France recently set up a new company dedicated to the further design, development and production of lithium-ion batteries than the current widespread use of lower cost, longer life, faster charging sodium ion batteries, is expected to start from 2020 industrial produce.
It is understood that the technology startup called T iamat is the winner of the 'i - L ab' National Laboratory for Innovation in France in 2007 and its R & D project is based on the world's first industry-standard 18,650 Lithium Ion Battery Prototype 1 8 6 5 0 The battery is cylindrical, 65 mm high, and has a cross-section of 18 mm in diameter. Lithium-ion batteries are currently used in notebooks, LED flashlights and electric vehicles.
At present, the company already has dozens of 18650 prototype sodium ion batteries, the future will continue to improve performance and better meet the battery charging speed and battery life of electric vehicles. The company plans from 2020 Officially started production.
Sodium ion batteries and lithium batteries work on a similar principle, its biggest advantage is the rich reserves of raw materials, low prices, better security, especially for storage and air transport. Sodium ion battery research began in the 20th century, around the 80's .201 5 January 2011, the French research team announced the first to achieve a major breakthrough in the development of rechargeable sodium ion battery materials.
According to the information provided by the National Science Research Center of France, the energy density of the 18,650 sodium-ion battery designed by the team is 90 watts per kilogram, which is equivalent to that of the early lithium batteries, and the working life is much higher than that of the existing lithium batteries , Can achieve more than 2000 cycles charge and discharge.
