What We Do

Starting with your requirements,MaxPower’s team will develop and optimize every aspect of your battery design. MaxPower’s batteries can be designed to perform in the most demanding conditions, such as extreme temperature variations, high g forces and vibrational loads, high power needs, and much more.

Primary Batteries

A primary battery is a non-rechargeable battery designed for a single use. These batteries usually offer higher specific capacities than their rechargeable counterparts since their non-rechargeable nature allows the use of solid metal anodes. 

MaxPower offers primary batteries in a wide array of configurations including uncommon cathode materials such as Vanadium Pentoxide (V2O5) and others. Though MaxPower is focused on primary batteries using a lithium metal anode, many other materials like sodium, potassium, magnesium and others are possible.   MaxPower offers both standard and custom batteries geometries, including 18650, 21700, CR123, A-D cells, and many more.

Secondary​ Batteries

Differing from primary batteries, a secondary battery is a rechargeable battery designed for repeated use. Though specific capacities can be somewhat lower than in primary batteries of comparable chemistry, their rechargeable nature often makes these cells much more useful. An enormous number of different secondary battery configurations exist, all having their own unique applications.     

MaxPower has experience with many of these battery types, and the team is always ready for a new challenge. As with primary batteries, MaxPower offers both standard and custom battery geometries, including 18650, 21700, CR123, A-D cells, and many more.

Reserve Batteries

Less common than primary or secondary batteries, reserve batteries are primary batteries designed for an extremely long shelf life of 20+ years or more. Often, the battery electrolyte is pressurized and stored in a vessel inside the battery case. When power is needed, a mechanism punctures this vessel and releases the electrolyte, thus activating the battery. 

These batteries are often used for defensive applications where long standby times are needed, such as ballistic missiles or SAM systems. These batteries can also be used on spacecraft where long mission times require a dormant battery.   

As with other battery types, MaxPower offers extensive R&D capabilities reserve battery performance characteristics as well as electrolyte storage/ distribution systems and storage lifetime testing.    

Notable Research Activities

In addition to our extensive lineup of primary, secondary, and reserve batteries, MaxPower has also been involved with many research-intensive projects. These projects are often in partnership with academic institutions, the US government, or larger production companies.    


Throughout the years, MaxPower has worked with solid state batteries, lithium seawater batteries, lithium air batteries, lithium metal secondary batteries, and many more. Recently, MaxPower has been involved in the R&D of experimental Lithium Sulfur batteries.
