  • Patent number: 8927125
    Abstract: A quencher for a flow cell battery is described. The quencher utilizes a quench solution formed from FeCl2 in a dilute HCl solution in order to quench chlorine emissions from the flow cell battery. A quench sensor is further described. The quench sensor monitors the concentration level of FeCl2 in the quench solution and may also monitor the level of the quench solution in the quencher.

  • Patent number: 8911696
    Abstract: High purity MnO and zinc oxide may be efficiently recovered from alkaline and/or carbon zinc batteries using a process involving the treatment of the crushed batteries with an alkali hydroxide to produce insoluble manganese oxides and an alkali zincate solution. Zinc oxide is obtained by reacting the zinc solution with carbon dioxide or an acid such as a mineral acid and furnacing. The manganese oxides are converted to MnO by furnacing under an inert atmosphere.

  • Patent number: 8734972
    Abstract: Provided is a battery pack processing apparatus and a processing method with which discharge can be performed in a short time when a battery pack is discharged by immersing the battery pack in a discharge liquid. A processing apparatus A is for discharging a battery pack P having single cells c and a case b by immersing the battery pack P in the discharge liquid. The processing apparatus A includes an aperture-forming machine 20 forming an aperture through which the discharge liquid can flow inside the case b by pressurizing the battery pack P. A state can thus be achieved which is the same as the state that results if the single cells c accommodated in the case b are individually immersed in the discharge liquid. A protection circuit f for preventing an over-discharge is prevented from suppressing a discharge current from the battery pack P, enabling the discharge in a short time.

  • Publication number: 20140106185
    Abstract: Technologies for recycling rechargeable batteries are described. For example, a rechargeable battery may be recycled through a cycle that includes one or more of determining a battery condition while the rechargeable battery may be used in a networkable device, updating a rechargeable battery database with the battery condition over a network, determining recycling instructions, and outputting the recycling instructions on the networkable device. In other examples, multiple rechargeable batteries may be recycled by receiving battery conditions and identification codes over a network, updating a rechargeable battery database with battery conditions and identification codes, and assigning rechargeable batteries to recycling processes according to battery conditions and identification codes.
