In the future, semi-solid lithium batteries will become the emerging standard in the lithium battery industry. Compared with traditional lithium batteries, the cost of semi-solid batteries is 40% lower than that of lithium batteries, and the production process is shortened by one-third. Semi-solid lithium batteries are more stable and have fewer technical problems. In terms of density, semi-solid batteries are even twice as dense as traditional batteries, allowing electric vehicles to run longer range and even power aircraft.
The main raw materials for semi-solid-state batteries:
1. Active material (absorbs and releases lithium ions, helping to store energy)
2. Adhesive that makes the slurry adhere more easily to the metal foil
3. Solvents that make the slurry easier to use
On the other hand, the new batteries do not require adhesives and solvents. Existing production processes involve coating a metal foil with a slurry obtained by liquefying binders or solvent solutions, followed by drying. The volume of the slurry decreases during drying, and it cannot be coated too thickly due to limitations in the process.
In contrast, the innovative lithium-ion battery design eliminates the need for adhesives, allowing for a denser slurry. This not only streamlines production but also enhances the overall efficiency of the battery manufacturing process. By optimizing this aspect, manufacturers can achieve significant improvements in battery performance and reliability.
