Li (NiCoMn) O2 batteries, with their lighter weight and longer mileage, appear to be gaining an upper hand in their competition with lithium iron and phosphate batteries for use in electric cars.
Dongfeng Travel Bus Company recently purchased 500 electric buses featuring the Li (NiCoMn) 02 battery by Skio Matrix, an electric car maker in China's Zhejiang province. It has potential plans to acquire another batch by the end of the year, and as many as 10,000 by the end of 2015.
The major appeal of Skio Matrix's Li (NiCoMn) O2 battery is shadowed by lingering safety concerns, despite its performance boost.
The competition between the two types of batteries has been ongoing for years, with BYD employing lithium, iron and phosphate batteries for their thermal stability and safety. Tesla and Nissan have joined the Li (NiCoMn) O2 battery camp for performance.
Safety concerns for the alternative lithium ion battery have been lessened in recent years, thanks to the growing popularity of Tesla cars. The battery received a strong boost further from a joint notice issued by the Ministry of Finance, the Ministry of Industry and Information Technology and the Ministry of Science and Technology setting the energy density goal for electric car batteries at the minimum of 180Wh/kilo. The Li (NiCoMn) O2 battery is the only existing battery capable of meeting the requirement.
Recent converts include JAC, Chery, BAIC and Zotye, all of which will be packaging the battery in their latest models during Auto China 2014 in Beijing.
