Electricity may seem invisible, but storing it in batteries has some very physical effects. As a battery is charged and discharged, electrons and ions rush around from place to place, sometimes causing electrodes to change their shapes over time. As researchers experiment with improved electrode materials, it’s critical to get a microscopic view of what… Read more »

Navigant Research releases Leaderboard Report on lithium-ion battery manufacturers
In a new report, Navigant Research profiles 11 Li-ion battery vendors that are active in the EV market, and rates them on 13 criteria, including systems integration, safety engineering, chemistry performance, geographic reach, manufacturing and product performance, pricing, and overall corporate financial health. According to Navigant, “Li-ion batteries have won the race to be the chemistry… Read more »
Toyota increases production of lithium-ion batteries
Toyota and Panasonic plan to build a new $194-million production line to produce Li-ion batteries, with a capacity of 200,000 units per year.
OXIS Energy bets on lithium-sulfur
Though it may have a stinky reputation, sulfur could set EVs on the path to total ICE replacement if energy-dense, low-weight lithium-sulfur batteries become the norm. British-based OXIS Energy is banking its business on it. If American clean energy industries are to take full advantage of the emerging lithium-sulfur (Li-S) battery chemistry, they just may… Read more »
Researchers discover memory effect in Li-ion batteries
Scientists at the Paul Scherrer Institute (PSI) and the Toyota Central R&D Labs have reported a memory effect in lithium-iron phosphate (LiFePO4) batteries that appears after only one cycle of partial charge and discharge. Memory effects are well known to users of nickel-cadmium and nickel-metal-hydride batteries. If these batteries are recharged repeatedly after being only partially… Read more »
Toyota to recycle used NiMH batteries into electricity management systems
By improving the usage efficiency of electricity – for example, by cutting the amount used during peak usage times – the new system can cut the cost of electricity and gas used by half
Honda reuses rare earth metals from batteries, releases Environmental Annual Report
In the spirit of the “triple bottom line” (People, Planet, Profit), Honda released its 2012 Environmental Annual Report today, documenting the CO2 emissions of the company’s vehicles throughout their entire life cycles. The company claims to be the first automaker to do so. Honda also announced that it will begin reusing rare earth… Read more »
Cabot launches new performance additive for lithium-ion batteries
The Boston-based specialty chemical company announced the launch of the new LITX50™ carbon conductive additive, designed to increase the power and energy of lithium-ion batteries.
Researchers use MRI to get an inside look at a lithium-ion battery in action
The developed methods could be a powerful set of tools for various aspects of battery development and testing.
Swapping addictions: trading oil for lithium
Although options other than lithium exist, some form of lithium chemistry is at the heart of every EV remotely close to production. Are we at risk?
