The new non-flammable battery provides 10 times more energy and runs for 110 hours.

Battery innovations are driving the development of electronic devices, robotics, electric vehicles and modern cars. However, making batteries safer in a variety of environments and in widespread use has proven to be a challenge for developers.

Some battery fire incidents have also dampened customer interest in electric vehicles and larger battery-powered machines.

In this regard, the startup has developed a non-flammable battery. High-performance, non-flammable and non-toxic Alsym Energy batteries are designed to replace lithium cells.

Alsym batteries, billed as a low-cost solution, support a wide range of discharge durations.

New battery chemistry

The company claims that its new battery the chemistry is not related to anything currently available on the market.

Their metal oxide battery chemistry uses a mechanism similar to that used in lithium-ion batteries, in which working ions move between the anode and cathode.

Although functionally similar to lithium-ion cells, Alsym batteries use non-flammable, non-toxic materials and a water-based electrolyte.

Without dendrites

This design makes Alsym elements inherently dendrite-free, preventing runaway overheating and its potentially catastrophic consequences.

Alsym co-founder and MIT professor Kripa Varanasi said renewable energy sources are intermittent, so “you need storage, and to really solve the decarbonization problem, we need to be able to make these energy sources intermittent.” batteries anywhere at a low price.”

The company believes its batteries, which are currently being tested by potential customers around the world, have huge potential to decarbonize the high-emission industrial manufacturing sector, and they see other applications ranging from mining to powering data centers. homes and utility companies, it is reported. MIT News.

Flexible storage duration

Alsym claims to use environmentally friendly, non-toxic materials, reducing environmental impact and supply chain risks.

It also offers more flexible storage durations, from 2 to 110 hours, allowing it to be tailored to different energy storage needs. And it’s high performance in terms of Round Trip Efficiency (RTE), power charging power and speed. Finally, its levelized cost of storage is comparable to or lower than lithium-ion storage systems for fixed solutions. according to to the company.

Alsym claims its batteries are a safe and non-toxic alternative to lithium cells. Unlike lithium-ion batteries, which can pose a fire hazard, Alsym batteries are designed to avoid these risks, offering a safer solution for residential and commercial applications.

“Compared to other non-lithium batteries, Alsym Green has 2-10 times higher energy density, making it a more compact and powerful solution for 20ft DC container units,” said company in a statement.

“Additionally, it has best-in-class round-trip efficiency (RTE) of 92%, fast charging (C/4), low self-discharge (<0.25% per day) and adjustable discharge duration from 2 to 110 hours. Overall, it has performance characteristics that no other non-lithium battery can match.”

1.7 megawatt-hours of electricity

While the batteries don’t quite reach the energy density of lithium-ion batteries, Varanasi says Alsym ranks high among alternative chemistries at the system level. The 20-foot containers with Alsym batteries can provide 1.7 megawatt-hours of electricity, he said. MIT News.

Alsym co-founder and CEO Mukesh Chatter said the company is helping to decarbonize markets in ways that were not possible before. Chatter stressed that no chemical or steel plant would dare place a lithium battery near its premises due to its flammability.

“We’re highly customizable and that’s important because depending on where you are, you can sometimes run two cycles a day with solar, and when combined with wind you can actually have electricity 24 hours a day, 7 days per week.” said Chatter. “The need for multi-day or long-term storage is a small part of the market, but we support that too.”
