It's not a matter of finding them. It's about avoiding unnecessary and non-recyclable waste. A rechargeable Lithuim cell and a non-rechargable one are almost identical internally. There is absolutely no reason why disposable ones are still manufactured. This applies to all kinds of batteries, not just Lithium coin cells.
