中国宁德时代在上海车展上宣布了一种新的电池类型。所谓的凝聚电池是一种半固态电池,有望提供 500 Wh/kg 的能量密度,同时比普通锂离子电池更安全。据宁德时公告称,新电池的能量密度为500 Wh/kg,远高于现有的锂离子电池。这几乎是特斯拉电池能量密度的两倍,特斯拉电池被认为是世界上最好的电池之一。宁德时使用高导电仿生凝聚态电解质来达到这一水平,这也解释了电池名称的由来。凝聚式电池具有超高能量密度正极材料和新型负极材料、隔膜和制造工艺。

So an EV with real equal range (if not better) to petrol vehicles (500w/ Kg) becomes a true turning point. It also has a 18,000 charge cycle life and charges at low temperatures -20C and a 4c charge rate, according to the Viking.Never mind Tesla all the manufacturers will want it, car and truck and plane.

那么一款续航里程与汽油车(500 瓦/千克)相当(甚至更好)的电动汽车将成为一个真正的转折点。根据维京人(博主)的说法,它还具有 18,000 次充电循环寿命,可在低温-20℃和 4c 充电速率下充电。不用担心特斯拉,所有汽车、卡车和飞机制造商都会需要它。

If this gets to cars in production.. it would really shut up all those that promote the fud of range problems of EVs ...

如果这能应用到量产汽车上,那么所有鼓吹电动汽车续航里程问题的人都会闭嘴......

There are considerable advantages to plane makers, airlines, and passengers.Jet fuel burns at roughly the same efficiency as petrol in cars, around 30%. That's why driving an EV brings the cost of driving down more than 70%.  

这对飞机制造商、航空公司和乘客都有很大好处。喷气机燃料的燃烧效率与汽车汽油大致相同,约为 30%。这就是为什么驾驶电动汽车能使驾驶成本降低 70% 以上。


This doesn't even count the savings in battery systems that don't require maintenance.That brings us to safety, which a battery powered plane achieves in two ways -- first by eliminating jet fuel, and second by reducing the risk of mechanical failure to almost zero.

这还不算无需维护的电池系统所节省的费用。说到安全性,电池驱动的飞机可以通过两种方式实现--首先是省去喷气燃料,其次是将机械故障的风险降低到几乎为零。

Unfortunately, unless it charges in less than 10 seconds, they'll still moan

不幸的是,除非它能在 10 秒内完成充电,否则他们还是会抱怨!

There's always a battery break through every week So far 100% of those haven't come to manufacturing volumes at any scale other than prototypes ..

每周都有一项电池突破,到目前为止,除了原型机之外,这些产品都没有达到任何规模的量产。

The pace of "breakthroughs" is crazy, but the production not so much.In the 15 years since Tesla started production of their Roadster, the battery is still pretty much the same with a couple of chemistry changes, no "crazy" changes.Toyota was supposed to have their SS battery in volume production two years AGO.  Every day we see a new "breakthrough", let's see these batteries 1) be proven and 2) be in volume production.

突破的速度令人疯狂,但生产却不尽人意。自特斯拉开始生产 Roadster 以来的 15 年中,电池的化学成分几乎没有变化,没有 “疯狂”的改变。丰田两年前就应该量产他们的 SS 电池。我们每天都能看到新的 “突破”,让我们看看这些电池:1)是否经过验证,2)是否能实现量产。

There are 3 different CATL batteries hitting the market in the year - sodium, improved LFP, and condensed aviation batteries. They do different things at different price points. There is no single silver bullet or holy grail, but these each are an amazing innovation on their own. Together they solve nearly all the battery applications I know of, from grid storage to airplanes.

今年有三种不同的宁德时代电池进入市场——钠电池、改进的LFP电池和浓缩航空电池。他们在不同的价位做不同的事情。没有什么灵丹妙药或圣杯,但这些电池各自都是了不起的创新。它们结合在一起,几乎解决了我所知道的所有电池应用问题,从电网存储到飞机。

Our next energy did that year's ago already with an in house prototype stock battery case model S, achieving 750+miles at hwy speeds in the cold Michigan weather and 850+in summer. You can find the videos on here of it.

早在一年前,我们的下一个能源公司就已经使用库存电池原型 S 车型,在密歇根州寒冷的天气下高速行驶 750 多英里,在夏季行驶 850 多英里。你可以在这里找到相关视频。


Same dude who sadly got sold out by the obummer admin when he was leading the a123 battery company providing the og fisker karma with cells and had lfp patents that then got sold out to China.

这就是那个不幸被奥巴马政府出卖的人,当时他领导的 A123 电池公司正在为菲斯科卡玛(混动超跑)提供电池,并拥有 Lfp 专利,后来被卖给了中国。

I have no doubt that CATL's condensed battery is real and already in production. The question is cost. The fact that it is currently deployed in commercial trucking application hints it is quite expensive.

我毫不怀疑宁德时代的浓缩电池是真实的,而且已经投入生产。问题在于成本。事实上,它目前已在商业卡车应用中部署,这暗示它相当昂贵。

As they are a very big producer already , they are in the best position to scale up to affordable levels very quickly. There will be an enormous demand if the price is available for cars.

由于他们已经是一个非常大的生产商,因此他们最有能力迅速将规模扩大到可承受的水平。如果汽车也能享受到这个价格,需求量将非常大。

The condensed matter battery does have very high energy density, but it is also about 10x the cost of their regular lithium batteries (such as the Shenxing 2 LFP battery). That is why it is focused on aviation.If they are putting it in trucks then I'm guessing they are just demonstrators, not an actual commercially-deployed product for trucks.

