High Performance
The highest performing non-lithium battery
Alsym offers the highest-performing non-lithium battery for BESS. Its performance profile offers energy density that is 2x to 10x higher than competing technologies, provides fast charge (4 hours) and flexible discharge (2 to 110 hours), and 92% round-trip efficiency. Its non-toxic, non-flammable design, combined with low self-discharge (<0.25% per day) and industry-leading LCOS, makes it the ideal choice for stationary energy storage.
Non-Flammable & Non-Toxic
No fires, no explosions, no toxic gases
Alsym’s inherently non-flammable, non-toxic, non-lithium battery chemistry can’t catch fire. With a water-based electrolyte and containing no lithium, cobalt, or organic solvents, Alsym batteries provides a level of safety that is desperately needed but can’t be met by lithium-ion. This makes it the only option viable option for stationary storage applications where safety is critical and space is limited.
Flexible Wide-Duration Storage
A single solution for discharge durations from 2 to 110 hours
With any solution, the more problems it solves the more value it has. The same is true for batteries. With discharge rates from 2 to 110 hours and the ability to recharge to full capacity in under 4 hours, wide-duration Alsym batteries can be used for short and long-duration needs, helping boost your return on investment. Cycle twice per day to take advantage of short-duration revenue opportunities, or select a longer discharge duration to support intra-day load shifting and multi-day outages. This flexibility is what makes Alsym an ideal battery technology for a wide range of use cases.
Low Cost
The affordable alternative to lithium-ion
With low material costs, low manufacturing costs, and low system-level levelized cost of storage (LCOS), Alsym batteries are a single, economical solution for use in short and long-duration energy storage applications.
