– Heavy EVs (buses & trucks)
– Electric aircraft
BENEFITS
– Higher specific energy
– Low capacity fade
– Low cost
– Low cost
MEETING THE DEMANDS OF TOMORROW
LIGHTWEIGHT
Systems using metallic lithium are known to offer the highest specific energy, even more so when coupled with sulfur. Sulfur has a high theoretical specific energy of 2,700 Wh/kg, which is 5 times higher than a traditional lithium ion battery. Therefore, for the same energy stored, the batter is significantly lighter.
ENVIRONMENTALLY FRIENDLY
The graphene-sulfur cathode utilizes sulfur instead of heavy metals such as cobalt and nickel which have a significant environmental impact.
