Alternatives to lithium-ion batteries have been hyped for a number of years as sodium is much cheaper than lithium so the expected price drop from sodium-ion battery is eagerly anticipated to reduce cost of EV cars. Alternatives to lithium-ion batteries such as sodium-ion have been talked about for years, but here is the first of the EV cars to be produced. Article on Lithium-ion battery lithium Battery Improvements here.

“The first generation of mass-produced sodium-ion batteries has been installed in a production electric car for the first time. The model is part of VW’s joint venture Sehold brand in China and can cover 157 miles on a charge with the Na-ion battery that is much cheaper and safer than its lithium counterparts

The world’s first mass production of sodium-ion batteries, developed by HiNa Battery, has reportedly begun with an initial 1 GWh capacity, scheduled to reach 3-5 GWh in 2024. HiNa says they focus on low-cost, long-life, high-safety and high-energy density Na-ion battery products. The potential applications cover low-speed electric vehicles.

  • The car is a low speed, city based car
  • Range 150 miles (250km)
  • HiNa’s Na-ion cells have 145 Wh/kg energy density
  • Good for 4,500 full charge-discharge cycles

The company’s research is now geared towards developing the second generation

  • 200 Wh/kg energy density
  • Double its charge cycles.

Energy density is one of the disadvantages of Na-ion batteries as sodium is quite a bit heavier than lithium, so they can’t really achieve Li-ion cell density.
