v81, 10 months ago I’m pretty good with batteries, but I don’t know if I understand the issue. Isn’t the keyboard already rechargeable? If so then why isn’t charging it an option? What are you using the keyboard with? How does that device get power? Is recharging or using a power bank absolutely out of the question? Are you looking for a temporary, semi permanent or permanent solution? Are you strictly limited to common convenience batteries? How about slightly uncommon batteries like cr123?
