In addition to the safety deficiencies are in the cycle stability, durability, energy density and the cost of batteries, high-volume streamers in the way. In terms of strength and service life cycles of many manufacturers clean and dry areas are considered essential. How we produce and develop the Bosch-Samsung joint venture SB LiMotive in all production sections under clean room conditions. "All kinds of debris and particles would be the quality and under some circumstances ibm thinkpad z61p battery endanger the safety of cells," said Bosch spokesman Udo Rügheimer. Even at temperatures and humidity to keep a fixed conditions. Exact values he places not open: a trade secret. Same with Johnson Controls. Spokeswoman Ina Longwitz can look through that clean rooms and meticulously monitored humidity in the battery production are standard. But she does not mention numbers. How Rügheimer only confirming that the above values of Nerling move in realistic sizes.
Something more is from Ernst Barenschee, learn to Managing Director at Evonik Litarion Kamenz. In view of the production process, he makes it clear why particles and moisture are taboo. The anodes and cathodes are wafer-thin aluminum and copper foils are coated to a few microns exactly Medion ibm thinkpad z61m battery active paste, then rolled in the calender, dried, before they cut, stacked with separators, then contacted and wrapped airtight. Cleanliness is essential in the first steps in which mixed the powdered active materials and processed with the addition of binders to form pastes. While some components dominate in the mixture, the proportion of other lies in the ppm range. The quality of the cells rises and falls with a homogeneous distribution of these alchemical formulas. Contaminants are taboo.ibm thinkpad z61e battery
Drying rooms are needed, according Barenschee for two reasons: water inclusions could react with the active materials to hydrofluoric acid and thus shorten the life span. In addition, the cost of drying ibm thinkpad r50p battery electrodes freshly coated and rolled the more time and energy, the moister they come into the ovens. Min at today's coating speeds of 20 m / min, it was on the VDMA conference heard, it requires 35 m long drying so that the manufacturing process does not falter.ibm ThinkPad 600 battery
But it is still below 2% relative humidity. Nerling realized in the follow-up project a clean room with a maximum of 0.5%. Medion Battery WIM2180 values, the factory planners of the M + W Group have been implemented. In the cell assembly and filling with electrolyte were humidity below 0.5% already prior art.

-In addition to drying the metrological supervision is challenging. Values below 2% with conventional air humidity undetectable knives. The plant engineers are therefore having to use dew point measurements. Si form at an air humidity of 2%