凝聚态电池确实具有非常高的能量密度,但其成本也是普通锂电池(如神行 2 LFP 电池)的 10 倍左右。这也是它专注于航空领域的原因。如果他们将其用于卡车,那么我猜他们只是在做示范,而不是真正用于卡车的商业产品。


4C charging means 1/4 of an hour from empty to full.1C = 1 hour from empty to full.The C-rate only relates to "range" when you also take into account the size of the battery pack installed in the vehicle.No matter the size of the pack, 4C means the entire pack can be charged from empty to full in 1/4th of an hour (15 minutes), for a range of XYZ (size of pack x 3 to 4 -ish).

4C 充电意味着从空载到充满需要 1/4 小时。 1C = 1 小时从空充到满。只有同时考虑到车辆中安装的电池组的大小,C-速率才与 “续航里程”有关。 无论电池组的大小如何,4C 表示整个电池组可在 1/4 小时(15 分钟)内从空到充满,续航里程为 XYZ(电池组大小 x 3 到 4 左右)。


In terms of cell life. LFP cells basically don't die, they just lose capacity slowly over time. Current LFP cells are generally rated around 3000 cycles at 80% depth of discharge per cycle to 80% of original capacity (after the 3000th cycle the battery has 80% of its original capacity). In an EV LFP technologies today can hit 6000. So 18000 is not actually that much of a stretch.

就电池寿命而言, LFP 电池基本上不会死亡,只是随着时间的推移容量会慢慢减少。目前的 LFP 电池一般额定循环次数为 3000 次左右,每次循环放电深度为 80%(第 3000 次循环后,电池容量为原始容量的 80%)。在电动汽车中,目前的 LFP 技术可以达到 6000 次。因此,18000 次实际上并不太夸张。


However, even though the cells might not die, the power electronics connected to those cells certainly will. This is the true limiting factor for a LFP battery pack... the BMS and power electronics inside the sealed battery and not so much the cells themselves.

不过,尽管电池可能不会坏,但与电池相连的电力电子设备肯定会坏。 这是 LFP 电池组的真正限制因素......是密封电池内部的BMS(电池管理系统)和电力电子设备,而不是电池本身。

It has always been just a matter of time before battery technology developed to the point where ICE cars were redundant. We're not there yet but I believe it will happen in the next ten years.

电池技术发展到让内燃机汽车成为多余只是时间问题。虽然我们还没有达到那个阶段,但我相信在未来十年内一定会实现。

Battery tech and the potential for specs that impress us. That is where I've slways focused. How and where they are used is secondary to me. Industries will find a way to utilize them, at a profit.

电池技术和潜在规格给我们留下深刻印象,这是我一直关注的重点。如何和在哪里使用它们对我来说是次要的,工业将找到利用它们的方法,并从中获利。

If this is true then it should reduce the weight of EV's then? Reducing the weight down to below that of an compatible ICE car is critical since it not only reduces the energy needed for movement but also reduces the wear and tear on any mechanical components, the four tires and the pavement.It may also enable the use of heavier more recycle able body components thus eliminating plastics altogether?

如果这是真的,那么电动汽车的重量就会减轻?将重量减至低于兼容的内燃机汽车的重量是至关重要的,因为这不仅能减少运动所需的能量,还能减少任何机械部件、四个轮胎和路面的磨损。此外,还可以使用更重、更可回收的车身部件,从而彻底消除塑料。

Current battery tech makes EVs the same weight as full size ICE SUVs, meaning the same weight is in a slightly smaller footprint.

目前的电池技术使电动汽车的重量与全尺寸内燃机 SUV 相同,这意味着同样的重量只需占用较小的空间。

Solid state has one huge advantage that will keep its development justified, it doesn’t explode or catch on fire. Pretty important if you want to put on an airplane where nowadays they limit even your laptop batteries.

固态电池有一个巨大的优势,它不会爆炸或着火,这将保持其发展的合理性。这很重要,如果你想把它放在飞机上,现在连笔记本电脑的电池都受到限制。

We are talking about different batteries here, developed for different applications. Instead of putting the same lithium batteries in everything, there is a special cheap battery (sodium) for budget EVs and bulk/grid storage.

我们在这里讨论的是为不同应用开发的不同电池。有一种特殊的廉价电池(钠电池)适用于经济型电动汽车和散装/电网存储,而不是在所有产品中都使用相同的锂电池。


There is a special automotive battery (LFP) that is more expensive, but is very durable, higher energy density, and very fast charging. There is a special aviation battery (condensed state), which is extremely high density, but will be so expensive it will only be used in airplanes and the highest performance luxury cars.

有一种特殊的汽车电池(LFP),价格较贵,但非常耐用,能量密度更高,充电速度非常快。还有一种特殊的航空电池(凝聚态),密度极高,但价格昂贵,只能用于飞机和最高性能的豪华汽车。

over the past 7 months we replaced our two ICE vehicles with two EVs. After having had the first one replaced and how easy and fun it was to live with, we replaced the 2nd one a month ago.

Range already seems to good on most new electric cars. It is charging infrastructure, repair and insurance costs that need to improve.

大多数新型电动汽车的续航里程似乎已经不错了,需要改善的是充电基础设施、维修和保险成本。

If these developments are commercially viable, current battery packs could be halved in weight but offer more density, this in itself will increase range. The same 80kwh battery pack would be substantially smaller and weigh less - but introducing more range. Not to mention cost reductions. It is every ICE car manufacturer's worst nightmare.

如果这些研发成果在商业上可行,那么目前的电池组重量可以减半,但密度更高,这本身就会增加续航里程。同样是 80 千瓦时的电池组,体积将大大缩小,重量也会减轻,但续航里程却更长。更不用说降低成本了。这是每个内燃机汽车制造商的噩梦。
