The following is extracted from Why building an
electric car is so expensive, for now.
I have left the article’s points answers to the questions raised intact,
and added what Red Sycamore and Quantum Age Holdings Corporation can do with
our product.
1. Why are EV batteries so
expensive?
They said:
Largely because of what goes in
them. An EV uses the same rechargeable
lithium-ion batteries that are in your laptop or mobile phone, they are just
much bigger to enable them to deliver far more energy. The priciest component in each cell is the
cathode, one of the two electrodes that store and release a charge. That is because the materials needed in
cathodes to pack in more energy are often expensive: metals like cobalt,
nickel, lithium and manganese. They need
to be mined, processed and converted into high-purity chemical compounds.
We say:
Our batteries are produced using
existing high-volume manufacturing equipment that has been tested and proven
for 30 years. Our batteries have no
anode active materials such as graphite, and we are not involved in anode
manufacturing. As such, formation and aging
is significantly reduced. There are no
expensive and difficult-to-produce ceramic separators or solid electrolytes. The additional system-level benefits of our
batteries, due to our material science and technologies involved, reduce weight
and volume. This brings down costs
significantly, by around 40-50%. We do
not need to use cobalt, copper foil, aluminum foils and such like.
2. How much are we talking?
They said:
At current rates and pack sizes, the
average battery cost for a typical electric vehicle works out to about US$7,350
(S$10,000). That has come down a lot –
87% over the past decade, according to BloombergNEF. But the average pack price of US$156 per
kilowatt hour (kWh) - from about US$1,183 in 2010 - is still above the US$100
threshold at which the cost of an EV should match a car with an
internal-combustion engine. That would
help trigger mass adoption.
We say:
Our production takes out expensive
processing in traditional electrolytes. Other batteries have solid electrolytes, which
are expensive to process and not compatible with the current lithium ion
process and equipment. This is in
contrast with our drop-in solution, inexpensive processing. Our product is non-flammable and biodegradable.
All these manufacturing elements reduces
our costs by 32% to 40% compared to any existing producer in the world. We own our patents so no one is able to
replicate that without us being involved.
3. How will the batteries get
cheaper?
They said:
Costs are not expected to keep
falling as quickly, but lithium-ion packs are on track to drop to US$93 per kWh
by 2024, according to BNEF forecasts. To
get there, one focus for manufacturers is replacing high-cost cobalt with
nickel. That has a double benefit: Nickel is cheaper and it also holds more
energy, allowing manufacturers to reduce the volume needed. On the other hand, cobalt’s advantage is that
it does not overheat or catch fire easily, meaning manufacturers need to make
safety adjustments when they use a substitute.
Panasonic in Japan plans to commercialise a cobalt-free version of a
high-energy battery in two to three years; other suppliers already produce
lower-energy ones. There is also
attention on the battery packs, often resembling oversized suitcases, that
house rows of individual cells. Simplifying
the design, and using a standard product for a range of vehicles - rather than
a pack tailored to each model - will deliver additional savings.
We say:
Our G3 Fireshield™ is a
non-flammable electrolyte that provides the safety of a solid electrolyte with
the performance of a traditional electrolyte. Our drop-in process reduces costs
tremendously. We do not need to use all
the expensive elements used in traditional electrolytes which have high safety
concerns and flammability. Our batteries
cost less than $100/kWh, with some customer feedback putting it as a reported less
than $85/kWh. Our energy density is more
than 400 Wh/kg; 1000 Wh/L, and uses our G3 Fireshield™.
4. Who are the biggest
manufacturers?
They said:
Asia dominates manufacturing of
lithium-ion cells, accounting for more than 80% of existing capacity. The majority of that might is in China. Europe is building new factories and will surpass
North America in cell manufacturing starting in 2021, according to Wood
Mackenzie. Overall, the Chinese company
Contemporary Amperex Technology (CATL) shipped the highest volumes in 2019,
including batteries bound for power grids and storage systems. It is a tighter field in the race to supply
automakers, where Panasonic led last year. South Korea’s LG Chem has surged ahead in
2020, capturing about a quarter of the market in the first eight months,
according to SNE Research. Tesla and
Panasonic’s joint venture is the biggest battery producer in the US. Emerging producers include Northvolt in
Sweden, founded by former Tesla executives.
We say:
G3
is the world’s largest graphene producer. G3 adheres to strict environmental,
health and safety procedures. Graphene is in a new class of advanced nanomaterials. As the largest global producer of graphene, G3 honours the challenge to set standards not just for technology but for
quality as well. G3 is ISO-9001:2015 certified for the
design, development, manufacture and testing of graphene and graphene-enabled
products and thermal management materials. We deliver world changing, life enhancing and cutting
edge technologies through graphene-enabled
solutions and products through Quantum Age Holdings Corporation globally.
5. Are all EV batteries the same?
They said:
Lithium-ion technology has dominated
the rechargeable-battery sector since it was commercialised by Sony in 1991. Improvements to lifespan, power, weight and
costs have helped the components leap from camcorders to SUVs, buses, and
ferries. While lithium-ion cells, like
all batteries, have the same basic components: two electrodes - a cathode and
an anode - and an electrolyte that helps shuttle the charge between them, there
are differences in the materials used, and that is key to the amount of energy
they hold. Grid storage systems, or
vehicles travelling short distances, can use cheaper and less powerful cathode
chemistry that combines lithium, iron and phosphate. For higher-performance vehicles, automakers
favour more energy-dense materials, such as lithium-nickel-manganese-cobalt
oxide or lithium-nickel-cobalt-aluminium oxide.
