" among independent new energy brands. Its ultra-fast charging piles have reached 2,261, which is more than twice that of the second-place Weilai, and all Jikrypton charging stations nationwide The peak power of the charging piles in the Krypton Supercharging Station exceeds 360kW.
Every extreme charging pile you see is a super fast pile.
02 Highest volume utilization rate
Under the same system, the power of Brick battery is 26% more than that of traditional lithium iron phosphate batteries, breaking the previous limitation that large-capacity lithium iron phosphate batteries can only be installed in large SUVs and MPVs.
The BRIC battery can do this not because JiKrypton has increased the energy density of the battery cells, but because it has improved the volume utilization of the battery cells .
Taking the industry-famous 4680 battery as an example, its volume utilization rate is only 63%. The volume utilization rate of ordinary lithium iron phosphate batteries is 66%. Even the ceiling of ternary lithium batteries has just exceeded 72%. The utilization rate of the BRIC battery has reached 83.7%, making it the power battery with the highest volume utilization rate in mass production in the world.
Jikrypton Vice President Xie Shibin made this analogy:
If the batteries of our friends are compared to the hotel-style apartments with the largest public area, then for the first time, BRIC batteries allow batteries to live in large flats with higher occupancy rates.
In order to eliminate the "common pool", Jikrypton has completely transformed the battery pack structure.
The BRIC battery adopts a compact sandwich structure consisting only of battery cells, upper covers, and bottom plates. JiKrypton has vertically raised the square ladder silo, increasing the volume utilization rate by 7.6%. Aviation-grade ultra-thin thermal barrier material is used between the cells, turning the original thick partition into a thin "screen", increasing the volume utilization rate by 6%. At the bottom of the battery, Jikrypton uses an integrated liquid cooling tray to replace the traditional water pipe structure, and the volume utilization rate is increased by 8.5%.
Not only that, compared with the traditional design, the total length of the wire used in the Brick battery is shortened by 157 meters, and the core components are reduced by 35%. Ultimately, the battery quality and energy density are increased by more than 10%, achieving a breakthrough in storage technology for lithium iron phosphate batteries.
03 The safest in the world
For Jikrypton, which has set a record of "delivering 180,000 units with zero spontaneous combustion", the "safety" card must not be lost. To build a safe electric vehicle, the performance of the battery is crucial.
In order to demonstrate the safety of the "Gold Brick Battery", JiKrypton used the same battery to conduct 6 consecutive "violent tests", namely:
- Soak in 10% salt water for 48 hours
- 1000°C flame roasting for 130 seconds
- -45°C extreme cold 8 hours test
- Towed 3 kilometers on bad road
- 22 ton road roller
- Falling from a height of 10 meters
The experimental results showed that after the first five tests, the gold brick battery was still able to drive the vehicle. After the "fall from high altitude", there was no fire or explosion, and the battery pack was intact.
In addition, Ji Krypton has also prepared three more rigorous experiments.
First, JiKrypton charges a gold brick battery to a fully charged state, and then uses an extrusion force of 1.5 times the national standard to allow the extrusion deformation to reach more than 30%. At this time, the battery core insulation film continues to stretch and twist. After leaving it for an hour, there was still no leakage or power loss.
Next, Ji Krypton used a 5 mm steel needle to pierce it from the point of greatest bending, causing the battery core to short-circuit. There was still no fire or explosion in the entire process, and the surface temperature of the battery core was only 33 degrees Celsius.
Last item: fire.
The external fire requirement under traditional national standard working conditions is 130 seconds without fire or explosion. In the real scenario, the escape time is a little more than two minutes. This time, Ji Krypton has extended the escape time to 240 seconds, a full 4 minutes.
Finally, Jikrypton CEO An Conghui said that the BRICS battery is not a "PPT battery". It has now completed mass production and will be launched on Jikrypton 007.
Ji Krypton 007, this 200,000-yuan “shit stirrer”, has another trump card.
It’s not just Jikrypton that’s eyeing the battery
Then am I not working for CATL now?
Zeng Qinghong, chairman of GAC Group, has always been reluctant to make public appearances, but his speech at the World Power Battery Conference made him trending on the same day. Not wanting to "work" for a battery factory is the aspiration of every car company leader.
Just this month, the Inpai Battery Intelligent Ecological Factory under GAC Aian was officially completed. The factory has a total investment of 10.9 billion yuan and will produce the latest product of the magazine battery 2.0 series, P58 microcrystalline super battery, for the Haopin brand. The announcement shows that its planned 36GWh power battery and energy storage battery production capacity can meet the installed capacity needs of 600,000 new energy vehicles.
In fact, not only GAC, but also OEMs such as NIO, Great Wall, Tesla, BMW, Volkswagen, and Hyundai have entered the battery track through self-research and self-construction or joint investment and joint construction. In this way, in addition to avoiding being "constrained by others" in terms of production capacity, the production cost of vehicles can also be significantly reduced.
In 2021, the new energy vehicle market will expand rapidly, and the demand for lithium battery materials from OEMs will enter a blowout period. As a result, the price of lithium carbonate will continue to rise. By the end of 2022, the average spot price of battery-grade lithium carbonate has soared 10 times compared with the beginning of the year, approaching 600,000 yuan/ton.
Although the price of battery raw materials has dropped significantly since this year, with the average quotation falling to 112,500 yuan/ton, there is still a gap of almost 2 times compared with the price in 2019. For OEMs, it is important to firmly control the battery industry chain. In your own hands, it is very necessary.
We will acquire mining companies in the future.
In May 2022, Tesla CEO Elon Musk repeatedly emphasized the importance of lithium mines to Tesla in an interview. In just one year, Tesla has quietly laid out its entire industry chain.
In May this year, Tesla officially broke ground on its new lithium refinery in Corpus Christi, Texas. The project has invested US$375 million and is expected to be completed and put into production in 2024. Tesla said that one year after the plant is put into operation, the production capacity will be enough to supply the power batteries needed for 1 million electric vehicles.
Quietly, Musk has built a huge battery empire for Tesla.
Nowadays, Geely also has a battery industry layout of over 10 billion in Quzhou. Today’s protagonist BRIC battery is from Quzhou Jidian, which is wholly owned by Geely. The company has formed a complete industrial chain in the four key components of lithium batteries: cathode materials, anode materials, electrolytes, and separators. As the delivery volume of its new energy models increases, battery costs will be further reduced, forming a more competitive market. terminal price.
Almost 100 years ago, Ford built a factory called "Rouge" in Michigan. It was once the largest automobile factory in the world.
The plant implemented the most advanced vertical integration model at the time, encompassing the entire manufacturing process from raw materials to vehicle assembly, and even included a mining site and a steel plant. Iron ore and coal are transported to the blast furnace via internal railways and processed directly into molds and auto parts, greatly improving manufacturing efficiency and costs.
For today's new energy car companies, such an integrated vertical supply chain has become a "basic". Not only batteries, but also the future competition areas will continue to expand.
Maybe in the end, every car company will have its own "Rouge factory."
