homegrown tech company infuses new life into lead acid batteries - small lithium ion battery
A local company, Log 9 Materials, has made technological breakthroughs in the capacity of lead-acid batteries used in cars, inverters and solar storage units.
Akshay Singhal, founder of Log 9 Materials, said in an interview: "What we have been able to achieve so far is a 30% increase in battery storage power . ".
"So, if the storage capacity is 5 hours, then it can run for 6 hours now. 5 to 7 hours. ”Mr.
Singhal added that his company has increased its battery life by 35%.
"The potential for this is to increase capacity by 50% and to increase life by 40%," he said . ".
This breakthrough is an area where the materials used in the last 30 years have not changed, and it is achieved by using a form of carbon called graphene. Mr.
Singhal, a graduate of IIT Roorkie, said that the Log 9 material was originally a manufacturer of graphene and nanoparticles, but quickly evolved into a product manufacturer because "if there is a first product in the market that is graphene, then it makes more sense before the material market picks up.
"Graphene is a very thin material," he added . ".
"As thin as the material, its capacitance (
Ability to store charge).
Graphene is a single-layer atom tightly placed together.
This is the thinnest you can get.
It is also very attractive, so you can not only store more fees, but also extract them at a higher price.
"For example, if a battery can run four fans at a time and then start running 10 fans, it will run, but it ran for two hours earlier, it will be discharged in 30 minutes now.
In addition, the repeated full discharge of the battery will also reduce its inner plate and reduce its life.
"Fully discharged graphene can not only increase the amount of electricity that the battery can maintain (
For example, run four fans for three hours instead of the first two hours)
But it also increases the number of full discharges it can withstand.
In addition to this, the advantage of this graphene formula is that adding it to the battery does not require any changes in the manufacturing process.
"For example, the manufacturer added four powders to the paste inside the battery, and now he has to add five powders," Mr. Singhal said.
More than 95% of energy storage devices in India use lead-acid batteries, including motor vehicles, inverters and solar energy storage devices, according to Singhar.
However, the company is also working on similar advances in lithium-ion battery technology --
Like those in the phone. in the future.
