2. A123 Systems - Wikipedia

   en.wikipedia.org/wiki/A123_Systems

   In May 2011, A123 introduced a lithium-ion 12 V engine starter battery designed as a lighter-weight, longer-lasting and more environmentally friendly drop-in replacement for lead acid batteries. [41] A123's Nanophosphate® Engine Start Battery was selected to R&D Magazine's 2011 R&D 100, which salutes the 100 most technologically significant ...

3. Magnesium battery - Wikipedia

   en.wikipedia.org/wiki/Magnesium_battery

   A magnesium–air battery has a theoretical operating voltage of 3.1 V and energy density of 6.8 kWh/kg. General Electric produced a magnesium–air battery operating in neutral NaCl solution as early as the 1960s. The magnesium–air battery is a primary cell, but has the potential to be 'refuelable' by replacement of the anode and electrolyte.

   LiFePO4 3.2 V. LiFePO4 properties: long-lasting (2000+ cycles), safer, more stable, good continuous/peak discharge rates (3C/10C), less energy dense. These cylindrical cells are widely used in EVs, including electric bikes, electric scooters, electric cars / hybrid electric cars, UPS batteries, storage batteries for solar power systems, starter ...

5. Nickel–metal hydride battery - Wikipedia

   en.wikipedia.org/wiki/Nickel–metal_hydride_battery

   Most manufacturers claim that overcharging is safe at very low currents, below 0.1 C (C/10) (where C is the current equivalent to the capacity of the battery divided by one hour). [23] The Panasonic NiMH charging manual warns that overcharging for long enough can damage a battery and suggests limiting the total charging time to 10–20 hours. [22]

6. Lithium iron phosphate battery - Wikipedia

   en.wikipedia.org/wiki/Lithium_iron_phosphate_battery

   The energy density (energy/volume) of a new LFP battery as of 2008 was some 14% lower than that of a new LiCoO 2 battery. [45] Since discharge rate is a percentage of battery capacity, a higher rate can be achieved by using a larger battery (more ampere hours) if low-current batteries must be used.
