The future of both electric vehicles and utility-scale energy storage are depending on lithium-ion batteries because of their high energy-density (which is not important for energy storage, and there aren’t enough lithium reserves for even 4 hours of global electricity energy storage). But battery life is important for both vehicles and especially for energy storage, but now it is far too short for either application. Given the challenges of developing better batteries discussed in Who Killed the Electric Car?, it is foolish to base our nation’s future transportation and energy storage batteries (to store intermittent energy and protect the grid from unreliable wind and solar power).

Given the laws of physics, can the Tesla Semi really go 500 miles, and what will the price be?

Preface: Most people think that electric truck makers need to tell us the specs — the battery kWh, price, performance, and so on — before we can possibly know anything about their truck. But that’s simply not true.  We know … Continue reading

The periodic table limits battery development

[ Since fossil fuels are finite, biomass doesn’t scale up, hydrogen is an energy sink, transportation in the future will need to be electrified, especially trucks, which are the most essential and important part of civilization, responsible for supply chains, … Continue reading

Would Tesla, SolarCity or SpaceX exist without $4.9 billion in government subsidies?

[ Tesla has made no new battery breakthroughs. Batteries aren’t much better today than they were 200 years ago.  All Tesla did was build a better battery management system (BMS) by stringing teeny-tiny batteries together — thousands of them.  But … Continue reading

All Electric Trucks. Probably not going to happen. Ever. Why not?

There are “forms of transport that cannot be electrified — heavy-duty trucks and planes… Even if the electricity problem can be solved, it won’t address the needs of planes, trucks, ships and some industrial heating that cannot be electrified” (Long). … Continue reading

What is the life span of a vehicle Lithium-ion Battery?

How long a lithium-ion battery will last depends on many factors Lithium-ion battery life is defined in studies as beyond its useful life when its capacity falls by 20 percent or more. Lithium-ion batteries start to degrade as soon as … Continue reading

EPA LCA study lithium-ion battery environmental impact, energy used, recycling issues

[ The future of both electric vehicles and utility-scale energy storage are depending on lithium-ion batteries because of their high energy-density (though that is not as important for energy storage, but that’s where most research money is going). This EPA … Continue reading
