What about the emissions involved in mining lithium, making the batteries, dealing with the batteries once they're exhausted, and in generating the electricity. Also, what about the emissions involved in building and maintaining the road infrastructure?

Necessary and solvable (if we've decided cars as a transportation method are here to stay, which appears to be the case in most countries). Lithium is evaporated in ponds, transport of which can move to electric. Lithium batteries can be recycled. All heavy vehicles (including for road infra work) can be electrified. Electricity is ubiquitous, and batteries will only decline in cost. This is not my opinion, these are facts.

As long as we keep ramping battery and renewables production, we'll get ahead of the emissions. To reduce emissions, you must displace combustion in all its forms, and destroy demand for fossil fuels. Renewables push out coal and natural gas on the grid, utility scale batteries push out natural gas due to price volatility (hat tip to Saudi Arabia on their current efforts to destroy the US fracking industry through pumping at full capacity, utilities desperately require stable prices for their fuels which is unlikely to happen if shale production declines due to low oil prices, which will prompt more rapid battery uptake), cheap/clean energy drives demand for EVs due to lower cost per mile than internal combustion (EVs are roughly half the cost per mile to operate as an internal combustion vehicle).
