A silver oxide battery
Silver oxide primary batteries account for 30% of all primary battery sales in Japan (64 out of 212 million in February 2020).[3]
Large silver oxide batteries were used on early ICBM's and satellites because of their high energy-to-weight ratio. For example the

Mercury content
Until 2004, all silver oxide batteries contained up to 0.2% mercury, incorporated into the zinc anode to inhibit corrosion from the alkaline environment.[7] This corrosion would occur regardless of whether or not the battery was providing power, making shelf life an important consideration with silver oxide batteries. Sony started producing the first mercury-free silver oxide batteries in 2004.
