One of the most sinking feelings any driver has is when they get into their car, switch on the ignition, and – the battery is dead. No matter what they do, they cannot get the ignition to work. The person knows they need to jumpstart their car, they know they should have bought that portable…
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…
Battery technology has had to change and develop over the years to keep up with modern technology, such as drones. Semi solid battery, have been known as its high energy density, have been designed and developed to suit high technology appliances today. UAVs and VTOLS, such as those used in agricultural spraying, robotics, for rescue…
Grepow is at the forefront of the battery market with the development of their advanced, semi solid battery technology. This new product range is more reliable than conventional battery technology and, more importantly, it is lighter in weight and delivers extended endurance. The aim in designing the semi solid state battery has been an imperative driven…
Who hasn’t faced the unfortunate situation where their car battery dies and there’s nobody to help. In such a difficult time you wonder why they haven’t invented a solution. The good news is that there’s a solution – a portable car jump starter. There was a time when car jump starters used to be heavy…
The world needs more electricity, preferably in a clean and renewable form. The energy storage market currently consists mainly of lithium-ion batteries. But what can we expect in the coming years? Let’s start with some battery basics. A battery pack consists of one or more cells, each with a positive electrode (cathode), a negative electrode…
The voltage of LiHV battery 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….
After 6 months with this printer I will give it a Hell Yeah! When you need a solution but dont have the unlimited resources of corporate america you have to take some chances. This was my chance at getting some large parts printed without spending crazy money. It almost seemed silly thinking it could work…
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…
This is a general and most asked question in the globe. We usually purchase lithium batteries and expect them to last for the desired period. The estimated life of lithium batteries is about two to three years of about 300 to about 500 charge cycles. But sometimes, this might not be the circumstance the lithium…
