Electrovaya-Litarion introduces new 44 Ah lithium ion cell
The new LITACELL LC-44 has 10 % more capacity in the same volume and weight when compared to the old 40 Ah cell.
“The LITACELLTM LC-44 with its higher energy density, delivers 44Ah in the same geometry as the 40 Ah LITACELLTM LC-40. The new model LC-44 is available to OEMs and battery pack integrators worldwide and first deliveries will be made this quarter, Q4 FY2016.”
Let’s see the characteristics of this new 44 Ah cell:
- Max. charge: 4 C (12 minutes charge)
- Max. discharge: 10 C
- Gravimetric energy density: 165 Wh/kg
- Volumetric energy density: 346 Wh/L
- Voltage (Max, Min, Nominal): 4,2 V, 3 V, 3,65 V
- Dimensions (W×L×D): 155 × 249 × 12 mm
- Cycle life: up to 9.000 cycles, 1 C/1 C at 100 % Depth of Discharge (DOD)
It’s obvious that the energy density of this NMC cell isn’t amazing but the power density and the cycle life are great.
We can charge it from 0 to 100 % in 12 minutes or 9,6 minutes to charge from 0 to 80 %.
The chart above shows us how much fast charges and discharges affect the cells lifespan.
Litarion’s Chief Technical Officer, Dr. Joerg Reim said:
“Our strong research team has an exciting program to continuously develop the next generation of lithium-ion cells. The increased energy density of the LC-44 reduces material and other production costs while giving higher energy capacity in the same volume and same geometrical package as the LC-40. Lithium Ion Cells have cost, cycle-life and safety challenges and the LITACELLTM LC-44 provides the break-through technology to address some of these challenges.”
The energy density improvement is not only important to increase electric cars range, since they have limited space available for the battery, but also for cost reduction. Same raw materials for more energy capacity or less raw materials for the same capacity.
Litarion’s Manager, Business Development, Dr. Pia Kuesgens said:
“LITACELLTM 44Ah cells are now available to customers in Europe, North America and elsewhere, where the market demands highest safety and lowest holistic cell costs.”
These cells are build by the German company Litarion GmbH that is fully owned by the Canadian Electrovaya Inc., this explains why Europe and North America are the most expected customers.
While Dr. Kuesgens said:
“We believe this technology should become the industry standard for the Electric Mobility and Energy Storage markets.”
Since the energy density isn’t great we’ll probably see these cells used more frequently in energy storage systems than in electric cars.
