South Korea’s LG Chem plans to start production at its US car battery factory in the second half of this year, two executives told Automotive News. The Holland, Michigan manufacturing plant drew some unpleasant publicity in February, when a DOE investigation found that the production line at the plant was idle, but workers were being… Read more »
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 »
This week brought exciting news for fans of measuring current through resistive shunts. Sendyne Corp. has announced the new SFP100, a high precision current sensing IC that extends the range of accurate current measurements by at least an order of magnitude. With the Sendyne SFP100, ultra-low resistance and low-power consumption shunts can now be used… Read more »
Researchers from the Korea Advanced Institute of Science and Technology (KAIST) have discovered a means to extend the lifetime of lithium-air (Li-air) batteries, a technology that offers the promise of higher energy densities than those achievable with conventional lithium-ion batteries. They report their findings in the February issue of the journal ChemSusChem. Li-air batteries are… Read more »
A report from technology advisory firm Lux Research predicts that new battery technologies will become strong competitors with existing lithium-ion technology by 2020, and that solid-state batteries will surpass Li-ion by 2030. However, consumer electronics, not electric vehicles, will be the market driving the advances. “While much of the motivation for next-generation batteries – whether… Read more »
Their novel approach offers an advantage in terms of safety and also results in a broad (5 V wide) electrochemical window.
(This article originally appeared in Charged Issue 6 – JAN/FEB 2013) AllCell Technologies’ new phase change thermal management material If you have spent time at any of the EV industry trade shows, you’ve probably heard the term thermal runaway. It refers to a chain reaction in which an increase in temperature causes further increases in temperature and uncontrollable… Read more »
