Zero Motorcycles‘ Z-Force® battery is the most energy dense in the EV industry.
Individual bricks are what power the Zero FX model. Add 3 or 4 bricks together and you have what’s known as a “monolith” in Zero terms, which powers the S, SR and DS models. The three-brick monoliths are currently featured in ZF9.4 models, while the four-brick monoliths are used for ZF12.5 models. Zero’s optional Power Tank is simply a single auxiliary brick.  A typical Zero S or Zero DS can travel over 200,000 miles with the batteries retaining 80% of their original maximum capacity.
The current manufacturer of cells for Zero’s packs is Farasis who are supplying pouch cells. The chemistry used is Lithium Nickel Manganese Cobalt: LiNiMnCoO2 (“NMC”).
farasis li-ion battery
The 2016 32Ah Farasis pouch cell is capable of 4C continuous discharge with a peak of 10C.
2016-Gravimetric Energy 185 Wh/Kg, Energy Density 410 Wh/L Without tabbing
Farasis – started in 2002 in Silicon Valley, founded in 2009 in Ganzhou
Farasis pouch cell: high density conventional battery cell
Luke Workman  About 35% of the weight in the cell is current collection, sheets of aluminum and copper foil that are just there to get the energy in and out of the cell. That’s a lot of weight that’s not active material, a lot of weight to carry that’s not storing energy. Getting rid of packaging and those thick tabs that interconnect the cells in a regular battery can save a meaningful amount of weight on a large scale battery. Axial stack battery design could unlock the era of supersonic electric airliners. “I’ve come up with a battery design that weighs far less and handles heat insanely well – it just requires a gigantic, flat surface area. Like, say, the oversized wings of a supersonic plane.”
Farasis Energy is going to build a new production plant in Germany (on top of two already built in Ganzhou and Zhenjiang, China). The company intends to invest more than €600 million to install some 6GWh of production capacity and start production of cells, modules and even packs from 2022. In 2018 Farasis Energy raised more than $1 billion and announced a plan to increase Zhenjiang production to 20 GWh annually.
DIY 6kwh offgrid battery with LG chem cells
In the automotive battery industry, one of the most successful Li-ion chemistries is the
cathode combination of nickel manganese cobalt oxide (NMC).
(NMC) has similar or higher specific capacity than LCO and similar operating voltage
while having lower cost since the Co content is reduced. LiNi1/3Mn1/3Co1/3O2
(NMC-111) is the most common form of NMC.

To achieve driving ranges well beyond 300 miles in the future, the specific energy of today’s LIBs need be further increased to 300 Wh/kg and above. As previously discussed, layered lithium transition metal oxides (NMC) have become the most popular cathodes for automotive battery technologies.

By 2021, the Co amount in NMC-811 will decrease by 69% in contrast to that of NMC-111. Recently, many battery manufactures such as LG Chem and SK innovation have announced that they will start the production of new NMC-811 battery materials in the near future. In addition, BMW also expects to use NMC-811 battery cells in its new BMW i5 in 2021.

CATL achieves 304 Wh/kg in new battery cells

CATL’s NCM 523 battery cells (available since 2017):
Prismatic format: 235 Wh/kg and 570 Wh/L
Pouch format: 250 Wh/kg and 530 Wh/L
CATL’s NCM 811 battery cells with impressive energy density:
Prismatic format: 270 Wh/kg and 660 Wh/L
Pouch format: 300 Wh/kg and 700 Wh/L

2019: As we can see, there will be two generations of NCM 811 battery cells. While the first generation NCM 811 battery cells will have common anodes made with graphite, the second generation will get anodes made with graphite mixed with a bit of silicon to increase energy density. The battery cell sample with an energy density of 304 Wh/kg belongs to the second generation – and is probably still a year away from mass production. However, the first generation is ready and there are already at least two electric cars confirmed to get it in the coming months. They are the upcoming Chinese electric cars NIO ES6 and the GAC Aion S. Anyway, considering that the PEUGEOT e-208, DS 3 CROSSBACK E-Tense, Opel e-Corsa and the Volkswagen ID 3 (Neo) will have battery packs made with CATL cells, they might be the first European electric cars to get NCM 811 battery cells. In the case of the PSA electric cars we already know that the 50 kWh battery packs will be liquid cooled and be able to fast charge from 0 to 80 percent in 30 minutes – at 100 kW DC fast chargers. The other contestant is the Mercedes-Benz EQC, which is expected to get NCM 811 battery cells from SK Innovation later this year.

Reuters 2020 – China’s biggest maker of batteries for electric vehicles, has begun mass production of high-nickel batteries, its chairman told investors last Friday. The so-called NCM 811 battery contains 80 percent nickel, 10 percent cobalt and 10 percent manganese, it has a longer lifespan and allows electric vehicles to go further on a single charge. CATL, which is building a battery plant in Germany, is expected to further expand battery production capacity in the next two years.
