Svolt Energy Technology, a major Chinese manufacturer of batteries for electric vehicles, has unveiled what it says is the world's first cobalt-free battery, which has been mass-produced. Such batteries will be used in the Great Wall ORA Cherry Cat electric vehicles, which will be unveiled at the Chengdu Auto Show this year. Cobalt-free battery vehicles are expected to go on sale in China.
The manufacturer said that the battery "lightweight design uses modules of the standard MEB platform and thermal insulation materials of the aerospace level." The battery has passed extensive testing, including safety tests, and the results obtained exceed the requirements of national standards. The battery has an energy density of 170 Wh / kg. Its capacity of 82.5 kWh under normal temperature conditions is enough for an electric car to travel more than 600 km. Load capacity allows you to accelerate from 0 to 100 km / h in less than 5 seconds. The battery protection rating is IP67. In addition, the battery is said to retain its capacity well and warms up quickly in low temperatures.
The development of the battery took several years. Now the product is completely ready for mass production.
The desire of manufacturers to remove cobalt from batteries is due to the fact that world reserves of this metal are limited to about 7.1 million tons. The growth in consumption has already led to a significant increase in the price of cobalt, and its shortage is expected in the coming years, which will become a serious constraint for the development of the electric vehicle industry.
