Kilowatt Labs Announces 62% Increase in Energy Density of Gen4 Supercap Cell
Kilowatt Labs, Inc. has released its Gen4 Supercap cell for commercial deployment and has started transitioning its product portfolio to the new cell, as well as initiated development of new products for EV, high-voltage and consumer market segments.
According to Mr. Waseem Qureshi, Co-founder, CEO and CTO, ‘the new cell is prismatic, with an energy density of 130Wh/kg, which is a 62% increase over our Gen3 cells released in 2018. To put this into perspective, a Li Ion cell must have an energy density of about 200Wh/kg to deliver the same performance as our cell (because of no cyclic degradation, full capacity availability and no temperature compensation). Tesla’s new 2170 cell is around 250Wh/kg (so we are getting close).”
The prismatic design and increased energy density have significantly reduced cell manufacturing costs, which enables the Company to reduce product cost and remain cheaper than Li Ion and Lead Acid batteries – both of which achieve pricing economies because they sell in significant scale of hundreds of gigawatt-hours per year. Other important features of the new cell include (a) high charge / discharge speed – the prismatic design enables terminals that can withstand very high currents, allowing for charging / discharging speed of under 6 minutes for a full charge / discharge and much higher speeds for short durations (these charge / discharge speeds are not possible in Li Ion cells) (b) no soldering required to manufacture packs – which saves significant pack production time and reduces the Lead inside each module making them even more environmentally friendly (c) less complex control algorithms (d) vibration proof.
