Adden Energy Announces World’s Fastest Lithium Metal Battery Has Achieved Breakthrough Low Temperature Performance

Adden Energy, a leading developer of solid-state batteries,
announces that its record-breaking lithium metal batteries can now
maintain extreme-fast-charging (EFC) of less than 10 minutes at
room temperature. No other lithium metal batteries can reliably
charge this fast even at elevated temperatures, nevertheless at the
room temperature required for electric vehicles (EVs). Such EFC
solves one of the biggest bottlenecks facing widespread adoption of
EVs.
“The slow charge rates of Li-ion batteries have made EVs
inaccessible to too many,” said Will Fitzhugh, CEO of Adden Energy.
“Over a third of American’s lack dedicated at-home parking, so the
current paradigm of at-home charging just doesn’t work. Our
technology makes EV charging as fast as gas, so you can recharge
using public infrastructure on your lunch break or the way home
from work.”
Adden Energy’s all-solid-state pouch cell batteries (ASSB) use
lithium metal anodes and high nickel NMC cathodes, enabling energy
densities up to 500+ Wh/kg. Patented innovations, including the
multi-electrolyte separator and porous 3D lithium metal anode,
enable the simultaneous EFC along with industry leading energy
densities.
In 2022, Adden Energy raised a $5.15M seed round to transition
the underlying technology from academic style pressed-powder coin
cells into commercially-viable pouch cells for the EV industry.
Based at its laboratory in Waltham, MA, Adden Energy has
successfully made this transition and passed several testing
criteria for adoption by EV manufacturers. This includes both
reducing the required temperature for EFC to room temperature and
maintaining conventional charging rates down to below
-20°C.
“The IP portfolio we’ve developed to enable
extreme-fast-charging at room temperature in our lithium metal
cells covers every aspect of the battery. Our porous anode
technologies allow high cathode loadings in excess of 4 mAh/cm2 and
our multi-electrolyte separators completely stop dendrites from
forming even at such high current densities,” explained Luhan Ye,
CTO of Adden Energy.
“All-solid-state batteries are one of the most challenging but
also, if you can get it right, the most rewarding directions in
energy storage,” stated Adden Energy co-founder and Chairman at
Harvard, Xin Li. “Adden Energy has developed an unparalleled
solution. The significance of simultaneously maintaining commercial
level cathode loadings, a lithium metal anode, room temperature
operation, and 10-minute charge cannot be overstated.”
