Considering a couple of factors: Li-metal batteries are not re-chargeable and are often used in long term applications (10-15 years) like pacemakers and other medical implants where they typically outlast the component they power. The "coin" style ones in calculators, watches, key fobs, clocks, cameras etc. usually last many years before they need replacement.
Additionally, just about every laptop, tablet and smart phone uses the Li-ion variety and many of those items are replaced by consumers far more frequently. So, as a complete guess - I would assume Li-ion shipments are much higher (if you include not only bulk shipments of batteries alone, but also those installed in bulk shipments of personal electronics).
