Characteristics of R767
Following the advantage competitive of marketing, Li-ion product requests the higher LiCoO2 performance. Especially, safety performance has been regarded. LiCoO2 with bigger size are the main stream in international market (with excellent performance). Our company uses special craftwork "T" to process the product. Therefore, our company has researched a new product, which named R767, with a bigger size, excellent safety and electrochemical performance.
Product Performance
1. High tap density, D50 bigger size, Small BET area surface.
2. Diameter distributing equality, BET surface area well, Single crystal structure, High crystallinity.
3. Excellent electrochemical performance, High capacity, Rate of holding capacity
4. Machining & Security of battery well
