DESCRIPTION

　　1 Introduction

　　2. Model: HLM-105

　　3. Scope of application of the product

　　It is suitable for high rate and high energy density products, such as electric tools, electronic cigarettes, electric bicycles, two-wheel vehicles, tricycles, small energy storage and other fields.

　　4. Product Features

　　The production of this product adopts the process of element doping and particle size recombination. It has the advantages of high compaction density, high specific capacity, good cycle performance, good consistency, and good processing performance. It can greatly reduce the cost when used with ternary.

　　(1) The product particles are complete and regular spinel phase, the particle size distribution is uniform and concentrated, and the material processing performance is superior.

　　(2) The comprehensive performance of the product is excellent. The normal temperature 1C gram capacity is greater than 118mAh/g, the cycle is more than 500 cycles, and the capacity retention rate is greater than 80%.

　　(3) There is no impurity phase in X-ray diffraction.

　　6. Packaging and storage conditions

　　6.1. Packing method: Inner aluminum foil bag, vacuum packaging, outer carton, 25kg/box.

　　6.2. Requirements for stacking layers: carton packaging ≤ 3 layers.

　　6.3. Label style: the default Haili lithium battery shipping label, if the customer has special requirements, it can be implemented according to the label style provided by the customer.

　　6.4. Storage conditions: Keep sealed and avoid direct sunlight. The recommended storage temperature is ≤37°C and the humidity is ≤50%RH. The shelf life is 1 year. If the product exceeds the shelf life, it should be inspected by our company and re-evaluated whether it can be used normally.

　　6.5. Under the condition of unsealing, strictly control the storage humidity to ≤30%RH, and use it as soon as possible.

　　7. Precautions for transportation

　　When loading, do not place heavy objects on top of the cartons to prevent deformation of the cartons; prevent extrusion and sun and rain; use vehicles, trains, ships, planes and other vehicles for transportation.

　　8. Suggestions for processing and use

　　Positive electrode ratio: lithium manganese oxide 95.0%~96.5%, SP0.3%~0.5%, CNT0.6%~1.2%, PVDF2.6%~2.9%. It is recommended to use PVDF with a molecular weight greater than 1 million as the binder. If the binder is made by the suspension method, the dosage can be adjusted to 1.5% to 2.0%.

　　Suggested negative electrode excess ratio: 8﹪～12﹪.

　　It is recommended to use compaction: 2.80～2.90g/cm3.
