great talk and updates on states of batteries

What if there is a better way than batteries?

I like how self aware this presentation is as every new battery tech announced claims to be 'game changer' thee days.

Batteries have got the potential for at least twice the improvement over current lithium ion batteries... That is why l am betting on batteries and not hydrogen... Double the lifespan, double the energy density and half the charge time is easily attainable in the next ten years with a modest improvement in safety....👍 The future looks good if we can embrace clean energy while still being realistic about how the world really works...

I have a question or should I say a challenge and maybe someone in this comment section can take it on. Let’s assume money is not a problem. Is there’s a battery technology capable of producing 10 times the current batteries energy density while weighting half or ideally three times less than current battery technologies. I am whiling to pay 150000 dollars for one single pack of such a battery pack. Thank you in advance

An eclectic and hugely illuminating overview. Thank you.

Very good presentation, with a pinch of humour. That was interesting about the difficulty of recycling Li batteries, it seems a real waste of resources to throw them away, as we do currently.

My Tesla is 5 years old, has 200k miles and the battery is still going well. An average driver would need 15 years to drive that much. Looking at the data from hundred of Teslas with high milage, it will be at 80% capacity at aprox 500k miles. That's aprox 40 years worth of driving for an average driver. 80% capacity is considered the point at which the battery would be replaced. But at 80% capacity the car would still have plenty of range to do my daily driving. It would still have 220 miles of range. In other words, battery technology from 2012 is already more than good enough for automotive use.

One thing to keep in mind for battery swapping... you could do swaps between users which require regulations to protect users from other users with ill intent. However, there is also the “swap myself” options where you could leverage for my EV, then for my Powerwall or other use.

Nor Dic I’m not thinking of battery swap for transportation use. I.e. where you had concerns of taking too long at a recharge station. Rather, I was thinking of when you’ve used your car batt so much that it only retains 80% capacity... then, you can extend the batt life for household Powerwall use as it is still useful but perhaps you don’t want to lose 20% of your range in a car but in a household scenario you will have multiple batts so using it in that scenario should be fine.

Lots of funding put in for 'conventional' batteries, his company/royalties etc. However, I think Solid State is where the future is. If Sulphur is going to be involved, then maybe the cost ultimately might win over Solid State. Basically, everyone is trying to make a battery that's cheap to make, fast charge, many recharges, safe and the mineral resources on hand...

If you want a battery that lasts forever you need to forget about the concept of electo chemistry for good. My idea is to take 2 giant intex pools fill one with water put it as high as you can and the bottom one place in your basement , hook up 2 pipes , 1 pipe is passed through a 1000w-500w hydro generator dc or bigger pump that is connected to an inverter , the second pipe is passed through a very efficient brushless pump which is hooked to a solar panel array , water will continue to flow in a low phase driving the generator and when the sun shines /wind blows the pumps start to operate and pumping water to the higher pool (recharging the water up again) if you make the pools big enough , it could last for days and weeks without sunlight. Physical batteries are the future of energy storage .

I really see something cheap like Sulfur dominating non movable batteries. Cheap $/kW means we can use renewable wind and solar to power industry and residential, which can also be decentralised. With this much power available it will be more natural to drive electric cars.

Tesla offering engineering jobs to domestic Chinese market? No coincidence.

Energy density of batteries is currently much too low. I love electric motors, and would love to replace the messy 2-stroke racing engine on my shifter kart with an axial flux motor and battery pack. But the reality is that to build a kart to run for 33 minutes at full race speed (road racing) takes about 200 pounds of the most advanced batteries currently available VS about 6 pounds of gas/oil mix. Plus the motor controller, and BMS. It's not even close in weight, or cost. Maybe in 10-20 years we will get there. I'm all for it.

@Anorrea

you don't need as much energy density with electric motors, they are much more efficient thant thermal engines, which are able to put into mechanical work only 25% of input power, while electric motors transform 85% of input power into mechanical work, that's the whole idea. When the density of batteries doubles or triples the current ones no only will be able to sell thermal-only car engines, and arabs already know this.

