LFP Share Increasing (Slowly Outside China) Driven by
Cost Pressures
Europe and North America dominated by NMC and NCA with shift toward mid-nickel, then high-nickel variants.
LFP the most widely used chemistry in China. Though there was a small unexpected drop in 2022 from 2021, the
share of LFP use is still expected to grow due to cost and safety pressures and improvements to pack-level energy
density.

Manganese-rich cathodes.
Recent increase in activity driven by costperformance trade-off requirements.
LMR-NMC cathodes could lead to cost
reductions of ~10% compared to NMC 811 at
the cell level.
LMFP to enter market alongside other cathode
chemistries including manganese-rich and highvoltage LNMO.

Funding for Silicon Anodes Continues
Cumulatively, funding into silicon anode start-ups
and companies has exceeded US$4 billion since
2010 Over US$1 billion in 2021 and 2022 each.
Investment in 2023 has slowed significantly –high
level of previous investment, slow global economic
growth and high borrowing costs likely to be
contributing factors.
Funding continuing to be made available to startups and early-stage companies developing silicon
anodes.
Players building and expanding commercial-scale

Thoughts on SSBs in the Market
Most of the commercialized or to be commercialized batteries
equipped in vehicles in near future are not true all solid-state
batteries (ASSBs).
True ASSBs can take time and they are still pursued by most
players.
Hybrid SSBs can be a good transition, no matter from value
proposition point of view, or marketing point of view
EV is still the major market driver, although other markets are
easier to realize (there are already niche applications with
SSBs)

Best cells used
Bypasses complex disassembly procedures
Improves how competitive these
systems are with new Li-ion batteries
for SES
Cheapest form of repurposing
Supply side flexibility, can string packs of different designs
together
Most time consuming and expensive
process (reassembly also needed).
Performance of system affected by worst performing cell
Could damage well-performing cells in
the process – losing value
Relying on OEM providing packs with pre-specified
performance requirements
May be leaning more-so on battery analytics to improve
system longevity

Energy and Power Decoupling
− Electrolyte storage tanks only need increasing to increase storage duration, i.e., power and energy can be scaled independently.
− Results in CAPEX only increasing with tank size and electrolyte volume.
− As system size increases for Li-ion, CAPEX increases proportionally – makes Li-ion less feasible from an economic perspective for longer
duration technologies.

Concluding Remarks
Why?
Market Growth
Second-life
Maximize battery value and
delays recycling.
Second-life market in nascent stage, many
technical considerations and few startups.
Expected to grow at slower rate to
recycling market.
Recycling
To extract valuable materials;
shielding against supply
bottlenecks, price fluctuations
and to domesticate supply.
Many established players continuing to
expand recycling capacities globally.
Policies also a driver in key regions.
RFBs and other LDES
technologies
Critical Li-ion material supply
constraints and increasing
growth of VRE sources will
increase demand for other ES /
LDES technologies.
LDES technologies being developed and
commercialized by players globally. Greater
demand for LDES likely sooner in key regions,
e.g., California, Australia, Europe.

Steam-Methane
Reforming (SMR)
• Incumbent technology
• Can be retrofitted with
post-combustion CO2
capture
Partial Oxidation
(POX)
Autothermal Reforming
(ATR)
Turquoise Hydrogen
Methane Pyrolysis
(e.g. plasma pyrolysis)
• Commonly used for onsite hydrogen production,
e.g. petroleum refining
• Useful for conversion of
waste oil feedstocks
• Relatively new technology
• Combines principles of
SMR & POX
• Promising & popular for
greenfield projects
• Promising technology that
generates no CO2.
• Can use electricity
• Hydrogen classified as
turquoise
Coal (or biomass)
Gasification (CG)
• Commonly used in power
generation and chemical
production
• Popular in China
• Very carbon intensive
Natural gas reforming will dominate blue H2 production over the next decade
