LIYUAN advanced prismatic battery cells
LIYUAN Battery Co., Ltd is a Chinese battery cell maker that produces some of the most advanced prismatic LIBs (Lithium-ion batteries) available today.
Let’s see some of those advanced battery cells.
First, a LFP battery cell comparison.
These lithium iron phosphate (LiFePO4) battery cells – also called LFP – have low energy density, but compensate with high power density (high charge and discharge C-rates), safety, cycle life and are cobalt-free.
Secondly, let’s see a NCM battery cell comparison.
While it’s true that later this year Samsung SDI will replace that 94 Ah battery cell with a 120 Ah version for the BMW i3, it’s interesting that the Chinese battery cell maker LIYUAN already has a more energy and power dense alternative. Nonetheless, this comparison is a bit dishonest since the real Samsung SDI 94 Ah battery cell specs are better than what is presented here.
Anyway, with this NCM 135 Ah battery cell, the BMW i3 would have a 47,43 kWh (96 x 3,66 V x 135 Ah) battery, enough for more than 160 miles (257 km) of realistic EPA range.
Summing up, it’s evident that it won’t take much longer until the Chinese battery cell makers go after the current dominant players (Korean and Japanese). They just need to localize production and open battery plants where they are needed (Europe and North America). However, it’s understandable that Chinese battery cell makers such as CATL, BYD, Lishen and LIYUAN are still focused in their domestic market, since it’s huge and every battery cell they produce is bought.
