Currently, the highest projected energy density is associated with lithium-air batteries, which could potentially achieve an energy density of around 1200 Wh/kg. This is nearly four times higher than the typical energy density of lithium-ion batteries and is considered the highest projected energy density among next-generation battery technologies.
Among rechargeable batteries that have been manufactured and tested, Chinese researchers have achieved a record-breaking energy density of over 700 Wh/kg using lithium-ion batteries with a high-capacity lithium-rich manganese-based cathode and an ultrathin lithium metal anode. Additionally, a company called Talent New Energy has unveiled a solid-state lithium battery with a reported real-world energy density of 720 Wh/kg.
Here is a summary of these technologies:
| Technology | Energy Density (Wh/kg) |
|---|---|
| Lithium-Air Batteries | ~1200 |
| Chinese Lithium-Ion | >700 |
| Talent New Energy Solid-State | 720 |
These advancements in battery technology are crucial for applications requiring high energy density, such as electric aviation and long-range electric vehicles.
