Lithium manganese oxide powder LMO Mn - 102, with a manganese - based system delivering a 1C capacity of 102mAh/g and a retention rate of over 90% after 100 cycles. It has low metal impurities (Fe/Cu/Zn < 0.02%) and is suitable for portable - device lithium batteries. It's available as 1kg/PE - bagged laboratory - grade material for immediate use.
Lithium manganese oxide powder cathode material (LiMn₂O₄, model Mn - 102) is a cost - effective lithium - battery cathode powder. With a manganese content of 57.7% (standard 56.5 - 58.9%), it has a discharge capacity of over 102mAh/g at 1C, and a tapped density of over 2.0g/cm³. It suits the battery needs of portable electronic devices. By controlling the particle size at D50=13 - 17μm and keeping the specific surface area at 0.4 - 1.0m²/g, it reduces side reactions with electrolytes. It has a capacity retention rate of over 90% after 100 cycles. With strict control of metal impurities (Fe/Cu/Zn < 0.02%) and a weak alkaline pH of less than 11, it ensures stable slurry processing. Packaged in 1kg/PE bag and 25kg/drum, it has a 1 - year hygroscopic shelf life. It's suitable for medium - to - low - rate applications like power banks and electric tools, meeting the core needs of low cost and high safety.

FAQ
Q1: How to improve capacity retention after 100 cycles?
A: It is recommended to pair it with highly stable electrolytes (such as those with LiBOB additives) and use nano - carbon coating technology. This can enhance capacity retention to 95%. Technical guidance can be provided for specific solutions.
Q2: What's the cost difference of lithium manganese oxide powder compared to lithium cobalt oxide (LiCoO₂)?
A: Manganese has abundant reserves. The material cost is about 40% lower than that of lithium cobalt oxide systems. Also, there's no need to comply with regulations on cobalt metal.
Q3: How to extend the shelf life after opening?
A: Seal unused material immediately and store it in a dry box with humidity below 30%. It's advised to use molecular sieve desiccants. This can extend the validity period to 18 months.
Q4: Is electrode compaction of over 3.0g/cm³ possible?
A:The lithium manganese oxide powder is designed for a tapped density of above 2.0g/cm³. For high - compaction needs, it's suggested to select batches with D50＞15μm and optimize the conductive agent ratio.
Q5: How does metal impurity control affect battery self - discharge?
A: With Fe/Cu/Zn impurities below 0.02%, the risk of micro - short - circuits is reduced. Tests show that after 28 days of storage at 60℃, the self - discharge rate is under 5%, surpassing industry standards.
