Graphene supercapacitors will even start an excavator: Pioneer2 motor starter unveiled

The problem of starting a car engine with problems with a regular battery occurs quite often. The American startup Team XHE decided to eliminate this problem even on powerful engines. The crown-firing platform shows the Pioneer2 car launcher, built on graphene ionistors.

The use of ionistors instead of high-current lithium batteries has several advantages in starting devices:

• Short charge time (claimed up to 10 minutes)
• Wider temperature range of application (-40…+70° С)
• Unlimited number of charge cycles
• High starting current
• And graphene models of ionistors (supercapacitors), unlike conventional ones (with coal), have a higher energy storage density.

The Pioneer2 model uses 3000 F supercapacitors (equivalent to 22.5 Ah of lithium battery capacity). The total voltage of the assembly of ionisters is 16.2 V. This power-to-weight ratio allows the device to start engines up to 10 liters with a starting peak current of up to 2000 A.

Operation with the Pioneer2 launcher is no different from other devices of this type.

The dimensions of the plastic case of this useful gadget are 270x220x146 mm, weight 4 kg.

Estimated cost of Pioneer2 will be from $134 USD. Production is planned for the end of the year.
