Scientists have developed an innovative battery that retains 80% capacity after 8,000 recharge cycles

A breakthrough in battery technology by scientists at Linköping University in Sweden could revolutionize access to electricity in poor regions. A newly developed battery composed of zinc and lignin offers a cost-effective and environmentally friendly solution for energy storage.

Lead researcher Reverence Crispin of the Organic Electronics Laboratory emphasizes the importance of this innovation for regions that rely heavily on solar energy.

Despite the prevalence of solar panels in tropical countries, the lack of energy storage after sunset slows progress. The new battery aims to solve this problem by storing excess energy during the day for later use.

The zinc-lignin battery can boast an impressive service life:

  • It is able to withstand over 8,000 recharge cycles, while retaining 80% of its capacity< /strong>.
  • In terms of energy density, it is not inferior to lead-acid batteries, but does not cause the environmental damage associated with lead.
  • In addition, it can maintain a charge up to week, surpassing the capabilities of other types of batteries.

To overcome the instability inherent in zinc batteries, scientists used a water-polymer electrolyte based on potassium polyacrylate. This innovation increases the stability of the battery during charge and discharge cycles.

In addition, the cost-effectiveness of this technology makes it a compelling alternative to lithium-ion batteries, which raise safety and environmental concerns.

Ziauddin Khan, a co-author of the study, mentions the disadvantages of lithium-ion batteries, in particular, their explosiveness and environmental impact. He argues that the new battery offers a viable alternative, especially where energy density is not a priority.

When will we see a working battery?

Although current prototypes are small, the potential to scale to sizes comparable to car batteries is promising. Funding from Swedish research funds and government initiatives have contributed to the development of this sustainable technology.
