Shanghai Metals Market. BYD Auto will begin production of a new high-energy density battery in 2015 and apply them in its vehicles, according to board secretary Wu Jing-sheng, as cited by China’s Securities Times. BYD reportedly plans to add manganese to its lithium iron phosphate cathode material to improve the range of electric vehicles and reduce costs.
As one example of the potential benefit of such a cathode material, Dow Energy Materials (DEM) offers a lithium-manganese-iron-phosphate cathode material (LMFP) which provides a 10 to 15% increase in energy density in battery cells compared to standard lithium iron phosphate cathode material (LFP).

The DEM material, which offers the safety and cycle life of iron phosphate chemistries, has an energy density in the 150+ Wh/g range, according to DEM.
