Been watching this company for a while. They manufacture pretty amazing supercapacitors. looks like their Gen4 supercaps are achieving energy density close to Lithium Ion.

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.

Kilowatt Labs has deployed development resources to launch its mobility storage products that delivers acceptable range with exceptional charging speed. The Company announced that it expects to complete its development in the near term, with significant progress already been made in production of prototypes for EV’s, e-bikes and small carrier trucks, as well as high-speed charging stations. By the end of 2020, it expects to be starting road testing. According to Mr. Waseem Qureshi, co-founder, CEO and CTO of Kilowatt Labs, “our new Gen4 supercap cell, in prismatic form and with energy density approaching that of Lithium Ion, allows us to develop products for the EV industry, with unheard of charging capability and range. I am confident that we will generate significant interest from automakers when we launch our products in early 2021”. Supercap storage is ideally suited to replace chemical batteries in the automotive sector because of its ability to be charged rapidly without affecting cycle life. Lithium Ion degrades, with every charge / discharge cycle, but its rate of degradation increases when charged rapidly. Finally, Kilowatt Labs’ Sirius supercap storage is the only supercap storage product that does not operate in hybrid mode with chemical batteries, which is the conventional way of deploying supercaps. Sirius supercap storage is standalone and completely replaces chemical batteries.

If true, this sounds very promising and may well be a game changer in power storage.

I read the article posted previously. This is indeed a potential game changer for EVs, as a five minute charge is less time than filling up with gas (petrol)!

Yep, Ive been following Kilowatt Labs for about 5 years. The trick seems to be getting the capacitors to discharge slower rather than how they usually function, fast charge and fast discharge. Truly will be  game changer. They are close now to the same energy density as Lithium Ion.
