Discarded EV batteries are still functional as li-ion batteries are advantageous in low discharge rate, long life cycle, as well as high energy density in energy storage efficiency. Both EVs and large energy storage equipment are highly dependent on li-ion batteries. ...  more

In February, Chinese battery supplier CALB and the government of Shenzhen’s Futian District signed a strategic cooperation framework agreement. This event constitutes a formal declaration that CALB has landed its international HQ in Futian District. ...  more

Swiss Federal Railways servers as the lifeline of the country’s tourism and transportation, and now a Swiss startup has come up with an idea that paves solar panels between either sides of the railway tracks to make the best use of these tracks that are usually idling. ...  more

On March 1st, 2023, Tongwei's international sales team presented modules to the local market together with Minlea, a well-known Austrian photovoltaic supplier at Energie Sparmesse Expoenergy, and both parties signed a 100MW Tongwe...  more

There will be several millions of discarded EVs awaiting disposal after a few years, and the li-ion batteries contained within these EVs can actually be used for something else other than being recycled, reused, and remade into new batteries. A large solar and energy storage hybrid system that is recently established in California is formed with 1,300 batteries from discarded EVs. ...  more

The demand for batteries has been rising alongside trends of energy transformation and net-zero emission, where major materials contained within batteries, including lithium, nickel, cobalt, and graphite, are becoming increasingly scarce and exorbitant, which is why the recycling of batteries has become an emphasis for the future. ...  more

The manufacturing principle of the Tongwei Terra series shingled module is to connect the cells in series through adhesives, and then form a power generation array through multiple series and parallel connections. Such a high-dens...  more
