How will the recall shape battery

Longer battery runtimes have been the wish of many consumers. http://www.laptop-battery-shop.com.au/sony/sony-vgp-bpl9-battery manufacturers have responded by packing more active material into a cell and making the electrodes and separator thinner. This enabled a doubling of energy density since lithium-ion was introduced in 1991.

High energy density comes at a price. Manufacturing methods become more critical the denser the cells become. With a separator thickness of only 20-25µm, any small intrusion of metallic dust particles can have devastating consequences. Sony, the maker of the lithium-ion cells, which are being recalled, says that on rare occasions microscopic metal particles may come into contact with other parts of the http://www.laptop-battery-shop.com.au/dell/dell-inspiron-1520-battery cell, leading to a short circuit within the cell.

Lithium-ion batteries are nearing their theoretical energy density limit and http://www.laptop-battery-shop.com.au/sony/sony-vgp-bps13-battery manufacturers are beginning to focus on improving manufacturing methods and increasing safety. David Perlmutter, Senior VP and General Manager of Intel’s Mobility Group says, “Right now, the industry is working primarily on improving the manufacturing and reliability of traditional lithium-ion batteries .”

The recall is unfortunate. It’s a huge task that will have a long-term ripple effect. Economists predict a setback in form of shipping delays and higher battery prices. Recycling 10 million lithium-ion packs is no easy task. The roughly 70 million cells in these faulty packs will need to be replaced. Sanyo is the largest manufacturer of lithium-ion and produces 42 million cells per month. http://www.laptop-battery-shop.com.au/sony/sony-vgp-bps13ab-battery follows second with monthly production of 27 million cells and Samsung is at 26 million.

http://www.laptop-battery-shop.com.au/dell/dell-inspiron-1525-battery users will ask, “Are there alternatives to lithium-ion that are safer?” Yes, there are newcomers but experts and industry analysts remind consumers that the traditional cobalt-based lithium-ion powering our laptops and cell phones isn’t likely to be replaced soon.

The newcomers are the manganese and phosphate lithium-ion http://www.laptop-battery-shop.com.au/sony/sony-vgp-bps2c-battery. In terms of thermal stability, these two candidates are superior to cobalt. The cobalt-based cell becomes thermally unstable at 150°C (302°F), a condition that can lead to a thermal runaway in which flaming gases are vented. In comparison, manganese and phosphate can sustain temperatures of up to 250°C (482°F) before becoming unstable .