@hallkbrdz

5 жыл бұрын

Did you read anything I wrote? The most efficient (power and weight wise) electric motors with the highest density batteries are much LESS efficient pound per pound than hydrocarbon based engines. It's not even close. I spent weeks researching and doing the math for my racing kart project (result above), and it is painful. It makes you sick, and you just shake your head. And not only are the batteries horribly low in energy density per pound, it is MUCH harder to cool an electric motor than an engine due to the difference in operating temperatures. Again, more math meeting physics. Then you add a needed tough crash safety cell for the current volatile Li-ion batteries, which of course adds even more weight. It just doesn't make sense, which is a shame, because I really wanted to do this. And I haven't even talked about the much higher cost. Go price a 18KWh 400v battery pack. Not cheap! For my case the energy density needs to increase 200/6 = 33.3 times to be roughly the same weight wise, and/or the motor/inverter efficiency needs to greatly increase (e.g. eliminate nearly all back EMF to start with) to be the same. Yeah but you say - hey, that's a 2-stroke - what about normal 4-stroke engines? OK - the weight difference is less. A simple 4-stroke non-turbo 300cc motorcycle engine making roughly the same power does weigh about double the 2-stroke 125cc motor. So let's just subtract that weight from the batteries. (200-45)/6 = 7.2 times. So even for that, I need to wait how many years? I WANT an electric motor kart. It would be awesome. But unless lightweight fuel cells finally become available, or some major battery or motor advancements happen - the math doesn't work. High speed = high drag = a large C discharge rate. This should also help you understand why electric motorcycles are so pathetic - for exactly the reason electric is not a good mix for racing karts. High speed, high drag, short battery life. Ask a Zero owner...

The different chemistries afford different advantages, the idea is to trade off cost, No of charge cycles, capacity and self discharge. From memory cobalt is added in trace amounts to get the charge cycles up at the cost of capacity. I hope they haven't made too may compromises. I have a 2017 Model S and have seen the indicated 80% charge range go from 346km to 342km over about 15,000km and it hasn't budged from that since. I got the 75kW battery because I had a few locations that I needed to be able to do round trips to. If my capacity drops below 90% I might be in trouble. I'm hoping a few superchargers or 3rd party fast chargers get set up before then, but at this rate I might not be driving any more before that happens. The other hope is that Tesla releases a solid state battery replacement before then that can be had for

And then to speak about the life of the battery by comparing them to your phone… After 3 years they don’t last as long? Our phones are improving everyday with new apps that require more energy from the battery. So they cannot last as long on a daily bases running new/more software that is continually running in the back ground. Plus those batteries are designed for quick charging and a shorter life in mind, as most people replace their phone every 3 years. I, and many others, have had our phones/batteries work just fine after 5+ years. As long as you are not running all of the latest and greatest apps all of the time in the back ground...

Seriously, nobody wants to replace their gasoline car with a model with worse characteristics. In no way. So, dear Cui, you can't get anyone excited about charging his battery in 15 minutes.

You can't, dear Cui, inspire anyone that his battery is heavier in weight than his conventional fuel tank filling. Approx. 35 kg. And you, dear Cui, can't convince anyone that his battery is larger in space than his previous petrol tank. The same goes for the range of a filling you can drive with it. Say 600 km. So you'd be strongly advised to take another bold approach. If you want to inspire someone, here's your recipe: all parameters for the future of your planned car's energy sources are twice as good as those of the energy storage device of the internal combustion engine. Everything else is just embarrassing. Translated with www.DeepL.com/Translator

The only thing which is embarrassing is this comment. I wouldn't expect anything less from somebody with a six part name which he produces in full on his KZread account, though.

With how much imagination, with how much visionary thought and how useful this commentary of Plans for the Creative Commons is, is left to the inclined user of the report to judge.

@@silberlinie Jesus, how much imagination and visionary thought do you expect me to pack into an off-hand rubbishing of your tunnel vision? You've listed several dimensions on which an electric car will probably never outperform a combustion engine, but said nothing of any of the benefits which could offset the downsides. You could have made an argument as to why no one would ever buy a car over a bicycle with the same logic. Some of those benefits: - Less noisy - Safer for kids (the ones riding in the car but also more generally - stand by the side of a busy road in gridlock sometime and try to breath, then imagine a baby or pregnant woman in the same situation) - Lower cost of maintenance and fuelling through the lifecycle of the car - Battery packs can be repurposed at the end of the car's lifecycle - Government subsidies will eventually shift strongly in favour of electric vehicles and away from ICE vehicles. - Inevitable future technological/societal/civil infrastructure developments which leverage the inherent nature of self-driving electric vehicles (mobile autonomous self-powered self-charging power banks with storage and passenger capacity) for purposes which extend beyond the current scope of our understanding, for which ICE vehicles would not be suited, accordingly adding a great deal of extra added value to the consumer and to society. Is that visionary enough for you?

How about a battery powered car replacing an oil powered car to start your waste of time ; all the rest of your comments/suggestions mean little to reality and logic
