  If you scroll through that PDF you'll notice the temperature capacity chart. At -40°C you're going to have to limit your power drain a lot to get rated capacity. At low temperature the chemical reactions get too slow to take advantage of the full capacity of the battery, that's simply a reality you can't get around. A "betavoltaic" would deliver full rated capacity at any temperature, regardless of changes or duration.