Further refinements are seeking to improve range - how far a vehicle can
travel before recharging - as well as charging speed, while also balancing
factors like fire-resistance. Recent
battery blazes and vehicle recalls have highlighted safety issues.
We say:
No. Our batteries exceed next-generation EV requirements
by providing an energy density of 400-500Wh/kg. Refer to our chart here below on all current
major players in the market.
6. How else can costs come down?
They said:
There is the manufacturing process
itself and the machinery required. Tesla
has commissioned the largest casting machine ever made that will produce the
entire rear section of a car as a single piece of die-cast aluminium. Integrating the battery with a vehicle
chassis could also trim the volume of material used. Electric motors - which account for as much
as a 10th of a car’s cost - should be about 5% cheaper in the next
couple of years with improvements to both materials and the electronics that
transmit power between the battery, motor and a vehicle's wheels, BNEF says.
We say:
Tesla cannot produce the performance
of the battery with 400-500Wh/kg at this moment in time. They have the money but do not own the
technology and research development team that QAHC has, nor do they have our
partnership with MIT. We have a
deliverable product now, and are already manufacturing for our JV partners in
Germany and USA. Our
batteries are already cheaper to manufacture, and with growing economies of
scale, that will drop further. Our base
materials is carbon, from plants.
7. So China is in pole position?
They said:
Yes, in almost every aspect, with
some key exceptions. China is
responsible for about 80% of the chemical refining that converts lithium,
cobalt and other raw materials into battery ingredients, though the metals
themselves are largely mined in Australia, the Democratic Republic of Congo and
Chile. China also dominates processes to
make battery parts including capacity for cathodes, anodes, electrolyte
solutions and separators, BNEF data shows.
But China faces a rare challenge when it comes to advanced semiconductor
design and software, components that are increasingly important as vehicles become
more connected and autonomous. Less than
5% of automotive chips are made in China, according to China EV 100, a
think-tank. For example, major players
in so-called insulated-gate bipolar transistors include Infineon Technologies
and Semikron in Germany and the Japanese companies Mitsubishi Motors, Fuji
Electric and Toshiba. These
high-efficiency switches reduce power loss and improve reliability in electric
cars.
We say:
China does not have the technology
in battery management and the intellectual property and patents we own to
produce batteries. Nor are they able to reverse
engineer our technology which is black boxed and proprietary. It is validated at MIT and by different
organisations that have independently tested and provided reference and test
reports on our performance of our batteries. In contrast, Quantum Motors has an 80-90%
reduction in electronics.
8. Is cost the only hurdle?
They said:
There is still an issue with driving
range. While the most-expensive EVs can
travel 640km or more before a top-up, consumers considering more mainstream
models remain anxious about how often they will need to recharge. Automakers and governments have become
directly involved in the roll-out of public recharging infrastructure,
conscious of a need to allay fears over not finding an electric pump on the go. Countries from China to Germany to Canada are
building charging stations as part of stimulus measures adopted to combat the
coronavirus-induced economic slump. Millions
of units are being fitted on highways, in suburbs and at shopping mall parking
lots, but distribution is uneven - more than a quarter of all public connectors
in the US are in one state, California - and not all chargers are compatible
with every EV model. Most recharging is
expected to take place at home, and that means another cost for consumers, with
an average price of about US$1,000 per system.
We say:
Cost, performance, energy density and life span
of the batteries is not found in any current lithium ion battery producer
anywhere in the world that matches the performance QAHC’s technology. Our batteries cost 40% or more less overall. This value will increase logarithmically over
the next 18 to 24 months. We have a head
start of 18-24 months and can commence manufacturing within 30-60 days for new
clients.
9. What is around the corner?
They said:
A host of innovations are seen
moving from laboratories to production lines by the end of the decade. California-based Sila Nanotechnologies is
adding silicon into battery anodes in place of graphite to allow a single
charge to last at least 20% longer. Toyota
Motor and US start-ups, including QuantumScape, are racing to commercialise
solid-state lithium-ion batteries, which overhaul a cell’s architecture to
replace the flammable liquids that enable charging and discharging with
ceramic, glass or polymers. That is an
advance that advocates claim can boost energy storage, lower costs, improve
safety and cut recharging times. CATL is
ready to produce a super long-life battery that lasts 16 years and two million
km - a typical battery warranty today covers about 240,000km or eight years. That means a single pack could be deployed in
multiple vehicles or for several different tasks. As early electric cars retire, there is also
a fast-developing sector aimed at reusing batteries for less-strenuous tasks,
or recycling the metals within them. Electric
vehicles should account for 10% of regular car sales by 2025 and 58% in 2040,
BNEF forecasts.
We say:
Our batteries can last 1 million
miles. After that, we return to factory
and refresh them for another million miles. We are already producing the batteries in
limited quantities for our test and pre-production schedule. Our manufacturing can commence in 20-30 days
from get go. We will at best be able to
deliver by year end to customers. The
closest competitor is QuantumScape Inc. who can only deliver a prototype in Q2
of 2023. We can deliver by end of Q3 of
this year, by commencing production in July 2021 onwards.
