The energy density of batteries can be displayed in two different ways: gravimetric energy density and volumetric energy density. The gravimetric energy density is the measure of how much energy a battery contains in proportion to its weight. This measurement is typically presented in Watt-hours per kilogram (W-hr / kg). The volumetric energy density, on the other hand, is […]
Californians do not purchase electric vehicles because they are cool, they buy EVs because they live in a warm climate. Conventional lithium-ion batteries cannot be rapidly charged at temperatures below 50 degrees Fahrenheit, but now a team of engineers has created a battery that can self-heat, allowing rapid charging regardless of the outside chill.
LiHV电池的电压 An L-i-H-V battery is a type of Lithium battery that allows for a higher than normal voltage. The “HV” stands for “high voltage” and it has a higher energy density than standard LiPo batteries. Ordinary LiPo batteries have a nominal voltage of 3.7V and a fully charged voltage of 4.2V. LiFePO4 batteries have a nominal voltage of 3.2V […]
The SEI (solid electrolyte interphase) is formed on the surface of the anode from the electrochemical reduction of the electrolyte and plays a crucial role in the long-term cyclability of a lithium-based battery. Introduction of SEI During the first charge and discharge of a lithium-ion battery, the electrode material reacts with the electrolyte at the solid-liquid […]

10 Tips For More Eco-Friendly Outdoor Adventures & Camping Trips Posted March 31, 2021 The percentage of people that enjoy camping three or more times each year has increased 72% since 2014, according to a recent report, particularly in light of the COVID-19 pandemic and associated international travel restrictions. Between the rapid increase in outdoor recreation […]
NiMH is an abbreviation for nickel-metal hydride. Ni-MH batteries are our most common rechargeable batteries in consumer electronics. Due to its superior chemical properties, nickel-metal hydride batteries have replaced nickel-cadmium batteries. Since NiMH does not use cadmium (the use of toxic chemicals in battery use) and also does not have the same memory problems that plague NiCD, […]
by Emma Foehringer Merchant February 02, 2021 With President Joe Biden in the White House, ink drying on a spate of new climate-focused executive orders and an extension of the federal Investment Tax Credit on the books, the immediate future looks relatively rosy for solar. The U.S. Energy Information Administration anticipates that renewables will be the fastest-growing […]
Your phone is about to go dead—again—and you can’t find a place to plug it in. Your laptop is getting hot…is the battery about to catch on fire? How far from home should you drive your electric vehicle? As scenarios like these become increasingly common, it’s clear that we need batteries that store more, last […]
When I started this hobby the thing that shocked me the most was how short flight times were. 5 minutes??? Sometimes more. Sometimes less. To make matters worse, most people drive to a park or a field where they don’t have access to electricity to recharge their batteries. Yes, you can buy a couple dozen […]
