Investment rationale
As electric vehicles are reaching cost parity, sales are expected to increase exponentially from 3 million units in 2020 to more than 60 million by 2040. And as automakers are already ramping up their EV production, the battery industry is scaling at never seen before rates. To meet sustainability targets, battery cell production needs to grow by ten times its current volume this decade while reducing the cost by more than 40 percent, without sacrificing quality and consistency. As a battery pack is only as strong as its weakest cell, automotive OEMs frequently build 10% extra cells into battery packs to reduce the risk of lower performance. Still, undetected process issues cause poor in-field reliability.
Liminal is providing better data and analytics in EV battery manufacturing. Their advanced inspection and analytics platform Echostat combines ultrasound with machine learning to provide visibility inside batteries throughout the manufacturing process. EchoStat identifies issues when the error occurs, reducing scrap and costs while increasing the overall quality of cell production. This allows customers to catch and resolve design or production flaws in real time, quickly improving quality and productivity and minimizing the exposure to defects. In addition, measuring in real time whether production steps have been completed leads to faster production time, higher equipment utilization rates, and lower cell cost.
Competitive advantage
In the complex world of battery manufacturing, Liminal’s approach to inspecting battery cells is game-changing. They are the only in-line, high-speed ultrasound inspection solution engineered specifically for EV-grade batteries. Inter alia, this helps to improve battery quality and reduce costs as it avoids over-building batteries. Their highly differentiated and high-speed inspection solution empowers battery manufacturers to scale production volumes more quickly and meet cost targets, while ensuring their cells meet stringent EV safety and performance requirements.

No part of this information or the fact that of its distribution should form the basis of, or be relied on in connection with, any contract or commitment or investment decision whatsoever.

The issue and distribution of any information on this website may be subject to statutory or other restrictions in certain jurisdictions. Carbon Equity B.V. requests that individuals taking possession of this information familiarise themselves with and comply with those restrictions. Carbon Equity B.V. rejects liability for any violation of any such restriction by anyone whomsoever, regardless of whether that individual is a potential investor. This website in itself does not entail any offer of any security or an invitation to make an offer to purchase any security to any individual in any jurisdiction where such is not permitted according to the applicable law and regulations.

The Funds of Carbon Equity B.V. will only be offered to potential investors at a later stage pursuant to fund documentation to be prepared and distributed by Carbon Equity B.V., through a dedicated account environment and clearly indicated as such. Any person should note that the Carbon Equity B.V. Funds will eventually exclusively be offered by Carbon Equity B.V. to potential investors in permitted jurisdictions who commit to an initial investment of at least EUR 100,000 or fall under other applicable exemptions. Carbon Equity B.V. will act as the Alternative Investment Fund Manager (AIFM) of the Funds and will benefit from the Dutch sub-threshold regime, pursuant to article 2:66a of the Dutch Financial Supervision Act (Wet op het financieel toezicht).

As such, the Carbon Equity B.V. will benefit from an exemption from the license requirement and ongoing requirements of the AIFMD. Moreover, no prospectus requirement applies in light of article 1(4)(d) of the Prospectus Regulation. Any Funds and Carbon Equity B.V. will therefore fall outside the scope of supervision of the Netherlands Authority for the Financial Markets (Autoriteit Financiële Markten, AFM) and the Dutch Central Bank (De Nederlandsche Bank, DNB)

Carbon Equity does not make investment recommendations and no communication, through this website or in any other medium should be construed as a recommendation for any security offered on or off this investment platform. Alternative investments in private placements, and private equity investments via feeder funds in particular, are speculative and involve a high degree of risk and those investors who cannot afford to lose their entire investment should not invest. Prospective investors should carefully consider the risk warnings and disclosures for the respective fund or investment vehicle set out therein. The value of an investment may go down as well as up and investors may not get back their money originally invested. Past performance is not necessarily a guide to future performance. An investment in a fund or investment vehicle is not the same as a deposit with a banking institution. Please refer to the respective fund documentation for details about potential risks, charges and expenses. Additionally, investors will typically receive illiquid and/or restricted membership interests that may be subject to holding period requirements and/or liquidity concerns. In the most sensible investment strategy for venture capital investing, venture capital should only be a part of your overall investment portfolio. Further, the venture capital portion of your portfolio may include a balanced portfolio of different venture capital funds. Investments in venture capital are highly illiquid and those investors who cannot hold an investment for the long term (at least 10 years) should not invest.
