Tesla is pushing back against any notion that its batteries are unsafe.
“Serious high-speed collisions can result in a fire, regardless of the type of car,” a Tesla spokesperson said in a statement to ABC News. “Tesla’s billions of miles of actual driving data shows that a gas car in the United States is five times more likely to experience a fire than a Tesla vehicle.”
Are you saying that lithium battery is more flammable than oil & gas?
Battery Research
Research into lithium batteries has accelerated over the past the past ten years with the promise of energy density being quadrupled or even enhanced by a factor of ten. Promising areas of research are for lithium-vanadium-phosphate batteries (also called vanadium redox flow batteries), lithium-sulphur batteries and lithium-air batteries.
Lithium Vanadium Phosphate
The vanadium flow batteries (VFBs) hold enormous promise in battery storage technology and have been touted as the next big thing.
When applied to EVs the higher voltage in this type of battery results in higher speed and acceleration. The energy density of this battery will result in more light weight EVs.
LVP batteries charge faster and also have a higher life expectancy than current lithium-ion batteries.
Lithium-sulphur batteries would increase the energy density of batteries by a factor of four whereas lithium-air would increase the energy density up to a factor of ten.
There are challenges to develop and commercialise both types of batteries.
Lithium Sulphur
Lithium-sulphur batteries have a shorter lifespan than current lithium-ion batteries and can’t be charged as many times. Pacific Northwest National Laboratory (PNNL) announced on 9th Jan 2014 they have developed a hybrid anode for lithium-sulphur batteries that increases the cycle rate of this type of battery by providing a graphite shield around the anode.
Research carried out at Stanford University is providing battery researchers with tools that investigate the way the battery behaves in real time.
Lithium Air
IBM started investigating lithium-air battery technology in 2009 with the Battery 500 Project. There are certainly challenges to develop air breathing batteries but the prize is a battery with the energy density of gasoline. This would extend the range of EVs approximately tenfold.

Solid State Batteries
Solid state lithium batteries present the most potential for breakthrough over the next few years. Density levels in lithium ion batteries (those with a liquid electrolyte) have been improving markedly over the past 20 years (about tripled) but the improvement curve is finite for this type of technology and only so much tweaking can be done. Solid state batteries (no liquid electrolyte) offer much higher energy density than current lithium ion batteries (about double) – have much less fade, they are easier to shape, have no fire risk and don’t swell! Solid state batteries remove much of the complexity built in to today’s lithium ion batteries.
The manufacturing process for solid state batteries is very similar to a number of current industrial processes so there’s no major work to be done on tooling up for manufacture. Because of this, the potential for solid state EV batteries to be introduced over the next two to three years is reasonably high. One particular company developing this technology right now is Sakti3, headed up by Dr. Ann Marie Sastry. There are a number of youtube videos featuring Anne Marie describing solid state batteries.
