Lithium Sulfur Dioxide Battery Manufacturers Attract Funding

From:CTECHI GROUP Limited     Release time:2018-09-18

Overview:Two lithium sulfur dioxide battery manufacturers devoted to develop lithium sulfur battery, which could be higher energy-dense but less expensive than today's lithium-ion batteries, have received large boosts to their funding.

Two lithium sulfur dioxide battery manufacturers devoted to develop lithium sulfur battery, which could be higher energy-dense but less expensive than today's lithium-ion batteries, have received large boosts to their funding.

Baseload Renewables has raised over 7 million dollars from an undisclosed investor. Baseload is going to spend the money in improving its lithium sulfur battery project, which are designed to meet rapidly increasing demand of high energy density batteries.

Baseload's batteries feature cheap, readily available sulfur dissolved in water as the positive electrode. The company anticipates that its technology will reduce at least 60% of the cost of equivalent lithium-ion batteries. The company raised almost $2 million from MIT's technology incubator, the Engine, when it just launched last year.

Meanwhile, U.K.-based Oxis Energy, a researcher of batteries featuring a lithium anode and a sulfur-based negative electrode, says it has raised over 5 million dollars from Aerotec, a Brazilian private-owned equity fund. The Aerotec investment will enable Oxis to set up a subsidiary and R&D center in Brazil.

But not all lithium sulfur battery technology development has gone as planned. Sion Power, a battery materials start-up in which BASF invested $50 million in 2012, tells C&EN it has shelved its liso2 primary lithium batteries research.

"It was a technology decision," says Sion's marketing director, Andy Black. The company is now pursuing lithium-ion battery technology featuring a lithium anode rather than the usual carbon positive electrode. With 450 charging cycles, the lithium positive electrode technology can handle an order of magnitude more cycles than the company's lithium-sulfur anode technology. "The decision we made was all about the numbers," Kliever says.
