The New Results Of Dalian Institute Of Technology Have Increased The Cycle Life Of Nickel-zinc Batteries By 10 Times.

- Apr 24, 2018-

Recently, li mingqiang, an associate professor at dalian university of technology, made a breakthrough in green power batteries, which increased the cycle life of nickel-zinc batteries by 10 times.The results were published in nature.

As a kind of power battery, nickel-zinc battery has many advantages, especially the safety and environmental protection features are best suited to drive electric buses.However, the current commercial nickel and zinc batteries generally have short circulation life, and the cycle life is rarely more than 1000 times, which greatly limits its application in electric vehicles.

Li mingqiang and zhang xiaoliang, an associate professor at the university, used zinc oxide to create a new type of nickel and zinc battery anode material for use in secondary batteries.Capacity of battery cycle life of up to 10000 times, the attenuation rate is only 0.0011%, the maximum discharge capacity is 2603 mah/g, effectively solve the problem of low nickel zinc battery cathode cycle life, the literature has significant improvement.

The team assembled the results in an electric bicycle based on the battery and a 5kw liquid-flow energy storage battery module, and conducted trial production in the relevant enterprises.
