Slurry preparation calculator

The slurry contains active material, conductive agent and binder in solution form, in usual the ratio in weight is 80:10:10 for cathode in research (for anode 90:3:7), but for getting high capacity we need to increase the active material as much as possible. Industries try to optimise the materials for the ratio 93.5:4:2.25. Quality, morphology as well as chemical properties decides the ratio and needs to be optimised for each set of the chemical used. So there is no universal ratio. There are two methods to make slurry, either binder is mixed along with other solids and then finally solvent or the binder is mixed with solvent to make binder solution and then it is added to the solids containing mixture of active material and conductive agent. Preparation of PVDF-NMP Solution; the NMP should be minimum and optimized between the porosity (which forms after NMP leaves the coating) and adhesiveness to the foil. For optimization viscosity of the slurry i...

Cell Capacity Balancing

The cell capacity balancing is done keeping by determining the capacity of anode and cathode. In general, the anode is taken more by 1.1-1.2 times of cathode to avoid lithium metal dendrite formation. The voltage also plays a crucial role in mass balancing.

Capacity of Cathode/Anode

Theoretical capacity of the material is calculated when it transfers one gram of ions. Ionic transfer of Lithium is measured in lithium batteries as so for their counterparts like Na, K or Mg. Lithium is said to be having theoretical capacity or specific capacity of 3842 mAh/g. This value sounds exciting as well as controversy since for this much energy the whole lithium has to move, but in principle only a part of lithium which placed at anode side moves. So how is it calculated and for other materials. ----------------------------------------------------------------------------------------- In general, theoretical capacity of a material is given by: C=nF (Coulomb) where n is the number of electron transferred and F is the Faraday constant. This value has to be divided by molecular weight (MW) of the material for the theoretical specific capacity Csp=nF/MW (Coulomb/g) Since 1 Coulomb = 1Amp-Sec = 1000 mA * h/3600 Csp= 1000/360...

Lithium ion batteries

-----| this whole blog is under construction, for updates keep subscribed |----- A battery is a transducer that converts chemical energy into electrical energy. They are the source of energy which can be stored and also mobile. Batteries which can be used only once are called as primary batteries while which are rechargable and used more than one time are called as rechargeable or secondary batteries. Lithium is used in both primary as well as secondary batteries but the term lithium ion batteries is generally used for secondary batteries. They come in various shapes (coin, cylindrical and pouch) and sizes depending upon the energy density and the area of applications. Developments Recent developments of lithium-ion (Li-ion) batteries based on new and improved chemistries have resulted in batteries with high performance, long lifetime and increased safety. It not only became the ultimate choice for any portable power equipment but also in standalone systems like UPS and energy...

Lithium ion battery - Materials & Components

In general we may state lithium ion (Li-ion) battery as one (or best) among many portable batteries packed with lot of power. It has these common traits which makes it special Small and light (Energy Dense) Long power backup when not used (Low self-discharge) Rechargeable for years (Long cycle life) Reliable and cheap Alternative technologies, (more info) even though looking promising on paper but cannot match Li-ion technology in the foreseeable future. Till these alternative technologies mature the standard of Li-ion is going above with increase in power (energy density) with newer chemistries. Though the cost is seen to increase but dollar/kW will be less. It means we can have the same capacity of battery what we have now at less price and probably even more smaller and lighter. At present there is no replacement for portable rechargeable batteries other than lithium ion and the need for its performance in every area makes it challenging for manufacturers. The need to cre...

Regenerative Braking

Regenerative braking is a technology used in electric and hybrid vehicles that allows the vehicle's kinetic energy to be recovered and used to recharge the vehicle's battery. When a vehicle brakes, it converts the kinetic energy of the vehicle into heat, which is dissipated through the brakes. In a conventional vehicle, this energy is lost and cannot be recovered. In an electric or hybrid vehicle, however, the kinetic energy can be recovered through the use of a regenerative braking system. A regenerative braking system consists of an electric motor that acts as a generator when the vehicle brakes. When the brakes are applied, the motor slows down and generates electricity, which is used to recharge the vehicle's battery. This can significantly increase the range of an electric or hybrid vehicle, as it allows the vehicle to recover some of the energy that would otherwise be lost during braking. Regenerative braking is an important technology for electric and hybrid vehicles...
