Lithium Battery Circular Economy
■ Industry Status
As market size of electric scooter keeps growing, the retirement issues get important. The accumulated waste lithium batteries would be more than 10,000 tons of by 2025.
Currently, 2/3 of the waste batteries are exported outside with the valuable resources. Taiwan urgently needed to develop a lithium battery circular economy to replace the traditional treatment process.
■ Technology Features
• Cathode directly reuse, maintain high structure integrity
• Recycled electrodes designed to reduce impurities at the ppm level through the specific formulation
• AI Smart sorting and EHF fragmentation reduce the contamination, structure damage, and improve battery material recovery rate >93%
■ Benefits
• Redesign + Recycle + Regeneration + Revalue
High Energy Density Lithium Metal Battery Interface Technology-ASEI
■ Industry Status
To react to the global electric vehicle market, lithium battery capacity growing rate is about 17% per year.
However, as the energy density of lithium batteries approaches the theoretical upper limit, the technology of lithium batteries with ultra-high energy are important.
■ Technology Features
• This technology utilizes lithium metal battery as the verification device and introduces an artificial coating onto the surface of the lithium metal anode
－It protects high activity lithium metal and reduced the side reaction caused by the reaction with electrolytes
－It is important to suppress the high risk lithium dendrites
• The high energy battery design was relied on high electrode loading and high density, but it will scarify cycling stability
－The main function of ASEI was to homogenize the ion flow during charging to form a better lithium deposit to achieve a high cycling efficiency
■ Benefits
• Development of critical technologies for the future lithium batteries
• Acceleratting commercialization and product feasibility of lithium metal batteries
• Integrating with the module and system design
Verification Platform of Novel Sodium Ion Batteries
■ Industry Status
Due to high cost of raw materials and high potential risk of exothermal reactions of lithium batteries, the researches and development of sodium ion
batteries have become a hot topic in recent years.
■ Technology Features
Providing a normalized assembling process, electrochemical properties verification instruments and platform to perform systematic verification
against material properties and further propose improvement suggestions.
■ Benefits
• Establishing a systematic verification method against battery module and material design of sodium ion batteries
