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.
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.
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
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.
