Exhibit 99.4

ELECTRA BATTERY MATERIALS CORPORATION

ANNUAL GENERAL AND SPECIAL MEETING OF SHAREHOLDERS

NOTICE-AND-ACCESS NOTIFICATION

You are receiving this notification because Electra Battery Materials Corporation (the “Company”) has decided to use “notice-and-access” for delivery of proxy solicitation materials to its shareholders for its annual general and special meeting of shareholders (the “Meeting”) to be held on Thursday, November 10, 2022. Under notice-and-access, shareholders still receive a proxy or voting instruction form enabling them to vote at the Meeting. However, instead of a paper copy of the management information circular of the Company dated September 28, 2022 (the “Circular”), as well as the annual audited financial statements and the management’s discussion and analysis (collectively, the “Meeting Materials”), shareholders receive this notice with information on how they may access the Meeting Materials electronically through a website and under the Company’s SEDAR profile. This process directly benefits the Company through a substantial reduction in both postage and material costs and also helps the environment through a decrease in paper documents that are ultimately discarded. Under notice-and-access, proxy-related materials will be available for viewing for up to one (1) year from the date of posting, and a paper copy of the Meeting Materials can be requested at any time during this period.

While as of the date hereof, we are intending to hold the Meeting in a physical face-to-face format, we are continuously monitoring the coronavirus (“COVID-19”) situation. In light of the rapidly evolving news and guidelines related to COVID-19, we ask that, in considering whether to attend the Meeting in person, shareholders follow, among other things, the instructions of the Public Health Agency of Canada (https://www.canada.ca/en/public-health/services/diseases/coronavirus-disease-covid-19.html) and any applicable additional provincial and local instructions. You should not attend the Meeting in person if you are experiencing any cold or flu-like symptoms, or if you or someone with whom you have been in close contact has travelled to/from outside of Canada within the 14 days before the Meeting. All Shareholders are strongly encouraged to vote in advance of the Meeting using the proxy form or the voting instruction form provided to them with the Meeting materials.

You are entitled to vote at the Meeting and any postponement or adjournment thereof if you owned Common Shares (as defined below) at the close of business on the record date of September 28, 2022.

MEETING DATE, TIME AND LOCATION:

Date:	Thursday, November 10, 2022
Time:	11:00 a.m. (Toronto time)

	123 Queen Street W, Toronto, Ontario, M5H 2M9

THE FOLLOWING MATTERS, ALL AS MORE PARTICULARLY DESCRIBED IN THE CIRCULAR, WILL BE REVIEWED AND VOTED ON AT THE MEETING:

1. To receive the audited financial statements of the Company for the year ended December 31, 2021, together with the report of the Auditors thereon;

2. To appoint KPMG LLP as the auditor of the Company for the ensuing year, and to authorize the directors to fix the remuneration to be paid to the Auditor;

For detailed information regarding each of the above items of business, please refer to Part 2 of the Circular titled “Business of the Meeting”.

SHAREHOLDERS ARE REMINDED TO REVIEW THE MEETING MATERIALS PRIOR TO VOTING. It is important that your Common Shares be represented at this Meeting to ensure a quorum is present. If you cannot be present to vote in person, please ensure that your proxy or, if a corporation, your representative, is appointed and present to vote on your behalf at the Meeting. Instructions regarding the appointment of a proxy or representative are contained in the Circular and in the accompanying proxy or voting instruction form.

WEBSITES WHERE MEETING MATERIALS ARE POSTED:

The proxy-related materials for the Meeting or annual financial statements and management’s discussion and analysis may be viewed online at www.sedar.com under the Company’s profile, or at the following internet address: https://www.ElectraBMC.com/investors/meeting-materials/.

HOW TO OBTAIN PAPER COPIES OF THE MEETING MATERIALS:

If you wish to receive a paper copy of the Meeting Materials, annual financial statements or management’s discussion and analysis or have questions about notice-and-access for the current Meeting, please call the Company’s transfer agent, TSX Trust Company, at 1-888-433-6443 or by email at tsxt-fulfilment@tmx.com. In order to receive a paper copy of the Meeting Materials in time to vote before the Meeting, your request should be received at least five (5) business days in advance of the proxy deposit date and time set out in the accompanying proxy or voting instruction form.
