What's new in China's Lithium-ion battery industry?

BEIJING, June 19 -- China's Ministry of Industry and Information Technology on Wednesday unveiled revised guidelines for the lithium-ion battery industry to further strengthen standardized management and promote the high-quality development of the sector.

How many MV should a lithium ion cell have?

As most of the cells would fall under 5V range, upto 8 to 10V upper range, measurement capability (resolution of 0.1 mV) and internal resistance measurement range of upto 50-60 milliohms with resolution of 0.1mohm should be sufficient to take care of the entire range of cylindrical Lithium Ion cells.

What is the nominal voltage of lithium phosphate cells?

For lithium iron phosphate cells the nominal voltage is 3.6V and for ternary lithium & lithium manganate cells, it is 4.2V. Because of the use of graphite anodes, the voltage of lithium cells is dependent on the cathode materials.

Should lithium-ion batteries be built on farmland?

No lithium-ion battery projects should be built on permanent basic farmland, "redline areas" for ecological protection or other areas where the construction of industrial enterprises is prohibited, the guidelines state.

What is the self-discharge rate of lithium ion cells?

Generally, the self-discharge rate doubles for every 10°C increase in cell temperature. The monthly self-discharge rate of lithium-ion cells is about 1 to 2% as compared to the monthly self-discharge rate of 10-15% for nickel-based cells. Long life Cycle and calendar life determine the value for money for a cell.

What voltage should a lithium ion battery be tested at?

Lithium Ion Battery Specifications AA Portable Power Corp. 2. 5V Unless otherwise specified, all tests stated in this document shall be performed at 23±2°C. 3. Performance and test conditions Standard charge: 0.5C=1650mA constant current (CC) charge to 3.65V, followed by 3.65V constant voltage (CV) charge until current taper to ≤0.01C。
