CELLARK
"Revolutionising Lithium Batteries with advanced Silicon Anodes"
Cellark has developed and pioneered porous silicon anode material production which is scalable and cost-effective. With Porosil technology, the lithium batteries can have 100% energy density improvement over the current, state-of-the-art, lithium batteries.
" The way forward to increase the lithium battery energy density is improving anode material by systematically replacing it with Si. "

About Us
Cellark has developed the next generation silicon anode material for lithium batteries which boasts 30% more energy density than the conventional graphite anode-based lithium batteries.Cellark uses easily available Al-Si alloys for porous silicon production and its proprietary technique to stabilize it and make it suitable for battery application. The porosil technology is the result of 10 years of research and development work in the labs of IIT Bhubaneswar. We have developed a silicon graphite composite anode that can directly replace the current graphite anode without impacting the life of the battery.

30% higher energy density
Taking advantage of high silicon energy density the cell developed with porosil anode material provides much higher capacity in the same volume than the graphite anodes, our porosil anode gives >550mAH/gm of energy density.

>15% volumetric expansion
Silicon anode suffers from huge volume expansion which reduces the life of the battery. Our innovative porosil anode solves this problem with our porous silicon morphology. The crux of the innovation lies in the science of selective leaching of Al-Si and its galvanic coupling.

Reliable bonding with graphite
Our proprietary method to produce Si and graphite composite with suitable carbon coating ensures proper bonding of graphite and silicon,thus, higher life of the battery.

>50% less anode material
With the specific capacity increased, the anode material needed to fabricate cells is reduced by 50%, which, further brings down the cost of the cells.
Planned Pilot
Planned Pilot-scale plant for producing Si anode material sufficient for 50 electric car batteries in a month.
