Apparently they are located in Phoenix. I presume they will do hot
weather testing :)
If this isn't vaporware, that will be a great improvement, e.g. a 100kWh
battery at 200kg. No mention of size density but I would assume it's
also reduced by about the same proportion. The weak spot will by the
number of cycles. No mention on depth of discharge or charge, but 2000
doesn't sound so great (6 years for heavy usage), especially compared to
Tesla who appears to be much higher than that.

Nikola’s new battery tech challenges lithium-ion’s supremacy in the battle
to power our vehicles, homes, and businesses
]
The Nikola Motor Company dropped a bomb on the electric vehicle industry
today with news of a pending acquisition of a team that has developed next
generation battery technology. The news comes with claims of a cathode with
4 times the energy density of today’s lithium-ion cells, lasts for 2,000
cycles, and at a cell cost of 50% less than today’s lithium-ion cells.
If Nikola can bring a battery with these specs to market and produce them at
scale, the implications to not just the world of electric vehicles, but to
the entire automotive industry and to the world of stationary energy storage
would be profound. But that’s a big if. Thanks to unprecedented investment
in battery research and design, prototype batteries and breakthroughs in the
lab happen nearly every week, but they don’t always translate into real
world improvements.
In this case, Nikola’s outspoken CEO Trevor Milton feels the company has
found the real deal with news that it has filed a letter of intent to
acquire the team that developed the new tech. The acquisition is not
finalized at this point, but Milton hopes to announce more details
surrounding the breakthrough at Nikola World next fall.
For now, here’s what we know:
Cathode with 4x the energy density of lithium-ion
Prototype achieved 2,000 cycles in testing with “acceptable” end-of-life
performance
Cost 50% less to produce next generation cells per kWh compared to
lithium-ion
Weighs 40% less than same capacity of lithium-ion cells
Prototype cell achieved 500 watt-hours capacity
“This is the biggest advancement we have seen in the battery world,” said
Trevor Milton, CEO, Nikola Motor Company. “We are not talking about small
improvements; we are talking about doubling your cell phone battery
capacity. We are talking about doubling the range of BEVs and
hydrogen-electric vehicles around the world.”
Batteries are the glue that holds the worlds of electric vehicles,
renewables, and distributed generation together. While lithium-ion batteries
have continued to improve in energy density and cost at a steady pace in
recent years, the broader industry has had its sights set on the next
generation battery cell technology. Nikola’s new team has developed a
prototype cell that delivers on the promises of future battery technologies,
with an energy density of 1,100 watt-hours per kilogram for the material and
500 watt-hours per kilogram when rolled into a cell.
Bringing 500 watt-hour cells to market would be a nice bump in energy
density and at a lower cost than batteries going into production electric
vehicles today. The path to market for the new battery tech is not going to
be an easy one as Nikola will need to build or license manufacturing
capacity for the new cells. It is exactly this bump in the road that
mainstream automakers are wrestling with now as the Chinese battery
manufacturing engine continues to spool up to fill the need. Indeed, to meet
its needs at its Shanghai Gigafactory, even Tesla contracted out the supply
of battery cells.
Nikola plans to share the intellectual property (IP) for the new batteries
with OEMs that contribute to a new battery consortium. The move has the
potential to catapult not only Nikola, but the world of automobiles into
electric vehicles at a rapid clip. It shows that Nikola sees the need for
battery cell standards that stretch beyond its walls and into the broader
industry to achieve the manufacturing scale required to bring the cost down
for everyone.

Not that Nikola is planning to just give the tech out for free. It has big
aspirations for itself, with customer discussions about orders that would
propel it into the upper echelon of truck manufacturers. “Nikola is in
discussions with customers for truck orders that could fill production slots
for more than ten years and propel Nikola to become the top truck
manufacturer in the world in terms of revenue,” Milton said. “Now the
question is why not share it with the world?”
Of course, Nikola must first establish its own manufacturing presence that
can keep pace with the lengthy list of heavy truck manufacturers
aggressively moving into zero emission trucking including Mercedes, Volvo,
BYD, Tesla, to name a few.
The details of the new battery deal have yet to be shared, but for now, it
is clear Milton and his team at Nikola see promise in batteries ... The
world will have to wait until next fall to see them in action as Nikola
plans to showcase the batteries charging and discharging at Nikola World
2020.
