Lithium batteries are hazardous materials and are subject to the Department of Transportation’s Hazardous Materials Regulations (HMR; 49 CFR Parts 171–180). What are the hazards of lithium? ► Exposure to Lithium can cause loss of appetite, nausea, vomiting, diarrhea and … Continue reading →

As we’ve already known that Lithium-ion cells or other cells are measured in ampere-hours (Ah). To put in perspective, what one ampere-hour means is that you can derive one ampere from the battery cell over one hour. Therefore, the ampere-hour … Continue reading →

The most common battery type in modern electric vehicles are lithium-ion and lithium polymer, because of their high energy density compared to their weight. Are car batteries lead or lithium? The vast majority (nearly all) car batteries are some form … Continue reading →

All lithium-ion batteries contain a flammable electrolyte that can short circuit, catch fire, and explode. Something as simple as a rechargeable battery cell charging too quickly could cause fire hazards. Despite stringent testing requirements, battery-related fires still occur. Is it … Continue reading →

Lithium-ion is perhaps the most powerful battery type available, but it comes with a risk called thermal runaway — when defects or mishandling causes a battery to overheat and explode. If a battery were to catch fire inside a pressurized … Continue reading →
