Alsym Energy Battery Lab

The performance of lithium ion at a fraction of the cost and risk

Alsym™ Energy has developed an innovative low-cost, high-performance rechargeable energy storage technology that’s free of lithium and cobalt, and ideal for applications such as stationary storage, maritime shipping, two-wheelers and electric vehicles.

By using readily available, inherently non-toxic and non-flammable energy storage materials, Alsym is working to deliver wide-duration storage with performance comparable to lithium ion at a much lower cost, speeding the pace of decarbonization for people around the world.

Stationary & Grid Storage

Stationary & Grid Storage

Electricity generation is shifting to renewables, but solar and wind power must be backed up at scale to ensure 24/7 availability. High battery prices are slowing the pace of storage deployment, and storage integrators are competing with automakers for supply. Lithium-ion systems are mostly unsuitable for urbanized areas due to fire risks and production of highly toxic gases. As high-profile storage fires become more common, communities are working to delay or even block new storage installations.

Safer options exist, but most have low energy densities and low power with large footprints. With system-level capacities similar to lithium-ion and the ability to operate at ambient temperatures up to 45 C, Alsym is the only high-performance, non-flammable battery storage option capable of replacing lithium-ion in urban areas and hot climates. Alsym batteries are also less expensive to operate as they don’t require expensive climate control or liquid cooling systems.

Alsym technology combines fast charge rates and user-configurable discharge durations with high round-trip efficiency in a minimal footprint for maximum energy and power with low levelized cost of storage (LCOS). With high power density and on-demand user-configurable discharge rates, wide-duration Alsym batteries are an ideal solution for both short-duration and long-duration energy storage (LDES) needs.

There’s little tolerance for hazardous battery chemistries in maritime applications. The maritime sector has aggressive decarbonization targets, but extensive safety engineering makes lithium-ion systems expensive–up to 5 times higher on a per-kWh basis.

Unlike lithium-ion batteries, Alsym batteries are made from materials that are inherently non-flammable, reducing the risks to human life and cargo and helping to lower insurance costs and cumulative liabilities.

Alsym batteries can be used for both hybrid and fully-electric vessel applications, as well as off-shore wind farms, oil and gas platforms, and drilling rigs.

Motorcyles, Scooters, & Two-Wheelers

The global electric motorcycle and scooter market is set to triple by 2030. Today, over sixty million are sold every year, and most run on fossil fuels. Battery electric models are in demand, but buyers are extremely cost-sensitive and concerned about battery fires. Lithium-ion batteries in two wheelers can spontaneously combust due to poor heat dissipation—a problem that will only get worse as the world warms.

Our low-cost, non-flammable batteries are poised to be an ideal solution for the two-wheeler market, maximizing performance and profit margins while greatly improving rider safety.

Electric Vehicles

Even with recent advancements, the cost of lithium-ion batteries is still higher than what’s needed for EVs to reach cost parity with comparable internal combustion engine (ICE) vehicles. This means that most EVs are being purchased by affluent buyers in wealthy nations. Low-cost, high-performance Alsym batteries will enable global adoption of battery-electric vehicles across consumer and commercial segments.

Alsym batteries contain no lithium, cobalt, or nickel and use a non-flammable water-based electrolyte. They’re incapable of entering thermal runaway and catching fire, reducing the likelihood of battery recalls and cumulative liabilities.
