Lithium-Sulfur – Better than Lithium-Ion Battery?

A Silicon Valley startup is claiming a new electric vehicle battery – LytCell EV lithium-sulfur (Li-S) battery is designed to deliver three times the gravimetric energy density of conventional lithium-ion (Li-ion) batteries (claimed potentially at 900 Wh/kg). Moreover it also claims to outperform solid state batteries.

Whether this is a genuine breakthrough or just another silly-CON (Do you know the ways of San Jose? Privately held until the IPO?) remains to be validated by vehicle use on the road and ultimately adoption by major automakers. Lyten expects full production and market availability for ‘25-‘26 model year vehicles.

Lyten’s Battery Claims:

  • Will be safer in vehicles than conventional Li-ion batteries because Li-S does not contain oxygen from metallic oxides, which is what drives thermal runaway events (pr obfuscation for fires) that have afflicted many EVs.
  • It is better for the environment with the lowest carbon footprint of any EV battery.
  • They can be produced in cylindrical, pouch, and prismatic formats.
  • It delivers better temperature performance and faster charging.

Lyten Sulfur Caging is the technology used in LytCell batteries to achieve the performance potential of sulfur by arresting the so-called ‘poly-sulfide shuttle,’ a cycle-life compromising factor that so far prevented practical Li-S use in battery electric vehicles. Under Department of Defense (DoD) test protocols, a LytCell prototype design has demonstrated greater than 1,400 cycles, it’s claimed.

“We’re confident that Lyten’s breakthrough battery platform will accelerate the mass consumer adoption of electric vehicle ownership due to the performance, range, and safety improvements of our LytCell EV batteries,” claimed Dan Cook, CEO and a Co-Founder of Lyten.

Additional Claimed Benefits

The Lyten battery platform will offer other advantages to automakers and their end users it’s claimed:

  • Below internal combustion engine (ICE) cost parity
  • Safe and effective operation in environments as cold as -30 degrees Celsius to as high as 60 degrees Celsius enabling reduced system-level costs
  • Flexible and scalable pack sizing, enabling Lyten to accommodate the unique needs of a wide range of automotive platforms
  • Can be produced in cylindrical, pouch, and prismatic formats
  • On-shore cell manufacturing facilities proximate to OEM’s
  • Extended range and/or increased payloads
  • Faster charge times of less than 20 minutes
  • Better for the environment with the lowest carbon footprint of any EV battery
  • No conflict minerals
