Type 3, there is nothing better than lithium at present. ion battery.
Since its launch in 1991, rechargeable lithium batteries have been the standard for everyday technology equipment and electronic equipmentvehicle power.
Many more than 3 million electric vehicles in the world use lithiumion batteries.
But as the world moves in the direction of the electric future, it needs something better than lithium --
Ion batteries to keep up with the pace.
\"Lithium is almost on the wall now.
If you really want to increase energy density, you have to go to a completely different paradigm, \"said Mo, a professor of materials science and engineering at the University of Maryland.
More energy density means cheaper, lighter batteries that can last longer for a single charge.
Fortunately, the battery started.
Ups is trying to make better batteries for supercharged industrial products and consumer technology as well as electric vehicles, with lower cost, higher energy density and better performance batteries, this will charge a faster fee and a longer distance to travel.
Starting this year, a few
They think that the ups of the battery has greatly improved compared with the current lithium.
Ion technology will bring their batteries to the commercial market.
Gene Berdichevsky, CEO of Sila Nanotechnologies, said: \"It took us eight years, about 35,000 iterations of our material synthesis, to be commercially prepared . \".
Sila is just one of a few battery starts.
Ups has recently received significant funding to continue adjusting battery technology.
Alamida, California last year
Basedcompany received $70 million in Series D financing from several investors, including Siemens Global venture capital, to build its first commercial production line for silicon anode batteries.
This is the decade after cooperation.
Created by mechanical and energy engineer Berdichevsky, the seventh employee of Elon Musk Tesla, who led the development of the Tesla sports car battery system (
Car, also founded by Musk, was launched into orbit in 2018).
New Changes in lithium
The ion battery has been studied for about 10 years.
It\'s only now.
Ups is preparing for the commercial spotlight, which will take at least a few years, and maybe even a full decade.
\"The material needed for a car is equivalent to 10,000 smartphones or 100,000 smartwatches,\" Berdichevsky said . \".
\"We will start with consumer devices.
In the next five years, we will expand our cooperation with our automotive partners.
\"One of Sila\'s current car partners is BMW. Current Lithium
The material part and physical energy density of ion batteries are limited.
The new battery technology aims to improve the safety and energy efficiency of lithium
If the battery is overheated or damaged, there is no risk of fire in the ion battery. Each lithium-
The ion battery consists of four basic parts: anode and cathode-
Bookmark electrode for each lithium-ion cell —
Liquid electrolyte and separator.
When the electrolyte transfers the lithium ion through the separator to and from the anode and cathode, positive and negative currents are generated.
It is this process that generates the charge stored in the battery.
If the chemicals that make up the anode and cathode-
Graphite and some kind of metal oxide, respectively-
The heating is too strong, it will destroy the physical separator, which makes highly flammable electrolyte exposed.
Think back to the Samsung Galaxy Note 7 phone explosion, you can see the problem.
Maximum lithium content
The ion energy density today is about 260 watts.
Hourly per kilogram;
By contrast, most electric vehicles currently have power between 220 and 250 watts.
Hourly per kilogram
A new battery technology is reliable.
State, it is replaced not only with graphite anode composed of lithium metal, but also with a solid piece instead of liquid electrolyte and separator, usually ceramic, glass or flame-
Flame retardant polymer.
It\'s powerful to take this approach, Colorado-
Solid based manufacturers
In 2018, it received A $20 million National Battery from Series.
According to company executives, the batteries they are developing have increased their energy density by at least 50%.
The mysterious Stanford University-derived QuantumScape is also developing.
National batteries in cooperation with the public (@VOWLFDC16J-GB).
Last year, Volkswagen increased its stake with a $100 million investment.
PitchBook data show San Jose-based start-
Valued at $1. 75 billion.
According to a press release announcing the deal, the battery of QuantumScape will allow mass electronic products
Golf will travel 466 miles
Currently 186 miles-
In a single charge, it is equal to the range achieved by conventional gases.
Power car.
According to Volkswagen, QuantumScape\'s battery should be faster
Charging, much lighter than the current lithiumion batteries. Yet solid-
As one vice president of Nissan said last year, national batteries may not be available until the next decade.
Even QuantumScape\'s press release points to the 2025 commercial production target.
In a long time of reality
National Technology is a symptom of how the current battery factory is built.
They\'re used to treat lithium.
Ion production with liquid electrolyte and switching to solid material is more than just a process to replace the factory floor.
\"This is an emerging technology, in a very, very early stage of commercialisation,\" said Dean Frankel, head of business development at Solid Power . \".
\"In terms of scale, it only takes time --up standpoint.
When some start
Ups is committed to improving and expanding solids
National batteries like Sila nanotechnology want to take advantage of the current lithium
The ion manufacturing process brings the battery to market quickly.
Instead of creating a solid
National Battery, Sila simply replaces the graphite anode with a material made of silicon, which absorbs lithium ion faster than graphite.
More importantly, most lithium
Ion battery with graphite anode has Charging Function
The ratio of less than 1%, that is, the C rate. Start-
Ups, which uses silicon anode to develop new batteries, said that the C rate of their batteries is much better, which is to realize electricity-
The future of the car, because most people don\'t want to wait for more than an hour, because the car can be charged when it takes only a few minutes to refuel.
\"We can keep charging at 10 times the speed of conventional graphite batteries,\" said Robert . \".
Rango, CEO of Enevate.
Irving, California
The foundation for creating the next company
Lithium generation-
Silicon anode ion batteries have $0. 111 billion in funding, including investments by South Korean battery company LG Chem last year.
Rango said that Enevate\'s battery has been in use for 10 years and is about a year and a half away from the first commercial deployment of its technology, most likely on e-bikes and scooters
Nevertheless, the silicon anode battery has a potential disadvantage: the expansion of the silicon material, which means that the battery gets worse every time it is charged.
Both Berdichevsky and Rango said their respective companies had solved the problem.
\"Silicon is indeed expanding and that is one of the challenges facing the industry,\" said Lange . \".
\"We have been able to control expansion in our cells.
Our battery specifications are electric-
Vehicle requirements.
\"Those requests?
The battery is able to charge up to 80% after charging and discharging 1,000 times.
Long development schedules for these beginnings
Ups is a sign of how difficult it is to drive battery technology.
While improvements in the EV series are certainly one of the main impacts of better batteries, the current successor to lithium
Initially it is likely that ion batteries will be found in smaller items.
\"What you\'re talking about is the technological transformation of the generation that has to happen,\" Berdichevsky said . \".
\"Of the existing 150 batteries, there are already four commercial-related chemicals on the market.
Every time you go to these new chemicals, they get harder and harder.
