Energy Density
- Solid-State Batteries: These batteries have a higher energy density, typically ranging from 500 to 700 Wh/kg. They can store up to twice as much energy as lithium-ion batteries, especially when advancements like replacing the anode are considered.
- Lithium-Ion Batteries: Lithium-ion batteries have a lower energy density, usually between 250 and 300 Wh/kg. This means they require more space to store the same amount of energy compared to solid-state batteries.
Charging Speed
- Solid-State Batteries: They offer faster charging times, with the ability to reach 80% charge in as little as 10 to 15 minutes. This is significantly faster than lithium-ion batteries.
- Lithium-Ion Batteries: Typically, lithium-ion batteries take anywhere from 20 minutes to several hours to fully charge, depending on the charging method.
Lifespan and Durability
- Solid-State Batteries: Solid-state batteries can endure more charge cycles, typically lasting between 8,000 to 10,000 cycles. This means they have a longer lifespan and can last up to 100,000 miles in electric vehicle applications.
- Lithium-Ion Batteries: In contrast, lithium-ion batteries generally last for 1,500 to 2,000 charge cycles and have a shorter lifespan, typically up to 60,000 miles in EVs.
Cost and Environmental Impact
- Solid-State Batteries: Currently more expensive than lithium-ion batteries, with a cost per kWh ranging from $800 to $1200. However, they use fewer materials and could reduce climate impact by up to 39% compared to lithium-ion.
- Lithium-Ion Batteries: Cheaper, with a cost per kWh between $100 and $150. However, they require more materials and have a higher environmental footprint compared to solid-state batteries.
Overall, solid-state batteries are more energy-efficient due to their higher energy density, faster charging capabilities, and longer lifespan. However, they are currently more expensive and still in early development stages compared to widely available lithium-ion batteries.
