American manufacturer promises solid battery in 2019

There is no one who is seriously involved in the battery business for the automotive sector who is not developing solid battery technology while continuing to optimize existing lithium-ion batteries. But there are also companies like the Charge CCCV, an American startup founded specifically to develop solid batteries and put them on the market as soon as possible.Charge CCCV was born at Binghamton University in New York and for years has been working out the C4V's patented solution to produce solid batteries, optimizing chemical structures and producing specific electrodes for a variety of purposes. Starting with batteries for electric cars.According to Charge CCCV technicians, who have recently presented their new cells at a conference in New York, they are currently achieving energy densities of 380 Wh / kg, expected to reach 400 Wh / kg before going into series production, an impressive figure when compared to the Tesla Model 3 cells, which are considered to be the most efficient on the market, but stand at 207 Wh / kg. This allows you to design a battery for a vehicle like the Renault Zoe or the Nissan Leaf (40 kWh) with only 100 kg, or 250 kg, if you think of the Tesla 100 kWh batteries.Lighter and less bulky, the C4Vs are not 100% solid, since only 80% of the liquid electrolyte has been replaced by a solid material, making the Charge CCCV batteries, so to speak, semi-solid. Still, they will be able to accept higher loads without heating as much as current lithium-ion batteries, and because they do not require cobalt - one of the most expensive and most expensive materials in modern batteries - will always be cheaper.
Assuring a further 70% of autonomy, the C4V will allow a vehicle that today announces about 300 km between refills, raise this bar to 510 km. The prototypes of the new batteries have long been in the testing phase, with serial production scheduled for the first half of 2019, sometime during the second quarter. It will be the first solid battery to be manufactured, with C4V drawing attention to the fact that QuantumScape, which is developing a similar solution and has recently benefited from a Volkswagen Group investment of close to 900 million euros, only plans to manufacture in series to its solid battery in 2025.
