Graphene Manufacturing Group (GMG) has announced that its graphene aluminium-ion batteries (“G+AI Battery”) 2032 type coin cell prototypes have been sent to a number of prospective customers around the world.
GMG reports that coin cell testing to date has demonstrated that the GMG 2032 type G+AI Battery coin cell prototypes are fully rechargeable in several seconds, retain capacity for several thousand charge and discharge cycles, are non-flammable, and are relatively non-toxic and almost fully recyclable. These characteristics compare favorably against typical rechargeable Lithium-Ion 2032 type coin cells which take 3-6 hours to recharge, are toxic and can be quite harmful if ingested, are difficult to recycle, are flammable under certain conditions, and degrade more rapidly in performance.
