Batteries are used on spacecraft as a means of power storage. Primary batteries contain all their usable energy when assembled and can only be discharged. Secondary batteries can be recharged from some other energy source, such as solar panels or radioisotope-based power (), and can deliver power during periods when the space vehicle is out of direct sunlight.
Arumugam Manthiram and John B. Goodenough first identified the polyanion class of cathode materials for lithium ion batteries. [9] [10] [11] LiFePO4 was then identified as a cathode material belonging to the polyanion class for use in batteries in 1996 by Padhi et al. [12] [13] Reversible extraction of lithium from LiFePO
The best NMC batteries exhibit specific energy values of over 300 Wh/kg. Notably, the specific energy of Panasonic’s “2170” NCA batteries used in Tesla’s 2020 Model 3 mid-size sedan is around 260 Wh/kg, which is 70% of its "pure chemicals" value. LFP batteries also exhibit a lower operating voltage than other lithium-ion battery types.
Internally stored energy generally takes the form of unused propellant [1] and batteries. [2] In the past, such stored energy has sometimes led to fragmentation or explosion, producing unwanted space debris. [1] [2] This was a fairly common outcome for many of the U.S. [3] and Soviet rocket designs from the 1960s to the 1980s. [4]
The explosion, observed on March 7, was the second brightest gamma-ray burst ever witnessed by telescopes in more than 50 years of observations, over one million times brighter than the entire ...

The battery packs are produced by GS Yuasa, the same company that supplies the batteries for the Boeing 787 Dreamliner, whose entire fleet was grounded in January 2013 for battery problems. The lithium-ion battery of an i-MiEV caught fire at the Mizushima battery pack assembly plant on March 18 while connected to a charge-discharge test equipment.
